Accuracy:Can expect 3/4 MOA


Developed by Eugene Stoner, This rifle exhibits some of the characteristics of his former designs, notably the AR-10 and the M-16. However, this is not just an upgraded assualt rifle, but was designed from the beginning as a sniper rifle. There has been mixed results about this rifle. Some people swear by them, and others do not like them at all. (The 1st SFG comes to mind here). The accuracy has never been an issue, they all tend to be VERY accurate, with .5 MOA attainable. But the reliability during field operations has been questionable. If you decide to go with one of these rifles, you will need to maintain a very tight maintenance schedule to insure reliability, and prolonged field operations will require very close attention. The SR-25 is manufactured by Knights Mfg Co.

Remington 700 Milspec 5R


Remington 700 Milspec 5R

Remington 700 Milspec 5R
Caliber:.308 Win (7.62x51 NATO)
Barrel:Stainless Milspec 5R
Barrel Length:24" (610mm)
Twist:RH 1:11.2"
Weight (Rifle only):8.25 lbs (3.75 kg)

Price:Around $1050 USD

The Remington 700 Milspec 5R rifle was first introduced as a limited edition rifle back around the turn of the 21st century, and ever since then it has been of keen interest to many shooters. The ability to have a rifle with the same barrel as the M24 SWS used by the US Army, and other nations around the world, but at a fraction of the $6000 price tag of the M24 is a big drawing point. While the milspec is not a standard item in the Remington catalog, it is still being made when possible and they are still popular. We decide to take a look at one more closely and give it a good testing here.

As our readers know, we have reviewed quite a few Remington 700 based tactical rifles and after a while they do kind of all seem fairly similar so it takes some effort to point out the things that set one apart from another. The milspec rifles have an interesting history about them that does make them unique. Whether unique is good or bad will depend on each person�s perspective in this case. The single big thing that makes the milspec unique, and consequently gives it the milspec name, is the barrel. The way the milspec came about, as told to me by a Remington LE division employee, was a byproduct of the M24 production line. There are specific tolerances that each M24 Barrel must achieve in order to pass inspection. As is normal in any production line some of the barrels will not meet those specifications and Remington would toss those barrels into the "no-go" pile and discard them (I am not sure where they used to go from there). It turns out that someone had the idea of taking those barrels that did not pass inspection and re-contour the barrel to the standard Remington heavy barrel contour, mount it to a Remington 700 stainless action, and call it a "Milspec" rifle. Since there are not a large number of barrels that do not pass inspection the rifle were considered a limited edition rifle.




Now, this was how it all started, and to be honest I do not know if that is where the barrels continue to come from today or if they are new production on the M24 tooling. Either way, the barrels are a unique 1:11.2" twist, as found on the M24, and have the 5R rifling which is also unique to the M24 and I believe the 40X target rifles as well. I will not get into the claimed merits of the 5R rifling, but I will mention that it does have a strong following of top notch barrel and rifle makers and I have no reason to dispute the merits of the rifling when backed by so many of the top rifle and barrel makers out there.

The barrel is 24" in length which is also different than the normal Remington 26" barrels. I personally prefer this length and the rifle feels very nicely balanced. The M24 barrels are stainless and as such so are these barrels. The barrels have the standard Remington 11 degree tapered target crown and as I mentioned earlier, the contour is the same as the normal Remington heavy barrel contour found on their 700P's, varmint rifles, and others. The M24 has a much heavier contour, similar to a #8 or so, so that is a noticeable difference.




The action is a standard Remington 700 action though in this case it is stainless steel to match the barrel. Like most Remington 700 actions, this one was very smooth and nice to operate. The bolt handle, floorplate, extractor, box magazine, etc are all standard Remington 700. The M24 has a steel floorplate and a black powder coating over the metal work, but these milspec rifles only share the core barrel and have the standard, and less durable, alloy floorplate and no finish on the stainless metal.

These latest batches of milspec rifles have the now standard XMark Pro trigger. We are not a huge fan of this trigger but this one did come from the factory set at a decent breaking 3.5 lbs according to our trigger scale. My biggest complaint with the introduction of the XMark Pro traiiger was the moving away from the ribbed trigger shoe and the removal of the more refined trigger adjustments, now it is down to a more simple single screw for weight of pull and that is it. In reality this is probably not such a big deal to a vast majority of shooter, but somethings we just grow to prefer. We did not adjust the trigger during our tests here and the factory setting worked fairly well.




The stock is a HS Precision stock that is actually a little different than the 700P and Varmint Synthetic (VS) stocks. The most noticeable difference is that the milspec stock has a green speckling over the black and while visually it is hard to even notice, it does provide some added gripping friction while in use, and yet it is another unique thing to help the milspec be a little different than the normal Remington.

Additionally the actual forearm area has a slightly different contour to it than the 700P stock, with a more pronounced beaver tail style. The forearm area is also about 1.75" shorter than the 700P stock, I am assuming this is because the barrel is 2" shorter and aesthetically the shorter stock probably looks better and it also saves a little bit of weight. The stock has the same 700P palm swell which I like but others do not, and it has the same thin rubber recoil pad. The pistol grip is also the same short pistol grip and I typically have to curl my pinky under it when shooting. All in all, I have always liked the 700P stock and this one is just slightly different and I find it just as nice.




The overall balance, look, and feel of the rifle are very nice. It is not large and bulky like many of the new tactical rifles and it is fairly light, our scales showing it at 8.25 lbs with no scope mounted. Of course, some coloring on the barrel will be required for tactical use and that can be done temporarily with the ol' krylon spray paint can if needed, or you could have a more professional finish applied.

For testing purposes we mounted a Leupold VX3 6.5-20x50mm Target scope using Leupold Mk4 Rings and Base. The rifle handles like a normal 700P but a few inches shorter. The fairly light weight, for a tactical rifle, and minimal recoil pad leads to a bit more brisk felt recoil than most of the heavier tactical rifles, but the 308 cartridge is a tame cartridge and the recoil is still very manageable. The rifle fires well from the sandbag as well as the bipod and is not as bad as many to shoot from unconventional shooting positions.

Because of the unique rate of twist I wanted to try a wide variety for bullet weights from 155 to 190gr to see if one stood out as being well suited to the 11.2" twist rate. The designers of the M24 performed tests and calculations to determine that 11.2" was the ideal rate of twist for the sniping ammo at the time, the 173gr M118 Special Ball. Based on that, I figured the 175gr match might perform the best in the milspec. While that was not necessarily true, what we did find out is that it fired all of them just about the same! In fact, I have included a picture below of a target that was fired consecutively with Federal Gold Medal Match 168gr (Upper Left), HSM 190gr Match (Upper Right), and HSM 155gr Match (Lower Right). They almost look like they could have been from the same lot. I will say that the barrel and rifle appear to be quite flexible in terms of what it can fire well.




I thought that the rifle would not stabilize the 190gr bullets at all, but at least in the short range it works fine. I did not test the 190's at longer ranges where it still might loose stability as the bullet slows down. If you want to take advantage of the heavier 190gr bullets I would advise some more testing at long ranges, but at 100 yards, it shot very well from this rifle. The best group from the rifle was fired with Federal GMM 168gr and measured .460" center to center, but the better overall average was achieved with HSM 190gr and 155gr, but there were only a couple of groups each fired with those loads. The HSM 175gr was right about the same as the GMM on average.

100 Yard Accuracy
LoadBestAverage
HSM 155gr HPBT Match.490".604"
Federal GMM 168gr HPBT.460".712"
HSM 175gr HPBT Match.702".722"
HSM 190gr HPBT Match.542".548"


The rifle performed well shooting right in that .5-.75 MOA range that most of the new heavy barrel production Remingtons are shooting. The 175gr loads were extremely consistent, more so than any of the others though the ultimate accuracy was not as good as with the other loads. But like all rifle, finding the right load will probably result in even better performance.

So what are the conclusions? Well, the performance is not anything better than what we have found in other Remington offerings, but there are some unique features on the rifle that do set it apart, primarily the barrel and rate of twist. Is it worth the $200 premium over a standard 700P? That will depend on the requirements of your team. The stainless barrel is nice, but unless your need heavier bullets than 175gr, I would say the 11.2" twist rate is not a big enough reason to go with it as a 1:12" is not that much slower and will stabilize the 175's. . The 5R rifling is unique and may well be worth some extra expense and may be one of the reasons for the consistency across different ammo makes and weights. The stock is a little different as well, though not drastically, and there is no real functional improvement over the normal 700P stock. Do I personally like it better than the 700P? Yes, I do, because of the shorter 24" barrel, 5R rifling, and the stainless is good to have for operations in all environmental conditions. Does it perform any better? No... not really, at least not in our test with a brand new, unbroken in rifle. I do feel it is a nice alternative to have available in the Remington lineup.... rejected M24 barrel or not.

Well, here we are, another new year, and another few new tactical models introduced by Remington. Of all the rifle makers out there, Remington seems to be the one taking the most advantage of the tactical rifle popularity by introducing a couple of new tactical rifles just about every year. One of the new ones this year is the Remington 700 VTR, or Varmint-Tactical Rifle. This particular rifle has a few new twists to make it unique and we ordered one in to test these new twists and see just what kind of a tactical rifle the VTR is.



Yes, here is another Remington 700 with the same action as on all the other Remington 700's we have reviewed. There is not a whole bunch to talk about in regards to the 700 action that we have not covered in all the other Remington 700 tactical rifles and custom built rifle reviews we have done. But, there are some things that are different that makes this review worth doing. To me, I'm not really sure who the target customer is for this rifle, beyond the tacti-cool crowd. It is a lightweight and compact rifle design, but the last time I checked, Remington was quite successful with the 700LTR rifles as well as their extremely popular, and good performing,SPS Tactical rifle introduced last year. This rifle is about the same weight as those two and fits in-between in price. But the one thing this rifle does have that is different, is the very unique barrel profile and integrated muzzlebrake.



As you can see in the photo above and below, the profile of the barrel is not a round profile like a typical rifle barrel, but is triangulated. Essentially, what it appears to be is that Remington took the LTR fluting and continued the flute all the way out, making the barrel a triangle. Looking at this objectively, beyond saving weight, I do not see what this particular profile does? Unlike a traditional fluted barrel, you actually reduce the amount of surface area which hurts with heat dissipation and barrel cool down, and as far as I can tell, you are making the barrel less rigid which should lead to degraded accuracy, but I'll reserve that final judgment until after the shooting sessions. The triangle also gives a nice flat surface area where Remington engraved a nice looking VTR logo.



The other feature the VTR has that the LTR and SPS-T do not, is the integrated muzzlebrake. A well designed brake can reduce a lot of felt recoil as well keep the muzzle flip down helping with rapid follow up shots. This muzzlebrake has three large slots cut into the top of the triangle, angled slightly back to help "pull" the rifle forward, reducing the felt recoil and keeping the muzzle down. The brake is about 2" long and is not a part of the barrel, so in reality, the 22" barrel is really 20" effective inches, making it the same as the LTR and SPS-T.



The stock on the VTR is the same stock that is found on the SPS Varmint rifle, but green instead of black, and they did make the inserts on the stock a rubberized material, which actually is a nice upgrade, but the stock is still injection molded and made of a fairly weak plastic and the barrel is not free floated as a result. It is fairly comfortable to shoot and the forearm is fairly wide and provides a stable enough shooting platform. It does have a Monte Carlo style cheekpiece, but it is not raised so it does not aide in bringing your eye in line with the scope like a normal raised Monte Carlo design does. Overall, like on the SPS Varmint, the stock is functional but nothing to write home about.

The VTR has the X-Mark Pro trigger which just about all Remington 700s have now. The trigger is fine, but I still prefer the old Remington trigger with its wider ribbed shoe and more options for adjustability. This one broke fairly clean right at 5 lbs. It is heavier than I like, but not bad for a factory trigger. The X-Mark Pro triggers do have a single adjustment that you can lighten the pull with, but we did not adjust the trigger at all for this evaluation.

The rest of the rifle is pretty much standard Remington 700. The action is as smooth as all Remington 700s, it has the same two position safety, the bolt release is in the same place, and it has the same extractor etc. So all the positives about a Remington 700 and all the negatives about a Remington 700 are there.



For the Shooting portion of the evaluation we mounted a Swift 6-18x50mm with mildots with a set of Burris XTR bases and Leupold Rings. We fired both standard Federal Gold Medal match and the nice HSM 168gr Match ammo. For zeroing the scope and doing some initial groups, the weather was terrible, which can happen in the spring in Montana. It was about 25 degrees with blowing snow. When we went back out for the performance evaluation, the weather was fairly nice at about 45 degrees in the early morning with calm wind, which made nice shooting conditions.

The first thing we noticed is that the muzzlebrake really was not that effective at reducing felt recoil. The rifle is fairly light, but not overly so, and the recoil on the rifle felt about the same as a LTR or SPS-Tactical. But the muzzle flip was less which did allow for quicker target acquisition after firing. I thought that the recoil reduction should be more than it was, as it did not seem to perform as well as most of the modern muzzlebrakes on the commercial market. Now, I will admit that we have no equipment for measuring the exact figure in terms of reduced recoil; this is just a personal comparison between rifles we have shot before.

The VTR shoots ok, but I would not say good, at least in comparison to the other heavy barrel Remington rifles available. We did manage to get one sub .5" group at 100 yards, but we had to really work at it. The small group of the day was .448", but the average group size of the good groups fired (meaning no obviously bad called flyers, etc) was only .858". This is not quite up to the normal accuracy we typically will see out of a 700P, LTR, SPS-Varmint, etc. I believe this is due to the drastic reduction of metal that is removed making the triangle barrel profile. Though the accuracy is still sub 1 MOA, it is just not what we have come to expect from Remington tactical/varmint rifles.

So, to conclude, how do we rate this rifle? Personally, I'm not sure what the target market is for the rifle, but I would not take it over any of the other Remington tactical type options out there. If I were looking for a short tactical rifle, I would much prefer to buy a LTR or even a SPS-Tactical where I would get a nicer stock and save some money while I'm at it, not to mention get better accuracy. The Muzzlebrake does not do quite enough to make it a real decision maker over the SPS-Tactical. Unfortunately, I just don't see the advantage of this rifle, but perhaps it'll fill a niche somewhere.

We recently performed a review on the Remington 700 SPS-Varmint to test the suitability of that rifle as a tactical rifle, but this time around we will be testing the Remington 700 SPS Tactical rifle to see how well it performs. The SPS Tactical is only available through Remington premium dealers, but in reality they should be fairly easy to find. These rifles are specifically labeled and marketed as a tactical rifle and as such we will be evaluating it as a tactical rifle and not a varmint rifle filling a tactical rifle role. We ordered a rifle from our supplier and prepared for the evaluation.
The 700 SPS Tactical is setup to be a compact tactical rifle that is easy to transport and usable in any weather condition. To achieve this at a reasonable price, a SPS trademark, Remington used a shortened varmint barrel (20") and an off the shelf Hogue Over-molded stock. These stocks have been around for a while and are fairly popular with shooters. The design is fairly typical for a rifle stock with a flatter type forend that remains fairly wide to provide a stable shooting platform off of sandbags or other shooting rests. I would prefer a pistol grip that had a bit more girth to it and was a bit more vertical, but it works okay as is.
The thing that sets the Hogue stock apart is the soft rubber compound that the exterior is made of. It provides and excellent gripping surface in all weather conditions and is warm to the touch. Another interesting point about it is that it is very quite if you bang it against something. While the audible quietness is perhaps not a major factor to consider, it is still a benefit. The rubber is molded over a ribbed plastic frame like many injection molded stocks, and like those stocks, this stock is not as stiff as I would like a stock to be. In fact, while using a bipod, the forend flexes enough to touch the barrel slightly. While it did not seem to affect the accuracy of this particular rifle, it is still a precision rifle no-no that should be avoided. This stock has the two aluminum pillars which work well enough for an economy rifle like this, obviously glass or aluminum bedding would be preferred, but that would raise the price considerably. The forend also only has a single stud without a specific 2nd stud dedicated for a bipod, making another minor inconvience.
The Barrel is free floating (until you use a bipod or a sandbag way up front on the forend) and is 20" in length. It is the standard Remington heavy barrel contour and does have a nice 11 degree target crown. The barrel channel gap on this example was nice and even the whole length, again, unless using it off a bipod causing it to touch at the very end. The action is a typical Remington 700 SPS action with the fairly rough matte finish over the entire barreled action. Unfortunately the SPS Tactical comes with the new Remington X Mark Pro trigger which I am not a big fan of, though I will admit it had a fairly clean 4 pound break. I just do not like the trigger shoe itself, the color, or the adjustment of it... perhaps I'm just a traditionalist. The trigger was kept at its factory setting for all testing here.

Even taking the flaws into consideration, the overall package is not bad for the money. The 20" barrel is just about right and the rifle balances well and is fairly light and easy to carry in the field. For the money it appears to be a solid package though obviously not perfect, but we still needed to check the performance before making any final conclusions.

The Remington 700P LTR with its fluted 20" barrel has a reputation of being the most accurate of the mass produced tactical rifles that Remington makes and many people believe that the 18-20" barrel lengths are ideal for the best accuracy with a .308, though you do give up some velocity. With the trigger left breaking at 4 lbs we expected some decent performance, though the stock sometimes touching the barrel did concern us. We used a Swift 6-18x scope for this evaluation and the groups were fired at 100 yards on about 16x. We used some cheaper 150gr 308 range ammo for the initial sight in, and things were not looking good with groups about 3". But then we changed to federal gold medal match 168gr ammo, things got better... MUCH better.

Here is a picture of three consecutive groups fired with the gold medal match ammo.
Now, they were not ALL that good primarily because of shooter error, but when you do three in a row like that, it is a pretty good indication of accuracy. All groups were fired at 100 yards using a sandbag upfront and sandsock at the rear. The three groups above measured .381", .362" and .313" respectively. The overall average for all groups fired with Federal GMM was .466". So, this particular rifle, even with the front of the rubber stock touching the barrel slightly, is clearly sub .5 MOA rifle out of the box. That is quite impressive for a $550 lower end tactical rifle. We did not try any of the other match grade ammunition, but it certainly likes the Federal. The trigger on this one didn't perform too bad at the range, though the recoil, as should be expected with the lighter weight and shorter barrel, was more brisk with more pronounced muzzleflip than a typical 700P or other longer and heavier .308 tactical rifles.

As is not totally uncommon with Remington rifles, the mounting holes were a bit off center and it took a decent amount of left scope adjustments to zero. There was still enough for wind situations, but it is still a sign of a bit of sloppy manufacturing.

In conclusion, it may be wise to mention the direct attack on FN-PBR sales that this rifle will have. The FN PBR is about $300-$400 more expensive, uses the same stock but with the full aluminum bedding block, the action isn't as smooth, and the one I tested was not as accurate. But, the FN-PBR does have a detachable magazine, claw extractor, wider gap in the barrel channel for no stock touching, that full aluminum bedding block, and it is available in some other barrel lengths. But to be honest, FN is probably not very happy about this little rifle, especially if Remington decides to keep it in the lineup after this year. Don't get me wrong, the SPS-Tactical has some legit weaknesses, but at the price, and if they all perform like this one, it will be hard to chose a PBR, or possibly even some other lower end rifles. Of course, you do give up some velocity with the shorter barrel, and some of the workmanship isn't the best, and some minor things like only a single stud up front keep it from being a truly great rifle, but the rifle does shoot very well and is completely functional in its intended role and deserves some consideration.
