Robar’s PolymAR-15P Pistol Is the Real Deal

I’ve recently had the privilege of doing some solid T&E with the pistol iteration of the Robar PolymAR-15, and I have to say that I’ve been pretty impressed by it. Freddie Blish and Robar designed it from the ground up to lighten the load that law enforcement officers have to carry (literally), and regardless of which version you shoot, the first thing you notice is how well they followed through on that goal of weight reduction. More impressive, though, is the overall balance of the weapon because of how well they thought out the remainder of the specs.

PolymAR.4The PolymAR-15 is built around a KSP polymer upper/lower set with 7000-series aluminum reinforced pinholes. All of the small parts as well as the bolt carrier group are finished in Robar’s famous NP3, which provides both excellent corrosion resistance and a slick, teflon-infused nickel matrix that allows you to run the weapon dry without any issues whatsoever. For the ability to do that in the rifle you already own, Robar also plates customer-supplied BCGs if you send one in. (Previous review here)

The carbine-length gas system has a pretty smooth-feeling recoil impulse (considering the length of the barrel), and the 10.5″ 1:8 twist rate of the barrel stabilizes a wide range of bullet weights. The Bravo Company KMR9 forend is extremely light (only 3.8 ounces without hardware) because of its aluminum-magnesium alloy construction, which contributes to the overall balance of the pistol in a way that heavier rails just can’t do. The Sig SB15 arm brace is more functional than a standard pistol buffer tube, but the shorter length of it compared to a carbine stock on a rifle makes it easier for the gun to feel front heavy with a clunkier rail. In that regard, the KMR9 was the perfect choice.

 PolymAR.3The remainder of the specs are equally impressive, and this is an example of something being greater than just the sum of its parts (which are all pretty darn good in their own right). The interplay of the NP3 BCG and the polymer upper results in far less friction than with a standard BCG, and thus less heat transference. The BCMGUNFIGHTER ambi charging handle is one of the best on the market (the best, in my opinion). The upper/lower set is compatible with all mil-spec small parts, which means you can still install that aftermarket Wilson Combat or Geissele trigger without a hitch if you prefer. The trigger pull on this test gun measured in at just about 6.5 lbs and the NP3 smoothed it out a lot compared to other stock GI triggers. Still, if you plan to shoot it much you will probably find an aftermarket trigger preferable, particularly in the carbine or rifle because of the drastic difference a two-stage trigger can make in accuracy.

PolymAR.2Accuracy was good with Federal Gold Medal Match 69 grain .223 ammunition, but not all that much better than less expensive FMJ because we were just shooting it with the MBUS iron sights. Additionally, the 1:8 twist barrel should provide similar accuracy with a variety of different bullet weights, which was certainly my experience with everything from 55 to 77 grain ammunition. At 25 yards, groups with every round touching were the norm if the shooter did his part. Since it’s a pistol, I didn’t see the need to put an optic on it because the ranges I typically shoot pistols at are inside 50 yards anyway. The “P” model’s longer-barreled cousins come with guaranteed sub-MOA accuracy, though, so I am confident that with an optic or a 1–4 power the pistol would be capable of some impressive longer-range shooting as well.

PolymAR.1Robar has about 20,000 rounds through this particular gun so far (and 50,000 through one of the rifles) without any parts breakages or problems with the receivers, which is highly impressive from a durability standpoint considering some of the issues that have been known to happen with other brands of polymer (or even magnesium) lowers. Plus, they stand behind their product and you can be sure that they’ll take care of you if you ever have any issues with it. I have fired this gun with everything from GI mags and PMAGs to a Surefire 60 and several Lancer L5 AWMs and the gun ate up everything I fed it after I resolved a couple of easy-to-fix issues with the bolt. [Long version of the story: this was a SHOT Show gun that came to me right after it left the show floor in Vegas, which led to some early issues when I first took it out to the range. Both myself and the guys over at Robar failed to notice that the firing pin was still chopped from the show, which is mandated for guns that need to have firing pins in them on the floor in order to render them inert. Having said that, once I threw a spare firing pin and an o-ring into the gun it functioned flawlessly. This is largely moot because it is a step in the process that no regular customer would ever have to deal with, but I mention it here for the sake of full disclosure, as with all of my reviews.]

Overall, I give the PolymAR-15P high marks. It is accurate, light, and something different than what a lot of companies are putting out right now. From out-of-doors to out on patrol, this series of ARs is worth looking into if you’re someone who has to carry a lot of heavy gear around. Personally, I think I would derive more benefit from the carbine version, but that’s not a dig on the “P” model at all—I just shoot AR carbines more often than AR pistols. And for all of the .300 BLK fans out there, Robar also offers at least one of the models in .300, which would make for a quiet*, effective, and EXTREMELY light (sub-6 lb) shorter-range hunting carbine that could be plenty effective with the right bullet.

The PolymAR series carbine and rifle options are spec’d out equally well, and the retail pricing on these guns ranges from $1595–$1695. I was excited when I got to put my hands on one of these at the SHOT Show, and after shooting a lot of rounds through this one I can tell you that my first impression was on target. HP
