Weapons: Adcor Defense BEAR Elite– A Free Floating Barreled, One Piece Anti-tilt Bolt Carrier Piston AR

Filed under: Weapons — Tags: , , , , , — Matt @ 1:06 PM

This is a very interesting rifle. To be able to shoot sub-MOA after 6,000 rounds worth of testing at HP White is impressive for a piston AR. Not to mention the excellent durability and lack of malfunctions during the HP White testing. This rifle will be competing in the Army’s Improved Carbine competition, and it looks like a contender.

The thing about this rifle that grabbed my attention is the free floating barrel. To not have anything touching that barrel, is a radical departure from the norm. That equates to some excellent accuracy capability, and I would really like to see this rifle chambered in 7.62 or other interesting calibers. With nothing touching the barrel, then folks could experiment with different barrels and really explore the field of AR accuracy. But for a standard battle rifle, this is awesome. (it would be cool to see different offerings of barrels, with different twists like 1/8)

The one piece anti-tilt bolt carrier assembly is smart as well. With a recessed lug going into the carrier, that will only increase the strength and durability of the connection between the piston rod and bolt carrier. There is a lot of force in this particular area of the rifle, and anything to make that system more robust is good. Attaching the piston rod to the carrier just makes sense and you won’t see carrier tilt like you would with other systems that do not attach the piston rod to the bolt carrier.

The other really cool thing with this rifle is the regulator. Having the ability to regulate the piston operation is crucial to keeping it running good, or to operating the weapon with a suppressor. Although honestly I was not able to determine the full scope of this regulator, and it would be cool to hear Adcor expand further on this part of the weapon.

The non-reciprocating charging handle can be placed on either side of the weapon, which is cool too. It is just a more natural position for a charging handle than where it currently is located. You can still charge the weapon with the original charging handle though. It gives the shooter options, and I like that.

The dust wiper shield is another feature I am interested in, but really cannot make a judgement. If it is made out of polymer, then it will wear down I would think? Or polymer pieces might break off and fall into the operating system. So to me, I just don’t know about that part of the weapon.

Overall, I think it is pretty cool that Adcor went from designing and building intricate parts for missiles and aircraft, to designing a better piston gun. It is almost like a black swan event where a designer from a totally different discipline comes in, and changes the field of weapons design by making a different and highly accurate version of a piston gun. The free floating barrel and one piece piston rod/bolt carrier set up will please many shooters out there that have been looking for a good piston AR. So we will see what the Army thinks and what the shooting community thinks about the Adcor Defense BEAR Elite. –Matt

B.E.A.R.™ Elite: A world class automatic rifle from Adcor Defense
• Magpul MOE™ rifle stock
• Magpul MOE™ ergonomic rifle grip with aggressive texturing
• FN Manufacturing 1:7 twist, hammer-forged, chrome-lined barrel with M249 rifling profile for long life and exceptional accuracy
• Available with sights or optics ready
• Forward placed, reversible/ambidextrous charging handle
• Gas piston system with multi-position regulator
• Free-floating barrel
• Chambered for 5.56
• Ejection port dust wiper

A New Perspective on the Automatic Rifle: The B.E.A.R.™ combines design innovation and precision manufacturing built upon the tried and true M4/M16 rifle platform.
The Adcor Defense B.E.A.R.™ springs from the M4/M16 rifle platform but offers a completely new twist. Available in many configurations, it offers the operator many significant improvements:

A Revolutionary Gas Piston System (Patent # 065111.00128)
• Free-floating barrel and increased accuracy: A gas-driven piston incorporated into the upper half of the forward rail system never touches the barrel.
• No carrier tilt: The operating rod is connected to the bolt carrier by hex head bolts reinforced with industrial grade Loctite® 262™ high strength threadlocker. They are then drilled and pinned to prevent loosening under adverse conditions.  The operating rod then rides through a machined boss in the receiver rail system interface keeping the bolt carrier in a linear plane as it operates.
• No fouling of chamber and action: Hot gases and carbon particulates are prevented from entering the receiver. Because heat reaching the upper receiver is diminished, lubricant lasts longer and maintenance is simplified.
• Easily detached lower rail system: No special tools needed for quick cleaning and easy maintenance.
• Wear on critical parts is minimized: The operator can easily adjust the piston’s cyclical rate for a controlled rate of fire.
• No need for piston rings: Extremely close machine tolerances of the piston eliminate the need.

Exclusive Port Dust Wiper with Cover
• Prevents entry of dust, sand or debris: The spring-loaded dust shield mounted on the bolt carrier allows the bolt carrier’s return to ready position; the port dust wiper moves into the ejection port opening flush with the inside geometry of the upper receiver.
• Withstands temperature extremes because of the highly durable, self-lubricating polymer shield.

Ambidextrous Forward Placed Charging Handle: Simplicity is Beautiful.
• Simple design allows the operator to keep his or her strong hand on the firearm and use the other hand to clear the rifle.
• Ambidextrous handle detaches easily without special tools and returns to locked position once used. It folds forward, recessed, and easily swings back out in a single motion.
• Non-reciprocating handle only engages when the operator charges or clears.

Rail System ( 7075-T6 )
• Innovative, key locked, highly rigid rail system mounts seamlessly to the upper receiver: Design ensures proper alignment of the rail with a redesigned boss, spline and groove system.
• Upper and lower rail guards separate with the push of a button: No special tools necessary.
• Fully compatible with optical, image intensification or thermal sights; laser targeting systems; bipods; tactical lights and Multiple Integrated Laser Engagement System (MILES).

Company Spotlight: Primary Weapons Systems

    You know, a lot is said about the various weapons companies and defense companies in the East coast or in the Southwest, but you never hear a lot about the fantastic companies in other parts of the country. And specifically, you never hear much about my neck of the woods here in Idaho. Companies like Primary Weapons Systems, Chris Reeve KnivesMilt Sparks holstersGemtech suppressors, Cheytac precision rifle systems, and the list goes on. In the future I plan on doing more company spotlights on Idaho companies that offer some quality equipment, weapons, and weapon parts.

    So with that said, let me get started. I have a friend named Dave who works at PWS and he invited me on down to the shop to check out the operation and the guns. While there, I got to see where all the magic happens and talk to some of the folks that make that happen. Stacey Nagy was one of those folks, and he was very helpful and informative as well. A big thanks to both for showing me around.

    PWS is probably most famous for their compensators. They reduce felt recoil of the rifle, keep the muzzle steady and reduce the flash. You will see these compensators on many competition and field weapons being used out there, and the fit and finish of these things are fantastic. They are also designed to fit the popular suppressors being used.  And believe me, when you see all the attention to detail that the company goes through to produce these compensators and get them out the door to their customers, then you will definitely appreciate what you have when you get one.

     They are also in the market of making parts that will help to support this ‘AR piston’ craze that is sweeping the weapons manufacturing world. Everyone is making an AR piston gun or retrofit kit it seems, and they are all experiencing issues with modifying the AR to operate a piston. That is were PWS comes in.

     Another part I got a chance to check out was their new buffer tubes, and I was very impressed. It is one of those parts on an AR that I have seen fail or I have seen installed incorrectly on a weapon, and this new PWS buffer tube will help to fix many of those issues. You do not have to peen a castle nut and possibly ruin the finish of your weapon, and installing it only requires an allen wrench and following the directions. (check out the comments about the buffer tube on the site) The ridged/fluted aspect of the buffer tube also provides strength to the thing and they look cool.

    Probably what is most important though is that these buffer tubes are designed to deal with piston guns that have had issues in the buffer tube area. Notice how they have a specific buffer tube kit for the HK 416? (hint- there are problems with this gun) These buffer tubes have built in quick detach points and supposedly they reduce recoil as well. Bravo to PWS for making the better buffer tube and I hope they sell a lot of them.

    Finally, and this is the one that should be of interest to the companies out there, and that is PWS makes piston AR rifles. My first interest in PWS rifles was their cool little Diablo gun that fired 7.62 x 39 ammo. That thing was cool and here is a video of it in action. But once I started researching what PWS is all about and what they have produced, I wanted to learn first hand about what else they had to offer.

    Specifically, these guys are making AR piston guns that not only have the ergonomics of the AR, but have the internal operations of an AK style piston system. And that is what is unique here. They modeled the design of their piston systems on this world famous weapon and they have created a true ‘long stroke piston’ AR. So what you are getting with a PWS weapon, is an AR/AK hybrid. The best of both worlds, thrown into one weapon.

    The other big selling point of their weapons was weight. They are close to one pound lighter than their competitors who market similar piston guns. So not only are they tough, reliable and simple, but they are also lightweight.

    On a side note, they are also running the excellent BCM Gunfighter charging handles that you see many folks running on their ARs. These charging handles are tough and make charging the weapon a lot easier than with the standard charging handle in ARs. This is a fine addition to the PWS weapon.

    The barrels are also standard AR type hardened barrels with 1:8 twist and chrome lining, which will be nice for durability and for using different bullets weights. At the shop, they purposely feed as many types of ammo as possible through the guns to see how they operate. Especially the cheap low grade ammo, which you see PSC/PMC’s resort to using all the time for overseas work. I have yet to be on a contract where the company issued Blackhills ammo or something similar. It is always the cheapest or middle of the road ammo, or it is ammo that they got from the military. Having a piston rifle that can be fed with all types of factory ammo is definitely a plus.

    I even asked them about problems with the rifles, and it sounds like the barrels wear out before the piston systems wear out. But the big one here that I clued in on is that no one is sending their rifles back because ‘they are falling apart’. These things are built to last, and have the best features of the AK and the AR incorporated into the design. Did I mention that they have a 7.62 x 51 AR piston gun they just introduced? They will even make a 6.8 piston gun if you ask.

   Not only that, but Paul Howe of CSAT is now recommending this rifle on his website. He has mentioned them twice in his newsletters and the rifle is in his ‘recommended equipment’ section here. As everyone knows, Paul has had some bad experiences with another piston gun that I won’t mention, so for him to endorse this AR piston gun says a lot. (Although I am sure after he runs it over time, he will be able to provide more input about the weapon.)

    Finally, there is the part of this visit that I really was impressed with, and that was the customer service aspect of this company. Everyone there was very helpful, friendly and honest about answering my questions. They really helped me to get a good picture of the AR piston industry and what their company has to offer. It is a confusing and fast paced part of the industry, and everyone is trying to make the best product out there. It is exciting to watch and PWS is working hard to become a leader in this field. –Matt
