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

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).

A guy posted on M4C about his, he had some issues if I recall. It is a very interesting design with some neat features.

To be honest, I'm more interested in PWS (in 7.62x39 only though, if it was 5.56 I'd just go with a DI rifle).

P.S. ADCOR posting a vid about a supposedly cutting edge AR design and using a monopod grip (or whatever the f**k they call it) does not inspire confidence.:D

hmmmmm
 
I Can't say it is the "Ultimate AR" because a KAC lower is better than there lower. The folding charging handle looks interesting, but with thick gloves during winter how easy is that to grab under stress, over all the charging handle is not that appealing to me. Not to mention is that easy to dislodge when going through thick brush and what happens when coming out of the water?

I could keep going on, but really I just have a lot of questions on that design....

Also the charging handle might get in the way when setting up my lights and laser as well....just not sure about this one....
 
I tought it was interesting, until I saw the bipod grip

"one of our engineers, started playing with a computer"
call of duty I bet
 
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.

Since when is a free floated barrel so radical? Guy makes it sound like the second coming.
 
One of the reasons the AR platform is amazing is because everybody has a different idea of what the "ideal/ best" version is, according to their personal likes and purposes.

I understand that that is their idea of the ultimate AR, but I really don't think there is such a thing anymore, it is only what is best to the user.

Its not so much that free floating is such a new feature, its that the gas piston system that usually "slaps" the barrel when it's firing is not integrated into the hand guard, with a little gas tube that goes between the barrel and piston system, much like the gas tube on a regular AR15. When the gun fires and the barrel vibrates it allows that repeatable movement you can zero on. The piston is only putting its forces on the upper and the handguard, and it looks to me like they use regular AR15 uppers instead of an expensive monolithic rail upper like the Vltor or LMT MRP.

Obviously the barrel isn't completely 100% free floated because there is some contact between the barrel and piston system with the gas tube link, but from what it looks like there is a certain forgiveness or allowable movement so the barrel can freely vibrate when it's fired.


All in all, I think it's a neat concept. But time will definitely tell if it turns out to be a good rifle or not.
 
The ultimate AR15 is the HK416. That being said, I have fondled the Adcor Defense AR and it's a pretty slick setup. There are a lot of neat features such as the removable gas piston, carrier dust cover and reversible forward charging handle (which I've gotten used to on my ACR). If I was looking for a new piston AR this would definitely be at the top of my list.
 
The only drawback I can see to this system is the weight of the carrier on the operating rod.if the rod very strong,hard wearing material and they say it is high carbon steel,then the weak link will be the material which the operating rod is bearing upon,which is either the forward portion of the upper receiver and/or the upper section of the handguard.there is a fulcrum effect as a result of this design which may be its achilles heel.need more info.
 
I wouldn't call it the altimate AR-15 because it's not an AR-15. Real AR-15s don't have pistons or free float barrels or any of the other mods that this rifle has..

so its an AR made by everyone else and assembled by them

Well, that doesn't mean anything really.

What does BCM make? Nothing. They assemble components, high quality, built to the mil-spec. Their rifles are high quality and 100% reliable.


I couldn't care less for ANY piston AR-15.
 
Just thought that I would post some info about this rifle like who is selling it:
http://www.canadiangunnutz.com/forum/showthread.php?t=705381
And how this system works:

Also apon recieving this upper I can tell you that the bolt is MP and still retains its gas band. Actually it works in my other AR just fine. No I have not shot it without the charging handel but will try it this weekend. The BCG is chromed and full auto with a shrouded firing pin that is also chromed. The Op-Rod is properly staked to the BCG and there is a modification that was done to the BCG to accomidate the plastic wiper. Also the dust cover door is not compatible with any other AR15's due to it's lock up mechinism. The barrel is REALLY nice and well worth the $$$ in my opinon. Although the only thing I did not like was that it did not come with there front post sight that was made for this rifle. Will post a review of the groupings later on along with a report of any issues I might have like not being able to mount anything on the left hand side due to the placement of the charging handel.
