Among the best rifles in the AR-15 world is one many shooters have never heard of—the Adcor Defense B.E.A.R. (Brown Enhanced Automatic Rifle) may be the best buy.
If you have fired a modern rifle with a big name with a monolithic receiver and rail, it just may have sported a receiver made by Adcor. The Adcor AR-15 features a monolithic receiver and quad rail that offers a great deal of utility and a modern appearance.
B.E.A.R. Features and Specs
The Brown Enhanced Automatic Rifle, named for its inventor, is offered in both the standard gas impingement system and a gas piston type. My example is the gas impingement rifle. The original rifle featured a floating gas system that many find attractive.
My rifle also features the floating barrel and rigid rail system. The Adcor B.E.A.R. features first-class assembly, fit and finish. Every piece is made in the USA. A special bolt design protects the ejection port from debris, dust, and other material entering the rifle.
While I conducted initial firing with the supplied MagPul fixed sights, later during the test program my rifle was fitted with a TruGlo Omnia rifle scope. Here are the specifications for the Omnia:
- Multi-coated lenses for enhanced clarity and contrast
- 30mm tube for increased turret adjustment range and increased brightness
- Locking target turrets that prevent accidental adjustment
- 1/2-MOA target turrets and MOA based reticle for simplified adjustments, tracking and holdover
- APTUS-M1 mount for a stronghold and ideal mounting position on modern sporting rifles
- Illuminated All Purpose Tactical Reticle (A.P.T.R.) for precision measurement without a crowded sight picture
- Hardcoat anodized matte finish
- Nitrogen gas-filled, fog-proof construction
- Water-resistant and shock-resistant design
- Illuminated glass-etched reticle
- Leaf-spring turret control for positive and responsive click adjustments
- Generous eye relief
Testing the B.E.A.R.
To begin the test, I fired the rifle with the supplied MagPul fixed sights. I loaded a mix of MagPul and C Products magazines with Winchester USA’s 55-grain FMJ. The bolt was lubricated with Ballistol and I began the test firing.
The rifle handles well, with a good balance. The quad rail provides excellent balance and a good gripping surface. The trigger breaks at 6.0 pounds even. While the trigger isn’t light, it is even and consistent. The rifle is fast on target.
There were no problems with reliability with any of the ammunition tested. I ran a single magazine of steel cased Tula loads with good results as far as function. The rifle turned in good results at longer ranges within the limitations of iron sights.
I elected to mount the TruGlo Omnia and test it with several loads that have given good results in other rifles. Among these was the Winchester Ready 62-grain FMJ. At a long 100 yards, this loading demonstrated a one-inch, three-shot group on average.
Moving to the new Winchester 77-grain Match loading, I was able to fire a 0.8-inch three-shot group, with an average of three groups at 0.92 inches. The Adcor is clearly accurate enough for any chore. The rifle is reliable, fast handling, and offers a good reserve of ammunition.
With the TruGlo scoped added, the rifle has good utility as a hunting rifle, especially for coyote and other varmints. Whatever the AR-15 will do, the Adcor will do and it will accomplish the chores better than most.
I went a bit further on the testing as I elected to adopt the Adcor and the Omnia as my emergency rifles. The design is simple. I especially like the All-Purpose Tactical Reticle. The ladder of hash marks is calibrated for 55-grain loads, but far from useless with 62-grain loads.
A big advantage of the initial low magnification is that you may fire with both eyes open. It is quite easy to move the handle quickly to bring the elevation up for longer shots. The scope offered excellent accuracy at longer range.
If you use alternate 5.56 mm /.223 loads, such as the popular 60, 62, 75 and 77-grain loads, the scope and hash marks are useful once you have memorized the point of aim and point of impact. The Adcor/TruGlo combination is a good one.
I have enjoyed firing this rifle and evaluating it with different ammunition and sights. The rifle is a solid choice as a go-anywhere, do-anything rifle.
