What do you do if you are a fan of the 7.62x39mm round but not of the AK-variant rifles usually made in that caliber? You get a Bear Creek Arsenal (BCA) AR-15 Complete 7.62×39 rifle! And since it’s a Bear Creek, the gun features a side-charging handle.
The Bear Creek Arsenal AR-15 Complete 7.62×39 Rifle
The rifle is a hybrid of sorts: an AR-15 platform rifle chambered in the popular “AK-round.” It’s also an AR built without the charging handle operated from the rear of the receiver, which I consider the weak link in the AR rifle. Instead, this rifle sports a curved charging handle on the right side of the receiver. It’s easy to manipulate and quick to charge.
I recently ran 250 rounds through a BCA AR-15 chambered in the popular 7.62×39, and I was impressed with the rifle’s functionality, its smooth operation, solid controls and accuracy. Anyone thinking about a rifle in this round needs to take a close look at this BCA offering.
Features
My AR-15 Complete 7.62×39 rifle featured a heavy-profile 16-inch barrel made of 416R stainless steel, with a parkerized finish and a 1:10 twist rate. It operated via a carbine-length gas system.
The rifle also sported a 15-inch M-LOK rail, an M4 flat-top billeted upper receiver, and BCA’s Bolt Carrier Group, Flash Hider, and a right-side charging handle. The BCA mil-spec AR-15 lower was forged aluminum. The stock is adjustable for length. The rifle sells with two 30-round, curved magazines.
The trigger on my rifle broke at 3 pounds, 6 ounces on average. The trigger was a mil-spec model, and as mil-specs go, pretty good. Still, there was some gritty feeling to the trigger and enough stacking that could possibly make for an uneven trigger pull.
Great Glass
I mounted a Mark 5HD 2-10×30 FFP rifle scope, manufactured by Leupold, atop the BCA’s receiver. As I reviewed and used the scope many times, I knew it was great glass for any rifle, but it worked especially well with AR-platform rifles.
The Mark 5HD featured Leupold’s Tactical Milling Reticle or TMR. The TMR is Leupold’s redesign of the MIL reticle and employs hash marks instead of dots for increased ranging and holdover precision. The reticle also provided aiming points for both wind and bullet drop compensation.
The Mark 5HD 2-10’s elevation turret provided 30 MILs of adjustment in 0.1 MIL increments. Leupold’s patented ZeroLock set screw ensured the elevation dial would not move when knocked around. The scope measured just 11.2 inches in length and weighed in at 24 ounces.
A scope needs mounting hardware, and I used a rock-solid Leupold Mark IMS 35mm Bolt-Action mount.
AR-15 Complete 7.62×39 Rifle Accuracy
At my outdoor range, I first zeroed the rifle using Winchester Ammunition Target & Practice 7.62×39 ammunition, loaded with 123-grain full metal jacket bullets. The precise controls of the Mark 5HD 2-10 quickly got me on target.
My last three shots at this distance came in at .63 inches.
At my 100-yard lane, the BCA shot high. A few scope adjustments got me right on target.
I was still running the Winchester ammo, and my best five-shot groups came in at .75- and 1.1-inches.
I then tried out Hornady 7.62×39, launching a 123-grain SST poly-tipped round. The top groups were at 1.13- and 1.4-inches.
Last, I ran the BCA with Federal Ammunition Fusion hunting rounds and their 123-grain soft-pointed bullet designed with a molecularly-fused jacket. I placed a three-shot group right at 1.0-inches, and five shots at .90-inches.
Mag Problems
I also pegged five-shot groups in the 1.5- to 2.0-inch range with all three brands of ammunition. But I do think the BCA AR-15 7.62×39 is an MOA rifle.
As the shooter, I do take some of the blame for those larger-than-MOA groups. I know I definitely pulled more than a couple shots. The trigger could benefit from an after-market upgrade, too.
I also had problems finding a consistent, solid position shooting from a bench with that ridiculous 30-round AK-style magazine sticking down a full six inches below the end of the mag well. A web search revealed no 10 or 20 round magazine options for the rifle and round.
Friends on the manufacturing side of the industry tell me the taper on the brass of the 7.62×39 cartridge made the magazine’s curve necessary. I was also informed that one of the magazine manufacturers has figured out a way to build a straight mag for the round but has hesitated to build it due to profitability concerns.
If it helps, I will buy the first dozen straight mags!
I want to hunt with the BCA 7.62×39, but that silly banana mag has to go. (If anyone knows of a non-curved option, please let me know!)

Solid Choice
Mags aside, the BCA AR-15 Complete 7.62×39 is a very solid rifle, and it operated much smoother and all-around better than any AK-style rifle I’ve tried. AKs have a long history of military functionality and continue to show up at conflicts around the globe.
All true. Yet, the AKs I have used all felt clunky, rattled a good deal, and were never close to 1 MOA rifles. That’s my experience, at least.
Power-wise, the 7.62×39 round is more than adequate for close to mid-range hunting, and the round’s military history certainly says it is competent for home defense.
BCA has done a fine job making an AR-15 in the AK round, and if I can ever find the right style magazines, I will be taking this rifle afield for many years to come.
