Bear Creek Arsenal BC-10 Features The Bear Creek Arsenal BC-10 is built on an AR-10 platform with a forged lower receiver and a 16 heavy-profile barrel machined from 4150 Chrome Moly Vanadium steel with a Parkerized finish that provides excellent corrosion resistance and durability under sustained hard use. The mid-length gas system balances dwell time and bolt velocity for reliable cycling across a wide range of .308 Winchester loads and the 1:10 twist rate stabilizes the full spectrum of .308 projectile weights from lightweight varmint loads to heavy-for-caliber hunting and precision bullets. The E9310 steel bolt and AR-10 feed ramp geometry provide the strength and reliability that the .308 Winchester cartridge demands from a semi-automatic platform across extended range sessions and field use. The rear-charging configuration keeps the charging handle out of the top rail space allowing optics to be mounted further forward for a more natural cheekweld without the charging handle clearance concerns that standard forward-charging AR-10 designs introduce. The M-LOK split rail handguard provides a lightweight versatile accessory mounting platform for lights lasers bipods and grips across the full length of the handguard and the 5/8x24 threaded muzzle supports the widest range of compatible muzzle devices and .308-rated suppressors without additional machining. For hunters and precision shooters who want a complete factory-built AR-10 in .308 Winchester with a heavy-profile CMV barrel mid-length gas and M-LOK handguard for sale at GrabAGun the Bear Creek Arsenal BC-10 delivers a capable platform at an exceptional value.
