Bear Creek Arsenal 6mm ARC Complete AR-15 Upper Receivers

Back in 2020, Hornady introduced its new 6mm ARC (Advanced Rifle Cartridge), designed for…someone…within the DoD. It provides high accuracy at long range while presenting a low felt recoil and is rapidly growing in popularity. And now Bear Creek Arsenal makes it easier for everyone to take advantage of the 6mm ARC in their AR-15 platform with its new complete upper receivers.

Available in seven options, the uppers are compatible with any Mil-Spec AR-15 lower receiver for fast, easy conversion. Likewise, they arrive turn-key and ready to shoot out of the box with an included BCG (bolt carrier group) and charging handle. As a result, all you need to get up and running are 6mm ARC magazines.

Designed to provide superior accuracy and performance, the uppers feature heavy barrels in 16-, 18-, 20-, or 24-inch lengths. However, the 16-inch barrel utilizes the M4 Contour profile as opposed to the heavy barrel.

Of the seven stainless steel barrel options, all but the 16-inch barrel feature straight flutes. As a result, they not only weigh less and provide more rigidity but promote faster cooling during courses of fire. Correspondingly, the free-floating handguard provides increased stability and barrel heat reduction. Additionally, top Picatinny rails and side M-LOK slots allow for attaching optics and other accessories.

The barrels all feature a 1:8 twist rate, providing better accuracy at long ranges, taking full advantage of the 6mm ARC round. In addition, the muzzle of each barrel includes a 5/8×24 thread pitch for running a suppressor or other muzzle device. Charging is handled via your choice of side-charging or rear-charging models.
