Barrel and Gas System

The Bear Creek Arsenal barrel runs 10.5 inches long, chambered in 5.56 NATO and built from 4150 chrome moly vanadium steel with a Parkerized finish and M4 profile. It carries a 1:8 twist rate. Gas cycles back to the action through a carbine-length system, running a carbine-length stainless steel gas tube.

Front Sight Base and Muzzle Device

A fixed A2-style front sight base sits at the front of the barrel, doubling as a sling attachment point. Capping the muzzle is an A2 birdcage flash hider.

Upper Receiver and Handguard

The upper receiver is a 7000 Series optimized AR-15 flat-top unit, machined from aluminum and finished in Type III black hardcoat anodizing, featuring a dust cover pin feature with the ejection port door included. Over the barrel sits a two-piece drop-in carbine handguard finished in FDE, using an M-LOK attachment system along its length.

Bolt Carrier Group and Charging Handle

A complete AR-15 bolt carrier group is included, made in the USA and listed for use across 5.56 NATO, .223 Remington, .300 Blackout, and .350 Legend. That broader listing describes the BCG itself; the barrel and chambering on this upper remain 5.56 NATO. A standard AR-15 M4 charging handle rounds out the upper's operating components.
