Barrel and Gas System

This upper uses an 8.5 inch barrel made from 4150 Chrome Moly Vanadium with a Parkerized finish and a heavy profile. The 1:9 twist rate is suited to a wide range of .300 Blackout bullet weights, and the 5/8x24 thread pitch matches the included flash can muzzle device. A pistol length gas system runs to a gas block sized at 0.750. The barrel and gas components make up the front end of this complete upper.

Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum and finished with a durable anodized coating. A freefloat MLOK handguard made from aircraft-grade aluminum in black surrounds the barrel without contacting it, giving this upper a compact exterior forend built for a short pistol length platform.

Bolt Carrier Group and Muzzle Device

The included bolt carrier group is made from 9310 alloy steel with a Nitride finish. A flash can muzzle device threaded at 5/8x24 completes the muzzle end hardware for this upper.
