The barrel is 10.5 inches long and is made from 4150 Chrome Moly Vanadium which is super strong, accurate, heat resistant, and corrosion-resistant as well. The barrel has a 1/2″-28 thread pitch and comes with a standard A2 style flash hider.

The low-profile gas block fits nicely inside the handguard, and it uses a carbine-length gas tube, which is ideal for a 10.5-inch barrel.
