Barrel: PSA 16" 4150V Chrome Moly Vanadium steel barrel, chambered in 5.56 NATO with a 1:7 twist rate, M4 barrel extension, and a mid-length gas system.  Gen2 PA-15 barrels come standard with a dimpled barrel to allow easier indexing and installation, as well as a more secure fit, of aftermarket gas blocks. The Nitrided Gas Tube is a Mil-Spec Stainless gas tube so it is designed to withstand high heat and resist corrosion, and the Nitride finish helps the tube maintain a presentable finish for a longer period of time.  The Barrel is finished off with a PSA 13.5" Lightweight M-Lok Free Float Rail which features anti-slip set screws that help ensure the rail is securely attached to the barrel nut.  The rail also features multiple QD attachment points for slings.  Other features include the .750 low-profile gas block and an A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. These uppers are made for us right here in the USA by a mil-spec manufacturer.

Bolt Carrier Group: ToolCraft BCG has a bolt made of mil-spec shot-peened Carpenter 158 steel. Gas key is secured with grade 8 fasteners and staked per mil-spec.
