This complete rifle is probably one of the best firearms for the entry-level shooter and comes with everything necessary for reliable duty carry. The barrel is machined 4150-grade moly vanadium steel and, for additional protection and durability, has a QPQ Nitride coating on the inside and the outside.Remaining faithful to their function over form motto, Sons of Liberty Gun Works protects the barrel and their EX02 free-float handguard and multiple M-LOK slots for maximized customizing.The handguard also sports a pinch-lock barrel nut attachment, making it the most durable on the market today. With an upper receiver forged from 7075-TG aluminum, type III class 2 hard coat black anodized finish, the Exo2 AR can take a beating in the field and continue functioning as expected. Also included in the Sons of Liberty Gun Works EXO2 receiver is a forward assist and dust cover and a SOLGW BCG and BCM Mod4 charging handle. Sons of Liberty Gun Works also includes a dry film lube inside the receiver to ensure decreased friction and far smoother bolt carrier action.As much attention as Sons of Liberty Gun Works placed on the upper receiver, they deck out the lower receiver with a few aftermarket benefits you will be proud to have. Rounding out this semi-automatic is a B5 systems carbine stock and a pistol grip for better grip ergonomics.If you want a classic semi-automatic 5.56 NATO round carbine and expect it to function as needed regardless of the dynamic situation or inclement weather, the NATO Law Enforcement Rifle made by Sons Of Liberty Gun Works is the rifle for you.
