Built to be lightweight and fast-handling, the Wilson Combat Protector Carbine AR-15 Semi-Auto Rifle represents the AR at its most advanced. The heart and soul of the rifle is the match-grade, precision button-rifled, stainless steel barrel that's tested for accuracy and finished with Wilson's Q-Comp muzzle device that provides excellent recoil control. Inside the mil-spec forged upper and lower receiver set, the Protector Carbine features Wilson's exclusive 2-stage Tactical Trigger Unit for a trouble-free, crisp 4-lb. trigger pull every time along with modular construction that simplifies takedown and cleaning. The free-floating M-LOK handguard has a slim, ergonomic profile and shields the nitride-finished gas block. Wilson's Armor-Tuff coating is applied over the mil-spec hard-anodized finish for even more corrosion resistance. Finished off with advanced furniture like the Wilson Combat/BCM pistol grip and a Rogers Super-Stoc, the Protector is a high-performance AR that's ready for duty.
