The Armalite AR-10 PRC308 Precision Rifle uses technology developed in partnership with Surgeon Rifles and AWC Silencers to offer a consistency in suppressed and unsuppressed configurations. A proprietary selectable gas block makes optimization for suppressed or unsuppressed applications easy for the user. The PRC308 features a Giessele Two-Stage trigger to provide crisp trigger pulls and reset, a Magpul PRS with adjustable length-of-pull and comb height and an ambidextrous safety and charging handle. It’s chambered in .308/7.62x51mm.
