The Primary Weapon Systems MK216 Mod 1-M Complete AR-10 Upper Receiver is built to be more than just a standard semi-automatic AR platform. It features a 16” barrel chambered in .308 Win designed for long range precision shooting. What sets this upper apart from the rest is the 3 position adjustable long stroke gas piston system built for reliability with any ammunition type, suppressed or unsuppressed. The free float handguard has a cutout to easily reach the gas system for quick adjustments. Additionally, the handguard has M-LOK attachment slots and a continuous picatinny top rail that is flush with the receiver. The forged upper receiver features a slick side design without forward assist to reduce weight. This .308 Win complete upper receiver comes with a proprietary bolt carrier group and Radian Raptor ambidextrous charging handle.
