The Primary Weapon Systems MK111 Mod 2-M Complete AR-15 Upper Receiver is built to be more than just a standard AR15 complete upper. It features a 11.85” barrel chambered in .223 Wylde. However, what sets it apart 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 features picatinny rail segments at the front. The forged upper receiver features a slick side design without forward assist to reduce weight. This AR-15 complete upper receiver comes with a proprietary bolt carrier group and Radian Raptor ambidextrous charging handle.
