Primary Weapons Systems MK114 MK1 Pinned Barrel 5.56 NATO FDE/Tan Rifle

Description

Product Overview

The Primary Weapons Systems MK114 MK1 is a 5.56 NATO semi-automatic rifle built around PWS’s long-stroke piston operating system. Its 14.5-inch barrel is pinned and welded to achieve a legal 16-inch configuration, while the collapsible synthetic stock provides adaptable handling and a compact storage profile. The FDE/Tan finish and railed handguard complement the rifle’s practical carbine design, offering mounting space for sights, lights, lasers, and other accessories. With a 32.9-inch overall length and a weight of 6 pounds, 15 ounces, the MK114 balances portability with the durability expected from a piston-driven AR-pattern rifle.
