PWS is the designer and manufacturer of the MK1 and MK2 series rifles and uppers in addition to a complete line of flash suppressing compensators such as the FSC556, SM556, FSC30, and more. PWS develops items based on real world requirements with the goal of redefining accuracy and performance in the piston-driven platforms.

A model developed after the M4 pattern rifle, the PWS MK114 Rifle has quickly become the crowd favorite for those wanting a compact package without the NFA paperwork associated with shorter barrels. The MK114 retains lethal capability out to 500 meters with varying types of ammunition and boasts a permanently attached FSC556.

Utilizing the proven system originally designed for the MK107, the MK114 uses a mid length gas piston system. The operating system, designed after the venerable AK-47, features a long stroke fixed operating rod design with an adjustable gas block, 15 handguard and free-floated barrel.

The handguard features the VLTOR KeyMod System which comes standard with two 2 sections of 1913 rail as well as a continuous 1913 top rail.

Understanding the importance of an ultra-reliable package that is light as possible, mil-spec forgings are used for the upper and lower receiver. Additional features include the BCM GUNFIGHTER charging handle, the PWS enhanced buffer tube and an ALG Defense QMS trigger. The rifle is rounded out with industry leading features such as Magpul MOE grip, MOE stock, and MBUS2 sights.

Available as a complete rifle or as a complete upper receiver.
