A model developed after the M4 pattern Upper, the PWS MK114 Upper 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.
