Product Description

The shortest available option in the PWS MK107 MOD 1 rifle was the first firearm developed. Known as “The Diablo”, the MK107 was designed to replace MP5 style weapons. Used heavily in law enforcement and SWAT settings, it has been a vital part in the growing use of SBRs as patrol rifles. The PWS MK107 MOD 1 rifle features the long stroke piston system. Internally, this offers the tried and true system that PWS owners have grown to know and love. Featuring a free-float MLOK rail, forward assist controls, and a more true to mil-spec design, the MK1 MOD 1-M line is a go-to for not only civilians, but also LE. With the fully forged upper and lower receivers, the PWS MK107 MOD 1 rifle is a no-nonsense tool for when you need a high value option that is relentless and unstoppable.
