The MK1 MOD 1-M line, revamped for 2018, features the PWS long stroke piston system. Internally, this line offers the tried and true system that PWS owners have grown to know and love. Featuring a free-float MLOK handguard, 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 Law Enforcement. With the fully forged upper and lower receivers, the MK1 MOD 1-M is a no-nonsense tool for when you need a high value option that is relentless and unstoppable.

For 2018 PWS brings back the original MK109 in 300BLK. The 9.75" barrel length provides excellent reliability with a range of ammunition and still function well, with or without a suppressor and without the need for an adjustable gas system. The MK109 makes a great choice as an SBR or a pistol.
