PWS MK116 Compound 5.56 Rifle With Fully Ambidextrous Lower

The best of both worlds.


This new offering from PWS will give you the best of both worlds. You will get the heavy duty, hard use, more true to milspec complete upper receiver paired with their new fully ambidextrous lower receiver. The PWS MK1 MOD 1-M upper features the PWS long stroke piston system, and is favored for it’s extremely robust nature. Internally, this line offers the tried and true system that PWS owners have grown to know and love. Featuring a free float 15″ M-LOK® handguard, and forward assist, the the MK1 MOD 1-M line is a go-to for not only civilians, but also Law Enforcement. With the fully forged upper the MK1 MOD 1-M is a no-nonsense tool for when you need a high value option that is relentless and unstoppable.


PWS MK1 Mod 2 lower receivers are one of the only forged, fully ambidextrous lowers available on the market today. The new MK1 Mod 2-M lowers feature an ambidextrous bolt release and mag release like before, but now comes with an ambi bolt hold open as well, giving you full true ambi features. Held to tight tolerances and quality controls, these lowers are a perfect way to get the strength of a forged lower with the aesthetics of a billet. Finished off and anodized per Mil-Spec (MIL-A-8625F) which is a Type III Class 2 hard anodizing process. Machined right here in Boise from proprietary forgings made specifically for PWS!


The MK116 Mod 1 upper has a 16.1″ barrel, with a mid-length long stroke piston. It comes with a complete bolt carrier group, Radian/PWS Raptor charging handle, and a Triad 556 compensator.
