Superior construction, lower maintenance, absolute reliability, and performance. PWS is a company that continues to innovate with each product they bring to market. Always with their customers in mind, they are constantly evolving to ensure they are delivering unmatched performance that works every time.

The PWS MK1 MOD 2-M line features the PWS long stroke piston system. One of the core features that distinguishes PWS from every other AR platform on the market is their Long Stroke Piston System. It offers the reliability of an AK- style piston system with the intuitive function and ergonomics of an M4/M-16. The easy to adjust 3-position gas setting allows the user to quickly optimize performance with or without a suppressor.

While the internals remain the same as other tried and true PWS lines, the MK1 MOD 2-M offers a variety of features exclusive to this line.

Starting with patent pending PicLok technology on the free float handguard, users can mount either Picatinny or MLOK accessories on the front of their firearm.

With fully forged upper and lower receivers, the craftsmanship of PWS products is easily recognized and stands out from any comparable products.

Innovative design, eliminating forward assist, a flared mag well and built-in trigger guard, among other unique features, the MK1 MOD 2-M takes high end firearms to a new level. Sleek, compact, and ready for anything, the MK1 MOD 2-M is sure to please esthetically and impress in-action.
