Design and key features

This MK1 Mod 2-M lower is multi-caliber rated, giving builders flexibility for common AR chamberings without needing a dedicated lower per caliber. The receiver is machined to accept most mil-spec upper receivers and standard AR-15 magazines, simplifying parts selection and ensuring compatibility with a broad aftermarket ecosystem.

Ambidextrous controls

PWS engineered this lower with fully ambidextrous controls so left- or right-handed shooters can work the safety and magazine release with confidence. For tactical operators and range enthusiasts who demand intuitive control placement, the ambidextrous layout reduces manipulation time and improves ergonomics.

Receiver tension screw

A standout mechanical detail is the integrated receiver tension screw. This allows builders to eliminate rattle between the upper and lower receivers, tightening the interface for a more solid feel under recoil and during rapid manipulation. Small adjustments here translate to a firmer, quieter platform.
