The PWS MK1 Mod 2-M solves the left-handed shooter problem by including fully ambidextrous controls – both magazine release and bolt catch work from either side without adapters or compromises. This lower works exceptionally well for left-handed shooters, mixed-hand shooting positions, and training environments where multiple shooters use the same rifle. What sets the MK1 Mod 2-M apart is the complete ambi package at the factory level – you get proprietary PWS ambidextrous components that are built into the design rather than bolted on, plus the Enhanced H2 buffer and ratchet lock castle nut system ensures reliable cycling and secure retention under hard use.

The PTFE-coated trigger provides smooth operation and corrosion resistance, while BCM furniture delivers proven durability from a trusted manufacturer. The integrated trigger guard and lightweight design reduce bulk without sacrificing strength.
