The PWS MK1 MOD 2-M Stripped Lower Receiver (brand part no. MK1-M2-LWR) is a multi-caliber AR-15-compatible lower forged from 7075-T6 aluminum and hardcoat anodized black per MIL-A-8625F Type III Class 2. Primary Weapons Systems ships the MOD 2-M with its proprietary parts included — a left-side magazine release, bolt catch spring and screws, tension screw, bolt release lever, and bolt release through-pin — so the receiver’s ambidextrous-friendly controls build out correctly from the start. PWS earned its reputation with long-stroke piston rifles built for high round counts, and the same manufacturing standard carries into this receiver. Among rifle lowers, the MOD 2-M favors builders who want a premium forged foundation with enhanced controls.
