Overview
The PWS MK1-M2-LWR MK1 MOD 2-M Stripper Lower Receiver is a stripped lower designed for the AR-15 platform, crafted from durable 6061-T6 aluminum. Its ambidextrous controls enhance usability for both left- and right-handed shooters, making it a versatile choice for builders. This lower receiver is most commonly found in builds chambered for .223 Wylde, making it ideal for those looking to maximize their rifle's versatility with different ammunition types.

Builders have been adding it to their builds on GunPartPicker since February 2026. All time, it ranks #358 of the 1,001 lower receivers builders have added. Builds with this lower receiver are nearly all chambered in 5.56 NATO and nearly all AR-15.
It was hard to find in August 2026, in stock on only 9 of the 20 days we checked, and today only Palmetto State Armory has it in stock. The best price drifted down from $319.95 to $299.95 over August 2026 without a real sale. Buying today, the lowest price is $355.99 at Palmetto State Armory, above August's low of $299.95, so a better deal may come back.
