Primary Weapons Systems Mk1 MOD 2-M Complete Lower Receiver – Kodiak Brown Anodized
The Primary Weapons Systems MK1 Mod 2‑M Ambidextrous Complete Lower Receiver represents the next evolution of user‑focused AR‑15 design—engineered entirely in‑house by PWS for shooters who demand adaptability, durability, and premium ergonomics. Built from 7075‑T651 forged aluminum and finished in a rugged Mil‑Spec Type III Class 2 hard‑coat anodize, this lower delivers exceptional strength and long‑term reliability. The striking Kodiak Brown anodized finish paired with B5 Systems furniture gives the Mod 2‑M a refined, modern aesthetic.
Designed around true ambidextrous operation, the Mod 2‑M lower features mirrored controls that allow seamless manipulation for both left‑ and right‑handed shooters. The Mil‑Spec enhanced trigger with PTFE coating provides a smooth, consistent pull, while the PWS Enhanced Buffer Tube with ratchet‑lock castle nut and integrated QD mount ensures a rock‑solid, rattle‑free setup. The included PWS H2 steel‑body buffer further enhances recoil management and cycling reliability.
