The PSA PA‑10 Gen 3 is a generational update to Palmetto State Armory’s AR‑10‑pattern semi‑automatic rifle built around the .308 Win/7.62×51 NATO cartridge. Designed for durability and improved performance, Gen 3 models feature forged receivers, adjustable gas systems, a mid‑length gas setup, free‑float M‑Lok handguards, and enhanced components like a robust bolt carrier group and quality fire control parts. This platform is suitable for general‑purpose shooting, target work, and duty‑style roles and accepts standard AR‑10/LR‑308‑pattern magazines and many compatible parts.
