Description

Build or upgrade your AR-15 with this high-quality PSA AR-15 premium mil-spec diameter buffer tube. This genuine Palmetto State Armory receiver extension provides a durable, precise foundation for your carbine stock, ensuring smooth buffer cycling, reliable function, and long-term performance under heavy use.

Crafted from premium 7075-T6 aluminum (stronger and more durable than standard 6061), this buffer tube features true mil-spec diameter (1.148″ outer) for compatibility with all standard mil-spec AR-15 stocks (like Magpul MOE, CTR, ACS-L, and more). The 6-position carbine-length design allows adjustable length of pull, while the internal dry film coating reduces friction for smoother buffer travel and extended service life. Black finish offers excellent corrosion resistance.
