TRIARC Systems Mil-Spec Buffer System Kit – Hard Coat Anodized With Optional Dry Film Lube

The TRIARC Systems Mil-Spec Buffer System Kit is designed for AR-15 carbine-length platforms, providing core components with precision manufacturing and enhanced materials. The 6-position buffer tube is machined from 7075-T6 aluminum and finished in either Type III Black Anodize or Type III Hard Coat Anodize with Dry Film Lubricant applied to internal and external surfaces. This solid-film lubricant reduces friction, resists corrosion, and maintains performance under high-load and high-temperature conditions.

The kit includes the TRIARC Enhanced Mil-Spec buffer spring, made from chrome silicon for heat resistance and extended service life. A high-carbon steel castle nut and steel end plate with sling socket are included for secure installation.
