Direct impingement piston assembly in 5/8x24 thread pitch. Black finish. Compatible with suppressor-ready AR platforms.
This piston assembly represents a straightforward approach to converting direct impingement AR-platform rifles to piston operation. The 5/8x24 thread pitch is the standard for modern suppressor-ready barrels, making this component a natural fit for shooters looking to reduce bolt carrier group wear and improve reliability.
Piston-driven systems cycle more cleanly than traditional direct impingement designs. By directing propellant gases through a piston rather than directly into the bolt carrier group, you'll experience reduced fouling, lower operating temperatures, and extended component life. This is particularly valuable for shooters running suppressors or engaging in high-volume training sessions.
Proper installation requires attention to gas tube alignment and bolt carrier group compatibility. Consult your rifle manufacturer's specifications or seek professional gunsmithing assistance if you're unfamiliar with piston system conversions.
