Full description and what we offer
Adams Arms engineered the first and only patented retrofit piston system for the AR-15 platform. The difference is real: piston guns run cleaner, cooler, and with less maintenance than traditional direct impingement rifles—reducing cleaning time from 2 hours down to 2 minutes.
Piston guns are preferred by nearly every fighting force in the world. The old DI systems are on their way out and piston systems will be the standard of the future.
The math works out simple: less carbon buildup means less wear on your rifle, less time at the cleaning bench, and more time actually shooting. You're also reducing heat stress on components that typically fail first.
Adams Arms offers three tiers:
They make complete rifles, pistols, uppers, complete upper assemblies, piston kits, and lower receivers. Available in rifle and pistol configurations from 8.5" to 18" barrels.
Adams Arms inventory is now managed by Alexandria Pro-Fab. Check their main site for current stock and availability.
