The AAC Rate Reducer Buffer slows the rate of fire by 50%, saving you ammunition and more importantly, increasing your accuracy and control. This easy-to-install, machined-steel recoil buffer also helps to reduce recoil and virtually eliminates muzzle climb, providing the shooter with enhanced controllability in sustained, full-auto fire.

The buffer has been used but is in EXCELLENT condition. The price of $75 SHIPPED includes the stainless steel buffer w/tungsten, buffer spring, plus two (2) extra buffer springs, insertion/extraction tool and instruction booklet.
