Short Buffer System

Our short buffer system transforms your AR pistol into an even shorter and more compact gun. New internals, new features, and a new look. Whether you're looking for a buffer replacement for your pistol caliber carbine, or your regular 5.56, 300BLK, or 7.62x39 AR, we have a short buffer system for you.  We're breaking down the internals based on the two types of bolt carriers: integrated and non-integrated bolts.  Integrated carriers have the bolt face machined directly into the carrier (common blowback 9mm, 40S&W, 45ACP, and 10mm carriers).  Non-integrated bolts cover your typical 5.56, 300BLK, 7.62x39, and the CMMG radially delayed blowback calibers.  

The 3.5 version will not require any modification to your carrier or end plate.  Just install the short buffer system in place of your standard buffer, spring, and receiver extension.

Check out our collection on this page and contact us at 239-848-6757 if you have any questions about product availability or use.
