Deal Details
Pantheon Arms Kentri 3.5N AR-15 Short Buffer System Black Oxide/Anodize. 5 is a direct drop-in replacement for your traditional carbine buffer buffer spring and receiver extension extending just 3.5 inches from the rear of your receiver. No modifications required. This specific model is only compatible with carriers that use a non-integrated bolt (traditional blowback pistol caliber carbines will have different internals coming soon). Compatible calibers include 5.56x45mm .300BLK and 7.62x39mm.
