The Kentri 3.5 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.
CMMG Banshee 9mm radial delayed blowback BCGs are also compatible with
this model. An M4/M16 bolt carrier is recommended for reliable function
(lightweight carriers may lead to malfunctions).
The Kentri 3.5 (KTR35N) includes a
tube, dual-spring recoil assembly, end cap, and castle nut. You will
need your own bolt carrier group and receiver end plate to complete
