Pantheon Arms has recently launched their latest offering in efforts to make the AR-platform more compact with the Kentri 3.5 AR buffer system that is designed to replace your existing carbine length gas system.

Pantheon Arms states “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).”


Tube Diameter: 1.3″

Materials: 7075T6 Aluminum, Stainless Steel, Alloy Steel
