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 and end cap. You will need your own bolt carrier group castle nut and receiver end plate to complete installation.
