Items are used and show wear. Picture is not reflective of condition. These are a military trade-in we received and quantity is very limited, units were tested for function.

UTM’s Rifle and Carbine conversions and conversion kits are designed and engineered for the upmost in safety, in-service reliability and maintainability. The conversions and kits are easy to install, typically a simple exchange of the manufacturer’s Bolt and Carrier Assembly. UTM conversions adapt the host weapon to fire UTM ammunition with the feel and function of “live” ammunition. With the exception of the HK-416 and SIG 516, which require their own conversion, the UTM standard rifle bolt conversion will function in any right hand ejecting, direct impingement or gas piston M4/M16/AR-15®.

UTM bolts are designed with an off-center firing pin for safety. They will not contact the primer of 5.56 live rounds. For safety, we recommend using painted or designated magazine types for UTM ammunition only, and to have your equipment double checked by at least one partner.
