The Ronin Competition upper assembly pairs a 6061 billet pistol caliber upper receiver with a Gashkin 8 inch barrel and a 7 inch free float M-LOK handguard. The barrel is made from 4150 CrMoV steel with a nitride finish, cut with a 1-16 twist rate. The handguard is free float in design and includes a partial picatinny top rail. Together these components make up the front end of this 45 ACP AR-15 pistol upper.
This upper includes a Hughes Precision thread adapter that converts the 578x28 barrel threading to standard 58x24 threading for compatible muzzle devices and suppressors. This threading option is intended for buyers planning to add a suppressor to a 45 ACP AR-15 pistol build. Compatibility and secure mounting should always be verified before use.
