Upper Assembly and Barrel

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 build.

Suppressor Ready Threading

This kit 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 build. Compatibility and secure mounting should always be verified before use.

Lower Parts Kit and Buffer System

This kit includes a complete Mil-Spec AR-15 lower parts kit along with a Mil-Spec 6-position buffer tube, an 8 oz 9mm buffer, and a standard carbine recoil spring. A Mil-Spec receiver end plate and castle nut round out the rear hardware for this build. These components cover the core lower completion parts included with this kit outside of the lower receiver. Lower receiver not included.

SBR Ready Configuration

This kit ships without a brace or stock. It is intended for customers who are selecting their own final stock or brace setup based on their specific build plans. The right choice depends on individual setup needs, so the brace or stock is left to the buyer rather than included here. This keeps the kit flexible for builders finishing their configuration according to their own compliant setup.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. Ships without a brace. Do not attach a stock unless compliant with applicable laws. Verify compatibility and secure mounting before use.
