Barrel and Muzzle Device

The 5-inch slim profile barrel is chambered in .45 ACP and constructed from 4150 CrMoV steel with a parkerized finish. The twist rate is 1:16 and the thread pitch is .578x28, which matches the included KAK Micro Flash Can. A black 5/8-inch crush washer is included. The direct blowback platform design addresses the .45 ACP cartridge in a pistol caliber build without a gas system.

Upper Receiver and Handguard

The Vertex Enhanced billet AR-15 pistol caliber upper receiver carries a black finish and is designed around the pistol caliber platform. The 4-inch slim-line freefloat M-LOK handguard is black with a full-length top Picatinny rail and M-LOK attachment points along the body for accessory mounting. These two components define the exterior structure of the upper assembly on this .45 ACP pistol platform.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. BCG and charging handle are not included. Verify compatibility with your specific .45 ACP AR-45 lower receiver and magazine pattern before use.
