The barrel is a 10.5 inch 5.56 NATO front sight base barrel that uses a carbine length gas system. It features an A2 style front sight base with a USA made steel A2 front sight post, plunger, and spring. A carbine length stainless steel gas tube is included. These parts give the barrel a traditional fixed front sight setup.

Drop-In Quad Rail Handguard and Colt Delta Ring

The M4 carbine length drop-in quad rail handguard measures 7 inches and comes in black. It offers Picatinny rails on all four sides for lights, lasers, and grips. A Colt AR-15 delta ring is included for the drop-in handguard setup. The quad rail gives the classic front sight base layout plenty of accessory space.

Tanker Style Muzzle Brake and Crush Washer

The kit includes a black tanker style three port muzzle brake. It is threaded half inch x 28 with a 0.3 inch bore diameter. A half inch black crush washer is included with the brake. The tanker style gives the front end a short, classic look.
