This is the Barrel from Our “SRC” Rifle, similar to our 16” M4 profile barrel but includes a Picatinny Rail Gas Block (attached onto the barrel using taper pins) to which you can mount a variety of accessory front sights. Or, leave it “bare” if you intend to shoot only with a scope. Barrel material is 4150 Chrome Moly Vanadium 11595E Steel, and it is Chrome Lined in both Bore and Chamber for long wear and ease of cleaning. Button rifling is 1 turn in 9 inches – right hand twist for optimum accuracy with a wide range of .223 / 5.56mm ammunition. A Black Manganese Phosphate finished is applied for protection against rust and corrosion. This barrel – machined in the M4 Profile – includes the Barrel Extension (with M4 Feed Ramps), Barrel Nut, Front Handguard Cap, Picatinny Rail Gas Block with Sling Swivel. The muzzle is threaded 1/2” x 28 T.P.I. to accept a variety of flash hiders or muzzle brakes.
