For use in States with restrictions on flash hiders, we developed this 20” government profile barrel with a pinned & welded on A2 Birdcage type Muzzle Brake. This is perfect as a replacement barrel, or for that service rifle build you’ve been planning. 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 7 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 is machine turned under the handguards to offer the lightest weight possible. It includes the Barrel Extension (with M4 Feed Ramps), Barrel Nut, Front Handguard Cap, and standard A2 Front Sight Base with Sling Swivel. Note: any attempt to remove the A2 Birdcage Muzzle Brake will result in barrel damage.
