The heart of our Competition Ready Carbine platform utilizes a Lilja AR10740 416 stainless barrel with a 1-11 twist. The barrels are threaded for and furnished with a pinned barrel extension with proper headspace, gas port hole drilled and finished with a target crown at the muzzle. The muzzle end is also threaded 5/8″ x 24 TPI to accept standard 30 caliber suppressors or muzzle brake devices. Currently our competition ready carbine are offered in a 18″, 20″ and 24″ model on our AR10 platform system.
