This includes cutting/crowning as well as threading. Threads will be concentric to the bore. Do NOT send the complete rifle. – If you want the barrel shortened note length in the comment section at checkout. When barrels are cut, they are all measured from a closed bolt face as the only standard measurement we use. Send just the barrel assembly. Do NOT send the barrel attached to the receiver.
SCAR barrels are too skinny and have no shoulder. If you want to install a muzzle device that requires timing we recommend this service. This service includes a tapered shoulder added to mount/time muzzle devices. ADCO will ONLY install timed muzzle devices on SCAR barrels that have this shoulder.
5.56 barrels will be threaded 1/2×28
7.62 barrels will be threaded 5/8×24
