Service to cut and re thread your IWI Carmel Barrel, which includes opening the gas port to the appropriate size based on its new length. Several options available, be sure to check selections. Send in your pulled barrel with a copy of the order confirmation, or notate the order number somewhere inside the box.
The 12" cut brings the muzzle device pretty much flush to the end of the handguard. If you are wanting to run a suppressor, we recommend at least a 12.5" to accommodate various QD mounts.
