Attach a muzzle device permanently to bring the OAL to 16.0" , or AWB Compliance. This is the pinning service only, with the option to remove an existing pin and welded muzzle device. This price does NOT include threading the barrel or a muzzle device.
Please be sure to double check your measurements before sending your parts in.
Barrel length + muzzle device length - 0.625" (thread overlap) = Overall length
Be sure to send your barrel nut and gas block as these cannot be installed after a pin and weld. Please also send the appropriate shims for your muzzle device.
We do NOT pin and weld any aluminum muzzle devices.
