as of 11/29/2022 10:38PM CST

This gunsmith service will permanently attach a muzzle device to your threaded barrel using the ATF- approved blind pin and weld method.  The weld will be finished with touch up paint. This is purely cosmetic and can be excluded at the time of the work order. 

When used with an appropriately sized barrel and muzzle device, this permanent muzzle device installation will take a short barrel out of NFA status and make it comply with the federal 16" minimum barrel length requirement.  This service may also be used for ban compliance in states that do not allow a threaded rifle barrel.

Note regarding appropriate muzzle device length:
Please include the correct length muzzle device for this service. Take thread overlap (roughly .6") into account when measuring the overall length of a muzzle device. We do not recommend using excessive shims/crush washers to meet length. Your work order will be delayed if the muzzle device does not have sufficient length.
14.5"(barrel length) - 0.6"(muzzle threads) + 2.6"(muzzle device overall length)=16.5"(legal length

14.5"(barrel length) - 0.6"(muzzle threads) + 1.6"(muzzle device overall length)=15.5"(NOT legal length

-Pin/Weld results may vary depending on muzzle device.
-We DO NOT pin/weld Titanium, Aluminum or Inconel muzzle devices.
-We DO NOT pin/weld Pistol Caliber(9mm, 45ACP, etc) barrels due to minimal amount of material on the muzzle.


Service Notes:
-IMPORTANT: We require the barrel, barrel nut, handguard, upper receiver, gas block/tube, muzzle device and shims or crush washer for this service.
-Ensure the proper length muzzle device is included for your barrel. Your work order will be delayed if the final length does not meet 16" OAL.
-Please do not time/install muzzle device to barrel prior to drop-off. If you want the muzzle device timed in a specific manner or orientation, please include detailed notes.
