Install Muzzle Device with Crush Washer



Installation of various muzzle devices using a Colt crush washer.   Perfectly timed to top dead center.   We will install Colt A2 flash hiders or other customer provided muzzle devices.  No wrench marks on your muzzle device.   Installation uses precision custom wrenches in our shop.

Barrels are held by the barrel themselves during muzzle device installation in special padded fixtures.  We do not use barreling spud rods for muzzle device installations.  This puts stress on the barrel index pin.

This service is not for muzzle devices requiring shims for suppressor applications.   We offer that as a separate service.

Customer provided muzzle devices must be new or near new condition and must be free of wrench marks.

We do not perform permanent pin and weld installations.  We do not perform removal of permanently pinned and welded installations.

Removal of existing muzzle devices which were installed with thread locker or any other non-standard method will be charged at a higher rate on an individual basis.

We can also install Colt A1 or 3-prong flash hiders with split washers for retro or restoration projects under this shop service.

Includes return shipping of your barrel.
