Extended AMD 65 Muzzle Brake 4.3" long is made from 4140 steel to bring the barrel length of the rifle to 16". Threads are 14-1 left hand. These were made just like the original machined brakes where there is a cap that screws into the front to create the chamber. Since these are black oxided which uses an acid bath it may be necessary to clean the end of the brake due to the chemicals not being neutralized in the threads. 6.9 oz.
These are made in USA!
