Looking for a gunsmith in Southern NJ to swap out muzzle devices for me. I recently purchased this upper from Springfield and I want muzzle brake removed, and this linear comp installed, properly timed with a crush washer. I do NOT want the comp pinned. #1 it’s an upper and not a firearm, and #2 I intend to put it on a fixed mag lower anyway. My local gunsmith is a great guy and I give him business all the time. But he is overly cautious and won’t let any upper leave his shop without a pinned muzzle device.

Do it yourself?

As long as you have appropriately sized wrenches it should just be unscrew → screw on → tighten to desired position/clocking.

Not sure where in S.jersey you are but, Ive used Round 6. Had a barrel change and some compliance work done. Quality work and fair pricing.

Not a good idea without a barrel vise. The factory torque those things on pretty good and some even use rockset.

You are welcome to use my receiver block if you want to do it yourself. Located in Mt Laurel Just soak muzzle in warm water or get some steam on it and it should come off.
