Hey guys,

I have a 16" upper with a Pinned and welded muzzle brake from when I was in a Ban state.  The gunsmith that I had pin and weld the muzzle brake, did not install the brake with the timing washers from surefire and just arbitrarily pinned the brake slightly mis timed.

Will this cause an issue in the long run?  I haven't really put many rounds through it, but I'm wondering if it will be an issue now that I'm trying to run a surefire suppressor on it.

I'm wondering if its worth it to try and grind and remove the brake, and put a new one on (not permanently attached this time.

Thanks

If you now have a stamped lower, definitely grind the weld out, remove brake, and install new muzzle device unpinned on stamped lower. Peace of mind is a good thing

Very true,

Its also an older surefire brake and my new Suppressor doesnt lock in, which is really why I want to switch.

Definitely do it. Considering the above I wouldn't even try to salvage the old brake, and just grind it out, remove pin, spin her off.

Would drive me crazy.  Its absurdly easy to perfectly time a muzzle brake. I put a  level on a flat spot on my rail, and a piece of straight cleaning rod on the flat of my muzzle device.  Torque until they are parallel.  Done.

Now that you have cans and it doesnt work anyways......send that brake to the trash can.

Apart from aesthetics, a slightly mis-timed muzzle brake isn't going to hurt anything. A suppressor times to the brake itself with its indexing pin and notch.

It's up to you if it is worth the cost of getting a new brake. I would not reuse the old brake.

I use my socom can on a 556k brake, works fine. It just doesn't have a tab that fits in the slot that indexes it.

That said, on a sbr I would unpin the brake on general principle.
