Timing a muzzle brake

[uga_fan]

Been a while since I timed a brake and I can’t remember ~ how much it will tighten down past hand tight to get to spec torque. Right now I’ve got it hand right and the flat top of the brake is ~ 10:30. I think that is ~ right, but wanted to run it by you guys before I put Rocksett on it.

A torque wrench is a minor investment to make sure it's done right. Especially if this brake is a mount for a can.

But generally...I want to see 10-15° of rotation past hand tight.

I'd need to see pics but you might need a shim kit to time it correctly

Is is for a SiCo ASR mount. I’ve got a torque wrench. It’s just been ~ 3 years since I timed a brake and I can’t remember how much past hand tight it will go to get into the correct ft/lb range. I had to use 3 SiCo shims to get it to hand tight @ ~10:30.

I’ll post pics this afternoon for you guys to look at.

If you've got a torque wrench, then stop worrying about how much angular rotation and just get it lined up and in the proper torque range.

Here is hand tight with 3 shims.

What exactly do you have clamped in the vise???

I clamp the barrel directly. Dont want that torque applied to upper.

If it won’t torque/clock up right just grind down yer crush washer with your finger pressure grinding the washer into a concrete slab in little circles until you have it lining up.

You don't use a crush washer on a suppressor mount.
