What wrench works with mounting this thing?
Appears to be 21mm wrench but the wrench flats are only .21" and on a host with a thicker dia bull barrel, can't use a wrench that overlaps.

Can't find this info anywhere.

I had to make a wrench for a bull barrel rifle to fit a YHM suppressor mount.
Standard wrenches were not thin enough

I have run into this before. I actually found some thinner ones at Walmart. Took what. I had and just compared them.

I have no problem doing the 5.56 brakes, but the issue is with the 7.62 one.

The wrenching point isn't as open like on 12 and 6 o'clocks of the 5.56 brake ports, but behind the 51 teeth on the 7.62

(I got two because one of the barrels I've yet to deal with is a Kel-Tec RFB, and it has a tight OEM muzzle device/jam nut combo with very little clearance width on the flats of either. )

thanks, after you check them out, would you share links?

Also, how do yall recommend supporting a bolt gun? Seems like all I can think of is the barrel in a vise with some protective jaws

I ordered this set of Super Thin Wrenches from Amazon and they've worked great.
