Muzzle Brake help

[Ceej371]

Anyone know of someone that can install my muzzle brake on the cheap in/near the GTA? Don't have a barrel vice block to be able to compress the crush washer and don't wanna spend $150 for someone to spend 3 minutes installing it.

If you want to do it on the cheap, check with a plumper.

Or buy a jam nut. I think TNA carries 'em.

Can't you hold the action in a vise?

I'm just scared of all that torque transferring to where the barrel mates with the action. Or is that nothing to worry about?

Thought of that, just think it would look better with the crush washer (no gap between jam nut and barrel)

Two pieces of soft wood in a vice or rubber jaws. Tape the barrel if you are worried about the finish.

Barrels are usually torqued considerably tighter than a brake...

Muzzle brakes do not require much torque. As a matter of fact, if your installing this brake on a long barreled rifle of say 24+ inches, you really want to be cautious applying to much torque and stressing the barrel or even twisting it ever so slightly. It’s a brake, some folks run them hand tight.

In this case the brake has to crush a washer to get indexed correctly... sometimes almost a full turn...

You will not stress the barrel tightening a brake and it would be impossible to twist the barrel, I don't care how hard you torque it.

I missed that. Crush washers aren’t used here, brakes get indexed on machines.

“Impossible” and “No matter how hard” ? If accuracy is important to an individual, you can most definitely twist a barrel so that it’s accuracy fails. Some .30 cal lightweight barrels with OD’s of .600 are very susceptible to deformation. To each their own Guntech, just letting the OP know some possible concerns with over torquing brakes after many years of manufacturing and installing.

This. You do not need a barrel clamp or vise to install.

I have been smithing for a few years... I know I can not twist a barrel beyond it's elastic ability tightening a brake.... not even a skinny barrel with a 1/2x28 thread. What kind of equipment would one use to actually cold twist a barrel beyond it's elastic abilities?

I normally index brakes by machining but I had one customer who wanted to use a crush washer but didn't want to do it himself... I used a 15 inch Crescent Wrench on the brake holding the barrel solid. The crush washer crushed as designed without much effort and the brake required about 1/2 a turn.
