Thread: Muzzle Breaks

You can buy the brake first, then supply it with the barrel to have it fitted, presumably not by yourself ?
Make sure the brake you get has the right pilot bore so that can be enlarged to give say a minimum 20 thou clearance ( 10 thou/side ) for the bullet. The brakes pilot bore enlargement step is done with the brake done up on the barrel, in the same lathe setup when the muzzle threads are cut. Then it gets BORED out to final size,
And get a brake with the largest thread size you can get away with, and still have enough of a shoulder for the brake to be screwed up against. Only if your barrel is like a pencil in size will u be forced to cut a really small thread.
Ya see lots of barrels with plenty of meat to fit a larger thread, but they have a stupid small 1/2" thread type.
I have fitted brakes to a couple of my rifles and have set them up - after modifying them - so the crown can be cleaned with the brake on. Seems a no-brainer to do that but some are supplied so you can't clean the crown without removing the brake. That's just another hassle plus the brake soon enough ends up not being indexed properly ( except the radial type ) as the threads wear.
