SVI4ME Posted September 19, 2012 Report Share Posted September 19, 2012 I have an 18" Blackhole bull SS barrel and I will be installing a Big Cooley brake/comp from JP. What is the best way to install this? Crush washer, nut or Loc tite. Both are stainless in color.Thanks in advanceRob Quote Link to comment Share on other sites More sharing options...
Jgun Posted September 19, 2012 Report Share Posted September 19, 2012 Unless you have access to a lathe or are prepared to pay someone with one to remove the correct amount of material from the back of the JP brake so that it times correctly, IMO you're better off with shimming the comp on the barrel than using a crush washer. I think you can buy the shim kits from Midway and Brownells. Then all you do is stack them until the brake is oriented as you's like. Some people choose to cant them slightly to counteract the opposite torque that is caused be the bullet applying pressure on the barrels rifling. If you go with the shims you can try it both vertically orientaed and canted to see which you prefer, and then I would use red locktite on it.

Matt.Cross Posted September 20, 2012 Report Share Posted September 20, 2012 What Jgun said, shim kits or peel washers. Crush washers are a nightmare. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted September 20, 2012 Report Share Posted September 20, 2012 Have it welded on, then smoothed out on a lathe. It'll look clean, with continuous lines and curves... Or get lazy and shim it ;D <thumbsup> Quote Link to comment Share on other sites More sharing options...
washguy Posted September 20, 2012 Report Share Posted September 20, 2012 What Jgun said, shim kits or peel washers. Crush washers are a nightmare.I just got a shim kit from Spikes yesterday....they come barrel /thread specific .....and the package gives you rotational values of the shims....kewl deal ...pkg has has a thick, a not so thick <laughs> and a bunch of very thin shims....clocking a comp/brake is an azz whooping...because by the time you get to this stage that means the gun's ready to go....and so are you <thumbsup> Wash Quote Link to comment Share on other sites More sharing options...
