Good morning all! Looking for advice from those who have ever placed a compensator on their gun. I installed an Armory Craft compensator on my Sig P226 this weekend using the instructions video on the Armory Craft website. Tightened down the two set screws as well as I could using the tiny wrench provided and used blue Locktite in the threads. When I took it to the range it shook loose somewhere around 80 or 100 rounds. I talked to the range master about it and he said following the instructions on website is not good enough. I need to get a gunsmith to grind dimples into the barrel so the set screws have someplace to securely fit into. Anyone else do this, and if so how well did it work? Any other way to solve the problem? Thanks!
I am not sure if this will solve your problem . I have only used the threaded comp’s with crush washers … I would use Loctite 272 it is for high heat … Again not sure if this will help …
I’m not sure if Blue Loctite is a good option for anything close to the muzzle. It easily breaks at 300F, which is exact a temperature of the muzzle after several shot taken.
I stopped using Blue on anything close to the barrel, once I lost screws on handguards and screws used for front sight mounting.
I’d recommend Red Loctite for high temperature application (up to 500F).
I’m not familiar with comps on pistols but I would hazard a guess that any and all screws should be torqued with a torque wrench to spec specified by the manufacturer and the appropriate threadlocker should be used. What torque spec and threadlocker or similar was called for?
As above, I wouldn’t think blue is the thing to use where heat is involved. Red ‘permanent’ more likely.
Hi Nathan. The information and instructions on the compensator manufacturer’s website did not specify how much torque should be used. Wish it did. It sounds like everyone is voting for the red Locktite. The manufacturer’s instructions did say to only use the Locktite on the set screw threads, and not on the threaded barrel itself. Not sure why this is. Obviously I don’t want any Locktite seeping over the end of the muzzle and getting into the barrel. Other than that not sure what the problem would be.
