Threaded BBL Cap Loosening



Log in to see fewer ads
I have a Kidd Supergrade with 20 in., fluted & threaded bbl. My initial testing showed that the rifle was more accurate without the optional muzzle brake installed, just having the threaded cap installed seemed to make it slightly more accurate.

However, recently I've found that the threaded cap is loosening after around 50-100 shots and it's POI does seem to shift in a more-or-less regular pattern. Perhaps as the bbl heats up, or perhaps as the thread cap loosens?

Anybody have any observations concerning those threaded barrel end caps? Should I lockTite it? Crank it down tighter than finger tight with a strap wrench? Give the muzzle brake another shot? Experienced thoughts and comments are welcomed. Thanks -S2

All muzzle devices loosen up. Try a dab of grease and give it a good hand tightening

They make a version of lock-tite weaker than blue, for less aggressive grip. You could use that.

This^^^

LocTite makes a blue version in a stick applicator that does the trick perfectly without ever truly “locking”

One wrap of TFE pipe joint tape - Teflon tape- will do the trick. No need for Loctite.

I use a little clear nail polish on mine. Used it for years on trigger screws when comp pistol shooting and never a problem.

Thanks to all, I'll give that blue-stick LocTite a try with the muzzle brake. -S2
