Dude, seriously, do NOT use loctite on your HALO. That's just dumb.

I crank mine on with hand pressure and it has NEVER come loose.

When it gets stuck, there is an EASY way to remove. Heat up the collar a bit with a propane torch, then unscrew the collar while wearing heat resistant gloves.

This is NOT the same as shooting it to heat it up. That heats the entire assembly from the inside out, so everything is expanding.

When you heat the collar ONLY, only the collar will grow.
