Regulator nut backing out?

[Brendan]

I bought a thumb adjustable RVA to replace the regulator nut that was allen wrench adjustable for my mini-mag. However it moves around a little too freely. Could I just dab a little blue loctite on the threads to make it a little more immovable?

Wouldn't recommend loctite for that use, even if it's just blue. Add some teflon tape instead.
