I have installed a few FSB gas blocks but this is my first low profile install, it's a PRI low profile gas block.
I installed the gas tub and pin, lubed the inside of the gas block and the barrel and slowly slid
it in place on the barrel. made sure gas hole was properly aligned and gas tub was in place.
gas block fit was just snug, slight twisting as I pushed and it got there.
now I just have the set screws snugged in place nothing more. question is should I just tighten
the set screws untel it's firm as is.. or should I clean the gas block the brake cleaner or other and put any locktight on the set screws? if locktight what kind?
I do have blue 242 and red high strength. all suggestions are welcome.
if this has been discussed please post linky.
thanks new-arguy, cleaned it good yesterday and let it dry good overnight. will put red super strength on this evening.
my barrel had a small detent the alignment hole for gas tube and it was right were one of
the set screws needed to be so I used it and put a good amount og high strength red loctite
and tightened the screws a good amount.
