Rather than cut up a mop handle. I keep a couple pieces of 1" dowel for just this sort of job. montana Wrote:I use green loctite"620" between the barrel and gas block block journal for proper seal.... Using a torch to break down any loctite thread lock adhesive is a very simple process...Not so simple sometimes. I once used a green "penetrating" version of LT (labeled as a Permatex product) under a gas block. This type of green LT is designed for post-installation thread treatments, etc. Flows like water, wicks into any void. Anyway, I applied it under a Troy low-pro gas block, a set screw type, on a GMR stainless barrel. I figured it'd be good for "good measure" for holding the GB in place and to help with sealing.
About a year later I decided to change the handguard, and that required changing the barrel nut. You would not believe the hassle I had removing that GB. Long story a little shorter, it took a couple minutes of heating with my MAP gas torch and active pounding on the GB before it even started moving. I don't know how hot I got the GB but I could see heat ripples in the air from it. Wrecked my GB, BTW. You can see how scorched it got in the pic below And how mashed it got at the top. And even after the GB came off completely and I applied the a heat gun to the remaining residue, the hardened LT was was extremely difficult to scrape off.
Can't recall if I tried getting the residue off with Goof Off though, darn it. And it was in the cabinet right below where I was working. Probably won't dissolve it once LT's baked on. Although, according to some people, that's impossible. LT can only melt! I discovered different though. Never again will I use that stuff for this kind of application.
