    Be thankful they actually put Red Loctite on your Gas Block Set Screws

    I've had ADCO do various things for me over the years, mostly pinning gas blocks and FSBs. He does a good job, but I've always been struck by the amount of cosmetic scarfing of the block and surrounding barrel finish. Had a similar experience at Rainier. I only use blue loctite on gas block screws, but I would never trust a gas block that wasn't pinned. That's me, anyway. YMMV

    I would rather drill out the set screws that have red Loctite on them than use heat, but that is just me.

    I removed my set screw gas block from my BCM 18" barrel. Two of the three screws came out without issue. Prior to drilling I tried heating the screw with a large MAP gas bottle. That screw would not break loose for the life of me. I bent and broke a couple of allen keys trying. I even tried smacking the screw to shock it loose. The last screw forced me to remove it by drilling. It was a total PITA but doable.The old gas block is also salvageable. I ended up replacing the gas block with a BCM part anyway.

    I was talking with a good friend of mine that's an engineer. He recommended this to help narrow the heat to the screw specifically.

    Im glad it was secured, but wish it were a little easier to remove. I would rather send it off and let someone else do it properly thn risk damaging it myself. I was so frustrated after messing with it for two days in a row that I almost just bought a new 11.5" barrel for the new gas block.

    Have you tried something like an adjustable Weller Soldering Iron turned up as hot as it will go, with the tip placed directly into the Screw Head?

    No need to use crazy heat and stuff. Get this and follow the instructions. If it doesn't work, do it twice. I use it all the time and it works. YMMV

    IG,

    I don't know if this will work on this gas block. It seems as though the Loctite applied to these set screws is some combination of adamantium and minotaur semen. I may pick up a bottle to try though before I send it off.

    Thanks

    I am very familiar with how that block was installed. I also know what Loctite they use. Uncure breaks down cyanoacrylate which is the active ingredient in Loctite. I have used this stuff for about the last 6 months and it has yet to not work for me. YMMV

    A BIG thanks in advance for the hassle you have just saved me when doing this in the future.
