Well, I screwed up. I used Loctite 220 or 242 (one of the medium-strength formulas) on the allen head cap screws that attach the stainless sheet steel clamp to an anodized aluminum CMP Scout Mount. In hindsight, I should have used low-strength or nothing at all  When I decided to remove the mount, I was only able to loosen two of 8 or 10 screws. I managed to strip a couple others before I gave up. There's another clamp on the top of the barrel in a groove in the mount. By backing that off, I was able to slide the mount off the barrel, but I'd still like to get the screws out. If I can get them out, I can replace the screws, chase the threads and re-use the mount. I've tried heating the whole mount assembly in the oven and usine easy-out type broken/stuck screw remover with no luck. Any other ideas? For example, is there any kind of solvent I can soak it in that will dissolve the Loctite? The other option is to leave well enough alone, replace the two screws that came out and slide the mount back onto the barrel the way I got it off if/when I want to use it again. Technically, this isn't an AR or BIY thread, but I figured I'd get the best answers here. Essayons. |
Acetone? Did you use one of these? Let us know so we all can learn

Heat is the only way I know of to loosen loctite. Try heating the area with a hair dryer or heat gun and see if the screws will loosen. If you go to a propane torch you run the risk of screwing up the heat treat in the receiver. If that doesn't work, Pay a gunsmith to work their special brand of voodoo to get the screws out. ZM |

Thanks for the replies. Yes--the linked Sears product is exactly what I tried. Works great on broken screws, but not Loctited ones. I will try localized heat. Before I tried heating the whole thing in the oven in an attempt to soften the Locktite. The mount is no longer on the gun. I don't have to worry about the receiver--only the mount. |
| Lock-tite primer will loosen lock-tite if given enough time to penitrate, that means you have to spray it every couple minutes so evaparation doesn't stop process. Go to your local bearing and gear dealer and get thier booklet on lock-tite products, it will explain all the differant types and which to use for what and how much heat or type of solvent/primer to use. |
