Oh the Horror! -STOP using BLUE Loctite!

[ssgross]

Now, it's not that I don't trust others who mount things on rifles, well M-A-Y-B-E it really don't trust, I guess, but if there is a scope or a scope mount on a rifle, I always remove and remount, just so I know its done right.

Me too. I used to curse the bubba under my breath that mounted before me, until I had a good friend bring over his brand new Remington 783, still in its box, with a scope and rings he wanted me to mount. The mount came already installed from the factory. Screws were either Torx or hex, I don't remember, but the first one required way too much force to remove, and boy ole boy was there a lot of loctite in there. the whole thing was a cruddy mess. I gently heated the others and they came right out with no issues. Underneath the blocks was enough loctite to fill a swimming pool.
I think purple 222 is all that is needed for small screws. Ive seen 242 in kits, and sold on some popular sites without differentiating except for the number.
I'll confess, I've used it (242) on scope mounts when it was all I had and they have easily removed months later to change mounts. The key is to use the right amount. I put a small drop on the wood stick-end of cotton swab, and then touch it to the threads. If your drop runs, you have too much. wipe off and try again. Same amount of 222 does the trick as well. I put neon red tape around the bottle of 271 (or 263) just to be sure I never make that mistake!
