Blue!!!! If you use Red, you will risk stripping the set screw if you ever need to remove it again. Heat will soften Red, but with a small screw like that, you really don't have a lot of leverage on the small screw head to break it free, even if the Loctite has been softened by heat.

I agree,blue(or 242 I believe),is the only one to use unless you're locking down a problematic comp.Red will come off without heat,but it needs to be fasteners larger than roughly 3/8" diameter.I haven't used the green,but heard it's good.It is self wicking,so after the item has been adjusted or set,the green will wick into the threads to lock it.It is minimal strength however.
For what it is worth in the event you can't find the correct lock tite you can use some of your wife's or girlfriend's clear nail polish. I use it on my set screws and scope mounts and have not lost anything yet. I like low tech solutions.

The nail polish sounds interesting. I'm wondering though if it would hold up to cleaning solvents as well as Loctite. I sure don't plan on adjusting the sight too often, and I don't want to keep having to apply it after each cleaning.
As for the nail polish I have used it on all my sight set screws and have not had one loosen up. The nail polish is easy to break loose when you need to change something. I use Hoppe's #9 and Shooters Choice as cleaning solvents.
As for coming loose, the only time I have seen it come loose on scope bases and rings was on a 416 Rigby. Just used a little more.
oldcolt,could be.I don't have a breakdown handy.There might be 2 greens though like the 2 reds?I know there is a low strength,self wicking though.I'll post the strengths when I find my info.Brownells carrys most of the Locktites,but I think not all.
