Which color loctite do you recommend for installing scope bases (weaver style bases on a rem 700)? I have a choice of red,blue and purple available locally. thanks

Fortune favors the bold.... and the armed.

All I feel is....Recoil!

The blue will allow you to remove the screws later if it ever becomes necessary, but will hold secure under recoil. I think the red is semi-permanent and I have no idea what purple will/won't do.

...Blue is correct.

...With red, you will have to lightly heat screws in order to remove them.

Blue is the best for keeping on hand for most gun uses. Red is semipermanent and requires heating with a torch for removal.

Purple is a lower strength than blue, used for small setscrews and such.

I use red ALOT. It holds better and if you decide later to remove them a little heat allows removal.

Please make dang sure you have a good thread engagement count on the screws. It takes 4 to 4 1/2 threads to secure it. I got hit HARD with a scope, mount, and ring assembly right between the running lights last week. It cut me pretty badly. The screws that came with weaver mounts could be too short, mine were. My 375 H&H encore barrel still had the screws with blue loctite firmly held into the mount. They stripped out all four screws from recoil. OUCH

Thankfully; I am now still ugly with an additional scar for my half-century of living.

I will use EPOXY glue on the base and barrel and blue loctite on the threads when I get the new screws.

I am a practicing Curmudgeon, someone that hates hypocrisy and pretense and has the temerity to say so.

bpost -- might try a TSOB mount from SSK Industries on the 375. It will hold. Made for the big kickers.

It's more important where ya hit 'em, than what ya hit 'em with.

If one goes to Loctite's website or gets a hold of one of their catalogs, there are many model numerical model numbers with the same colors. The high strength RED referred to is the 272. They also have one that is higher in strength than the blue, but lesser than the red, and it is green in color. If my memory serves me correctly it is 690. It is about as high strength as you can get without having to use heat to loosen it, or stripping the drive hex/torx head.

I use red #271. If it needs to be removed, you can use a hair dryer or soldering iron (low wattage) to warm it. I even put a tiny amount under the base(s) to seal out moisture and have never had a lot of trouble removing them.
