Blue Loctite on scope base

I had a base come loose for the first time. Thoughts on blue loctite.

I’ve heard blue is the way to go. Do NOT use red. I just took one apart that appeared to have clear fingernail polish on it. It dang sure wasn’t going anywhere on accident.

I use it on bases and rings. Not red.

I use red on bases (because I will never change them) and blue on rings (because I might change the scope).

My understanding is you want to use Loctite green which is for smaller screws and IS NOT permanent.

I've found it at Advance Auto. However, I think all the Loctite products come in a blue tube so you have to read the package to make sure you get the right one.

The funny thing is I've never used Loctite on any of my rifles but only keep a tube for friends who feel they need it.

Blue threadlocker on my scope rings and bases. Semi permanent but can be removed. I have taken scopes on and off many times.

Well, it's really purple. Bottom line make sure it says "low strength".

I use it on bases as well as ring cap screws. I also tend to go tighter by about 5 in/lbs than manufacturer's recommendation.

There have been guys TIG weld them down. That's commitment right there!

I use it or nail polish on just about every mount I do. Never had anything come loose yet.

Purple is a lower strength than blue. Should work fine for bases and rings.
You should not increase torque. You should actually decrease torque. Torque specs are set based on a dry contact. Liquid Loctite creates a lower friction lubricated surface causing the screws to be over torqued even at spec. Over torquing deforms the screws too much. Someone did a big long explanation of it online if you want to look it up and calculate the corrected torque needed at a given ambient temp. Just stick with the manufacturer's specs or 1 or 2 in/lbs lower and you'll be fine.

I understand all that.

And I've seen things come loose following torque spec. I'll keep doing what I'm doing.

Thanks. It’s the first time having a scope come loose

IMHO, the caliber you shoot has much to do with screws working loose on a rifle.

Well, almost. The amount of recoil more specifically.

My 7 Rem Mag, with a full case of H-Retumbo and a 180 gr is a joy to shoot. Weight of rifle, and a good muzzle brake makes that possible. By contrast, I've shot some .30-06 this year, with a bunch of H-4350 and a 178 gr that were absolutely no fun to shoot.

Pretty much all a guy needs to know.....
