Either one will work fine. If you read the fine print, the purple is for smaller screws than the blue, but most gunsmiths and "old timers" have been using blue forever and it never seems to fail. I've used blue for many, many years and I've never had a scope or red dot get loose from using it instead of purple. If you don't have any on hand, and have any concerns at all, get the purple. I'm not sure there's really any noticeable difference. I do know not to use red unless you want to apply heat to remove the part. I've seen guys use that and they usually learn the difference real quick.
I bought a Vortex scope. I called the manufacture to ask about loctite and they said not to use it. Just torque the rings to what they said and I haven’t had an issue.

I use blue lock tite with food results on the base screws. In a pinch nail polish or enamel paint will work well also. I coar the screws and under the heads with it. ANother tip is to make sure the threads screws and bases are clean and free of oil and preservatives. before mounting.
I agree about using Locktite on the base screws and not the rings. I also degrease the threads. I have used red a time or two in a pinch. To get it loose I just held the tip of a soldering gun to the screw head for a few minutes.
I just use super glue. It hasnt failed on me.

generally none, but if i felt inclined it would be the blue.
Been using the blue locktite for 35 years and haven't had a loose screw yet. Clean the threads on the screws and receiver with acetone or lacquer thinner first to assure a good bond.

My avatar is almost a dead ringer for my little buddy Chico. Six pounds of mean that thought he was a Pit Bull. Miss that little guy.
Clear fingernail polish has held the scope rings and bases on my 300 wby mag since 2000. But I use blue if I have it.

Why use it at all unless it's a super hard kicking mule
Of a rifle . Neither myself or my dad has ever used any thread locker on rings or bases never had a problem .
If you find yourself in a fair fight, your tactics suck!
My son-in-law learned about blue loctite with his Marlin 1894 in 44 magnum. He had installed his scope base without any sealant and used his traditional very hard torque on the base screws. About 2 years and too many rounds later he couldn't hit anything with the rifle. He asked me to look at it and the only thing I found wrong was the base was loose on the receiver. I remounted the base screws with blue loctite and allowed it to cure, then returned the rifle to him. That was several years ago and the rifle still delivers the tight groups it re-discovered after my fix.
I've used blue with good results.

222. It is commonly used by gunsmiths to prevent tiny screws on telescopic sights from loosening due to vibration. I've written an article about Loctite 222 vs. 243: https://www.stickyaides.com/loctite-222-vs-243/
Hope it helps!
I like to use blue on bases and purple on rings. I don't go crazy with it, though. Just a whisper.
I generally also stop at 15in-lbs for rings screws, especially if they have a hint of locker on them.
blue243 works for me
Blue! Another very important aspect of scope mounting is using the correct torque.
I use blue because I have it. I think either would be fine.
blue here when I use it. sometimes we forget until there is a problem
I started out with nothing and I still have most of it left.
