In your experience, what is the best thread locker that you have ever used for scope bases and scope rings. Please include info on scope removal; whether heat is needed.

Loctite Red 271 - It takes a lot of heat to remove, 500+ F. Often, I use a wood burning pencil or soldering iron to apply very local heat.
Once, I used Epoxy on a very heavy recoiling dangerous game rifle. Those mounts and scope stayed on for many years until sold.
I have used fingernail polish on some screws, and a soaking in acetone helped in removal. However, some screws could be removed similar to Loctite Blue 242

The blue stuff. 242 or equivalent. No heat required

Blue Loctite is all a man needs. I have used JB weld on a one-piece base when either it or the action was off just a bit. I'm leaning toward it was the action because Ken Farrell made the base. I only used the epoxy to bed the base, kept it out of the threads, but it probably wouldn't have mattered as that base was probably never coming off lol.

I have no one favorite, each type of assembly has it's own unique needs. I likely use 242 or 220 (roughly wicking grade 242) the most.
To me, 242 on a ring screw should be considered like you've chosen to use 271 (red) on them. I don't, those screws go in clean and dry and are torqued to spec. Never had a scope ring screw come loose. I'll suggest that if scope ring screws are coming loose that there is a more fundamental problem that needs to be addressed.
242 or 220 for base screws and mating AR barrels to upper receivers.
I have used 271 on firearms, but I can't recall when or where or why.

The blue and red loctite on different applications. The blue for bases and rings. They will untwist
Thanks

Glad you posted this Sentient!
I used Blue 242 Loctite for years. But on screws I wanted to stay put I mixed Blue loctite with Red Loctite.
But these last few years I have been using Vibratite. It has been holding firm and for folks who love to change their mind it has the advantage of being reusable; that is, you can unscrew it and then screw it all back together and it still holds firm.

Vibratite for me. Even on my light 7PRC everything has stayed connected without any issues.

This. Sally Hansen. Also great for tying flies.
The same as JKB57 and FireFlyFishing clear fingernail polish for over 40 years it just works.
Blue loctite or orange Honda Bond. It's Honda's medium strength threadlocker. I've used vibratite also but I'm still on the fence with it.
