Mounting Liquid Inside Rings

[Full Curl]

My previous gunsmith was old school but did awesome work. He has since retired. I had him mount a few scopes over the last 10+ years and I never had any issues. I always gave him quality rings but he would put some type of blackish liquid inside the rings and then mount the scope. Whatever it was he kept it in a small squeeze bottle with a needle tip. He would apply it very thin and then mount the scope while it was still wet. If I ever later removed the scope it came out fine and there was a paper thin layer of the stuff that was sort of grippy or semi-rubberized on the inside of the rings. A little denatured alcohol or acetone would quickly remove it and there was never any on the scope tube.

Anyway, does anybody know what the stuff was? Maybe liquid electrical tape? Scotchkote?

Does anybody use it anymore? I first hand witnessed the following benefits (1) better scope alignment, almost like bedding the scope, (2) positive grip for extra insurance on the side of the mountain, and (3) protects the scope from marring.

I know with today's CNC rings they shouldn't "need" this but what would it hurt for the extra insurance it could provide??

Maybe some type weather-strip adhesive or something? I use Ring- True tape from High Power Optics, grips great and protects your scope.

I've used rubber cement on the rings. I read about it on accurateshooter.com.

kinda fills any gaps and supposed to help guard against ring marks. What you're describing sounds like what it was like when I removed the rings later. Very thin, rubbery gasket. Easy to remove. Nothing left behind at all. And, no ring marks.

one of the loc-tight products?

Yeah, I'm not sure. Wish I had asked him what it was before he retired. Seems like a pretty good idea for just some extra insurance. I googled Scotchkote and there's some info out there on it... probably very similar to rubber cement??

I know a man that uses liquid electrical tape in the same way

I use liquid electrical for several things - may need to add this one. Thanks!

I think Scotchkote is pretty much the same thing as liquid electrical tape, or at least similar to it...??

 

[trigger puller]

I use Arc rings so I am not worried about movement and or marks, but it sounds like liquid tape

RTV?!

Could it have been Permatex Ultra Black? It's a gasket making material in a tube.

Just my guess.

I would think he would tell you what he used if he's still around. David

I use liquid electrical tape. Started years ago and even using some of the best rings available I still use it. When you take them apart it just rubs off. Just my little bit of comfort.

Unfortunately he moved away and I can't get a hold of him. Lots of good suggestions here. Funny how something so cheap and easy isn't used by more people. Seems like cheap extra insurance to me.
