So, is this a dumb idea, an interesting idea, or might it actually work?
Every scope I mount on everything I have
gets degreased with an acetone rag and
the mounting surface of the base gets
loctite, and the screws get loctite.
The ring mounting surface touching the
base gets loctite. The bottom inside of
the rings get loctite, the scope laid in
place and the top half of the ring gets
loctite and set down on the scope and
snugged with the screws that are coated
with loctite. It doesn't even come close to
hardening in the time it takes to align the
reticle properly and adjust the eye relief.
After everything is copacetic, it gets
tightened to where it needs to be and is
set aside for a day or three.
If I had any true practical reliable way to tell for sure that I would never ever have to remove a scope for any reason, I'd use JB Weld or something similar or stronger if I could find it
I'm also a big fan of Signature Zee rings for circumstances where you need a significant offset between the ring centers.
So, there is that - the glue may be more of a problem than the tape. YMMV.
I'm thinking about attaching the tape to the rings rather than the scope so that the non-adhesive side of the tape is touching the scope. I see your point about the possibility of the finish being different where the tape touches the scope body. This scope is graphite gray rather than black, so the difference MAY be less.
1) Proper rings grip the scope effectively, so adding something between the rings and scope won’t particularly increase grip.
2) Improperly done, overlapping tails can create high points which can buckle or distort the tube.
3) Improperly done inside well fit rings, any tape adds dimension where none was meant to fit, again adding pressure points, distorting the scope tube.
4) The idea that the tape will flow only to the low points and will be compressed out of the high points, stress relieving the contacts is delusional - the high pressure points will remain pressure points, and the low points will remain low compression points.
5) Given the incorrect material, the adhesive and tape itself could become effectively mechanical lubrication between the scope and rings - insert banana peel meme
6) Adhesives and plasticizers in the tape may degrade over time, either dimensionally changing or chemically interacting with the scope or ring finish
So for me, tape in the rings is a 4 letter word. No benefit, and potential downside... no go.
Is why I have never tried it, gotta be better materials for shimming. Rather buy better rings.
I've got to confess that I've done this once before on a 3-gun rifle (5.56 AR) that recoils like a .22 and not had any issues. The tape has been inside of the rings since late 2016. There's been no indication of a problem but of course there's also been VERY little recoil although high usage. I haven't removed the scope to see if there is any degradation and the mount is a 1-piece mount rather than a pair of rings. I'm inclined to give it a try on this precision rig. I don't see any downside since everything will be torqued down properly and I seriously doubt damage will occur as a result of lining the rings with electrical tape. I definitely won't be overlapping the ends of the tape.
@Varminterror and @Walkalong I appreciate your thoughtful analysis and thank you for your opinions even though I'm going contrary to them.
but electrical tape on a precision rifle? no way
(Not an original idea, I read it on the internet back in the 1960's!)
I also lightly lap every pair of rings that I mount. I know that opinions about lapping rings are about like opinions on die brands or bore cleaners but I do it.
I also use a torque wrench and tighten all of the screws to their recommended torque.
My tap, lapping bar and compound and lug cleaning tools all came from Brownells. Taps by nature are fragile and this small tap would be really easy to break so if you choose to do this be very careful. I use a cheap keyless chuck for a cordless drill to help me hold the tap.
No need to risk damaging the threads like that. A pipe’s cleaner or Q’s tip will do the job well.
