Thread: Unpleasant surprises when removing a scope

Just removed a Burris tac 30 from a mount it was in an got abit of a surprise
A lot less than ideal


The culprit, I blame the mount but it was me who tightened it

Ouch. Maybe a lapping bar for the next mount

I think it is a combination of over tightening and soft scope tube,
I think the cantilever mounts were tightened so much that the edges were pulled down and into the scope

maybe its time for a torque wrench......

I have a torque (screwdriver) especially for that type of work. Got it off Sinclairs. Uses hex head fittings, simple bit of kit. Was around $150 US

Unless you are using a big heavy recoiling rifle 14"lbs, per screw is all you need.

funnily its never happened with a leupold.....

I do mine up till Im scared of snapping them off and never marked a tube.

Why do I get the impression you would only need a large hammer and communicate in single syllables, to be happy?

If you can't fix it with a hammer you have an electrical problem

'If you cant fix it with a hammer'....then your hammer wasn't big enough in the first place!!!!!!!

honestly if the scope gets squished it wasnt strong enough.

this is why optilock rings rule, tigheten them up and no problems at all, rudimentary cantilever mount absolutly roots the scope tube

My Premier got squished and they have mil contracts. I'd say operator error more likely. You can generate a fair bit of force once things start to get leverage.

Thats coz the rock ape that had the scope before you, used a extention bar to tighten the ring screws

absolutly my fault with wrenching it down.

still think it should be stronger tho, I hate thinking my scopes might move

With a few exceptions scope tubes are alloy and if you tighten them up enough they will crush. Some mounts will let you get away with a bit of overtightning others will bite you in the arse. I use a W&B torque wrench and use 15 ish inch pounds max but got lazy a whie ago and crushed a vortex diamondback. Verticle split rings are the worst but still my fault. Best thing was I owned up and vortex just repalced the scope totally free, not even charging for freight.
