Maven RS1.2 2.5-15x44 new model

That is a 1.20" shank blank vs a 1.135" tikka prefit, so maybe you are seeing the 0.0325" difference?

Your barrel is a Tikka prefit. His barrel isn't. If you zoom into the photo, I can see just a touch of shank diameter thats bigger than the Tikka nose, so he's using a proof blank that wasn't original setup for Tikka tennon OD. Its either 1.200 or it was turned down a touch. I could be totally wrong, but thats what I'm seeing in the pictures.

Gotcha! Thank you guys for the clarification

Thanks all, looks like I'm going with the medium.

Thanks all, looks like I'm going with the medium.

Sportsmatch TO84 "Medium" are still pretty low, I think the HT073 High are closer to UM Medium.

Very solid scope,

That looks like an awesome scope

To combat the really freely spinning turret I put a 0.053" Oring under the elevation turret.
Factory looks ~ 0.037" (probably 1mm)

Turret is now a tight fit and won't turn as freely/easily. Closer to an SWFA or Tenmile turret.
If you can score a 0.050" turret I suspect that would be just right. But this is good enough for the girls I go out with

Is this like my loss of innocence where if I stare at it long enough I'll figure out where to stick it?

I'll figure out where to stick it?

You put it where the thinner factory o-ring that you took out was.

This one might work.

Ha, yes what @BBob said. Remove factory Oring and use that spot

1.5mm / 0.060" is too big

The 3-9HD uses that size. So I robbed one to try it on the Maven. You cannot get the Maven turret on.

0.053" is as thick as I would go. Takes a little coaxing to get the turret on the first time

Is that the o ring or do you have another source/number you would share?

I stole the oring off of a chinese rimfire scope, so I don't have a specific sku to share. This is what i would buy:

ID = 0.75" to 0.85" (it needs to stretch)

Cross section diameter = 0.045 to 0.053" depending on how tight you want it.

Personally I think 0.050" would be about right if it exists

An alternative is a spot of electrical tape inside the turret to tighten it up.

My other scope has had this tape inside for about a year now. I've removed the turret a dozen or so times and the tape hasn't moved or peeled off.

Let me know when you figure out the right one.

This is what ended up doing on all of mine was well before Fall.

I used to have occurrences of the scope “dialing itself” fairly often, I haven’t had this happen once since doing so.

One of these two.

A side rant, because I'm sick of AI slop. I type in 0.75x0.053 o-ring. Googles AI says this matches a standard O38 o-ring size. An O38 is 1/16th, or 0.0625. So, wrong and worthless. Every time someone says xxx AI program says...... I just want to cram a dirty sock down their throat and wrap their face in duck tape leaving only the nose sticking out and tell them to have fun taking it off.
