Rifle Scopes Tikka Tac Ring Height

[Magstang1]

Sorry. I know. Another damn ring height thread. Not much info on the Tikka's around.

20" Tikka Tac with the factory picatinny rail on the reciever. Probably a Vortex Pst going on. 30mm tube and 50mm obj.

What height rings?

For the most part .885" center height rings will work in some aspects you can go as low as 0.823" center height.

Anyone care to check my math before I spend some cash?

Right now my rifle has a cheap (don't laugh, I bought it this way) Tasco mounted up. My current measurements are:

Clearance from objective bell to barrel: .1"
Top of picatiinny rail to bottom of scope tube: .21"
Objective outside diameter: 1.84"
Scope tube diameter: 1"

My Nightforce measures:

Objective O.D.: 2.31"
Tube diameter: 1.18"

The current center height of my tasco as it sits in the rings is .71" over the rail. (.21" plus half the tube O.D.)
To accommodate the larger objective I need to move up .235" (2.31"-1.84"=.47" divided by 2 = .235")
.71" + .235" = .945"

It looks to me like I need 1" high rings.

Sorry for the long version. I've never bought rings for a bolt gun before.

Any suggestions?

I ended up with 1.0" Nightforce Ultralight rings and a Nightforce NXS 3.5-15x50. There is just enough room for the cover to slide on.

Hope this helps someone eventually.
