ring height question

Is there a guide to ring height somewhere? I'm going to mount a 4.5-14x50 1" leupold to a 20 moa picatinny base. I'll be using TPS rings. Can anyone help with height recommendation? Barrel is hunting weight not heavy. Thanks

.86-.886 would be fine. 1" would be too high in my experience.

Depends on the manufacturer. Look at the measurements not the low/medium/high description.

Semper Fi +1

This might help:

Objective diameter (mm) ________ (not lens dia., this is the outer objective dia.)
+ 4mm (for scope cover) ________

divide total by 2 _______
subtract 1/2 tube diameter ______

The total is the bottom of the scope tube height above your barrel/receiver. (assuming a straight, non-tapered barrel, a tapered barrel will give you some leeway)

This is the height that your base + rings must equal to keep the objective bell off of your barrel, and adds 2mm for your scope cap/cover.

Ideally you would like this height to be as low as possible. Check where the end of your scope bell comes on the barrel, if you have a large taper, you might be able to use a lower ring height.

Check your ring manufacturer specs. Some will indicate ring height at the bottom of tube ring, some will indicate ring height at the mid tube height. If you use a rail, this height will be from the top of the rail. If you use a one piece mount, it will be the height above the receiver.

Hope this helped.

Re: ring height question

For the TPS rings use Low height.

Re: ring height question

Thanks Docb, that's a great formula.

marinetowgunner, thanks a bunch. I see you're an expert on tps rings and egw base's. I went to egw's website and it seems they make a base for my sako m995. Im going to call them to verify. That would be great if it works
