Default Ring Height for 44mm objective?

Just bought a Vortex Viper HS 4-16x44 and looking at the Medium Talley Rings but was wondering if I could get away with the low rings?

Which rifle and which type of Talley rings?

The 4-16x44mm VV HS has a bell diameter of 2.03” and a 30mm tube, which means it needs 1.02” minimum ring height (bottom to centerline) to set on top of a flattop - plus .125” desired clearance, for a total height above receiver of 1.145”. But... If you have a sporterweight barrel which droops in front of the chamber by 1/8” where the objective taper would touch and two piece bases which sit 1/4” above the receiver, you might get away with less than 1.0” rings (aka lows). If you’re talking about integral bases and a bull barrel, you might need the full 1.145”.

Easy solution, if you have the rifle and optic in hand - cut a deck of playing cards into two sets of 1/2” wide strips. Set the rifle in a vise, make two even stacks of card shims about 1/2” tall, set them on the receiver, and then set the scope on the shim stacks. Add or remove shims from each stack to create your desired clearance out front, measure the stack, add 15mm for the tube diameter, then buy that height of rings.

I have a Remington 700 sps with a remington sporter contour barrel. Rings are the Integral based 30mm rings.

NoMercy is usually spot on. But IMO I seriously doubt if you'll be able to get by with low rings and a 44mm obj. On most rifles they recommend med ht rings for 40 mm objs.
Here is a handy dandy ring height selector: https://www.brownells.com/aspx/learn...aspx?lid=11213

I have “Low” rings on my match rifle - a Heavy Palma barrel and Bushnell DMR II 50mm objective. Nothin’ but a name, the dimension is what makes the difference.

I always go low whenever possible, and I believe you will be able to use the low rings on this rifle/scope. I do use medium rings when the iron sights of a rifle are a consideration.

The Talley integral base rings for the Rem 700 are .43” for the Lows and .53” for the Mediums, from receiver to bottom of scope tube. As noted above, the center of the tube should be 1.145” above the receiver to give 1/8” clearance. The scope tube on your Vortex is 30mm, which is 1.18”, half of which is 0.59”. For our ring height: 1.145” - 0.59” = 0.55”.

Considering the Rem 700 action is 1.35” diameter, and typically have 1.20” or 1.25” barrels, we pick up 0.05-0.075” of clearance. 0.55-0.05” = 0.50”... so Mediums would work. Low’s would FIT, but would only allow approximately 30thou of clearance, not the 1/8” clearance we want.

So looking at the specs, Mediums are your huckleberry.

Hey Davis,
You could maybe if they were Talley as they are taller than other bases that are considered low's. I have a Bergara B-14 with a 6-27x50 scope on it and it's close but after the lens caps still has about 1/8" clearance. Just my .02
