Rifle Scopes Scope ring height

[rockn30809]

I just bought a Bushnell 3200 elite 10x40 for a great price. I'm gonna use this as a temp scope on my Remmy 700. I have a EGW 20moa mount on the rifle. I'm hoping someone can confirm that mid height Burris xtreme tactical rings will work for me. Just wanting to make sure so I can order the rings tomorrow. Thanks

Re: Scope ring height

Read the sticky at the top of the forum and do the measuring first. Only YOU can determin if this set of rings will make the scope match your cranium for proper eye relief and cheek weld. Mids are probably going to be too high.

READ THE STICKY

Re: Scope ring height

I read the sticky, it didn't tell me what I wanted to know. I was hoping someone was using the same scope/ring combo or had seen it used could tell me the ring height so I can order my rings now instead of waiting untill the scope comes in.

Re: Scope ring height

Burris rings are weird in that they measure from the base to the bottom of the scope where most measure to center tube so keep that in mind when ordering. So .750" Burris rings are really .750 + half the tube size which would be .5 so you're at 1.25" when compared to other scope ring heights. That said you should be fine with the 1/4", which is really .750", when using the 40mm objective on a Rem factory barrel.

BUT you might run into problems if you have to move the scope back to far for eye relief and have the objective bell hit the rail with really low rings like the 1/4". 1/2" Burris, might be too tall for your liking though. Personally I use 1" height rings, which is what the Burris 1/2" actually are, and have no problems.

rockn,

The sticky cannot tell you what you wanted to know because it requires you to compute it yourself.

Your Objective is 1.890" in diameter. Take half of that; which is 0.945". That's what you have to overcome to make the objective clear the barrel.

The Bushnell 10x40mm has a 1" tube. Half of that is 0.50". Take that from 0.945".

So between the height of your EGW base and the ring height you need to come up with another 0.445".

Burris 1" XTR rings come in the following heights:

Low 0.25"
Mediums 0.50"
Highs 0.75"

So the Mediums might well be too high, because 0.50" is greater than 0.445" plus whatever the height of your EGW base is. But the mediums will clear your barrel.

So will the lows work? Well the lows are 0.25". If the height of your EGW base at the front of the base, is greater then 0.25", then the lows will work. So if you already have your base just measure the height of it. If you don't have the base yet to measure, call EGW and get the measurement
for the base you intend to order. Most, but not all EDW bases are at least 0.400" high. But they have a bunch of different ones, so it is best to measure it yourself or call them.

Remember to add another 0.15" if you intend to use BC covers. That would make your measurement 0.600" in lieu of 0.445".

As I said before. Its going to require you to do some math yourself. Someone elses setup, no matter how exact to yours it will be, will not necessarily yield the same spec to fit your brain housing group. I would wait for my scope to come in and then measure it to MAKE SURE this is what I would need. patience will get you a long way. I have found that out myself. Hope this helps

As Rob said, if your rings are measured from the top of the rail to the bottom of the ring, just add 1/2 the tube size to get the measurement used in the equation.

Note that the OP is mounting on a Rem700. The height on an AR is completely different from that of a bolt, in that the standard higher cheek weld ultimately dictates the ring height, not the objective. Just about any size objective should clear the barrel, as long as you don't have a really high rail on the fore end. For an AR, 1.5" is usually the standard height, but you can go as low as 1.4".

Right on! And I said for a visual. You can easily see a .5" gap between the rail on my AR which would be the same as mounting on a pic rail on a bolt gun. So the Med height would still be kinda high. I repeat, Just a visual
