scope mount problems

[joe blow]

HI guys,

I have a 4-16x50 scope I was going to mount on an ar15 I just put together. Long story short, the mounts that came on the scope are too short and the front of the scope contacts the rail. Once I put the flip up caps it wont even mount. I know they make riser mounts for it but not to sure if I should go one piece or buy two individual mounts. I have read the individual mounts can become problematic over time and I should stick to a one piece. With the size of the scope, how tall of a riser should I look for?


I am new to scopes and want to buy the right one. It is not an expensive scope and originally was going on my Mosin but the eye relief was not enough....figured I'd put it on this rifle.

Any affordable suggestions are welcomed and appreciated

Thanks
Joe

Calculating the distance to the saddle

Here is a graphic I made on how to calculate the minimum riser distance. You need to add a little extra to assure the objective bell does not touch the rail.


E = riser or "saddle" distance of your rings.
Dt = tube size
Dobj = objective bell size

As to one piece or two ring mounts? From what I can tell ... it really appears to be a matter of personal preference.

For the AR-type platform I really like the one-piece mount with quick detach levers. And yes ... the Burris QD PEPR mount really does return to zero.

As for the permanent or semi-permanent installation; I prefer the Millet angl-loc windage adjustable steel ring series. These things can take the heaviest recoil and are windage adjustable. The windage adjustable allows me to keep the internal optics as close as possible to the original centered factory setting.

Thanks for that. Just a question since I really don't know....is it really crucial to get the correct spacing or as long as the scope does not contact the rail and it clears without sitting too tall, the mount is good? I just figured but a riser that is 1/4" + over what I have and it's fine....is this the wrong way to do it?

Thanks for the help

Just get a PEPR. They're a good budget setup with the proper height for AR.

As long as the scope does not contact the rail you are fine.

Ok that was my hangup.....didn't know if too tall is bad.

Even for the large scope I am using?

You need to mount the scope such that the objective bell just clears the rail. If you mount the thing too high, you will not be able to get a proper cheek weld on your rifle.

I'd get a one piece picatinny mount that adopts to a picatinny rail. They make these in different sizes, but you can also get one that builds in a cant, which is generally suitable in any event.

I was just coming back to ask that same question since I came across risers that give me a 1/2" of rise which would be perfect IMO. still thinking about the burris PEPR as well

Thank you very much to all for the help!!

After doing some searching and asking it looks like this will be a good choice....so far

Thanks

Bought the PEPR from burris. It solved my issue and still gave me atleast 1/4" gap between the rail and protective caps. It raised the scope to a more comfortable eye level....just feels RIGHT now

Don't forget to send in the $20 rebate form, you can get it from Burris's web site if you don't have it.
