Scope ring height

[snowplow]

Hey guys, just curious if any of you have put a Arken ep5 on an AR10. Specifically, a Rock River LAR-10 if it makes a difference.

I'm just curious if you guys think a set of low rings would work or do I need something else?

Ultra high rings or AR height mount. 56mm objective and probably want room to add caps.

Probably go with something 1.5”.

Nothing under 1.5” height for an AR especially with a 56mm objective.

 

[TonyAngel]

Same here. 1.5 for the EP5. Mind you, that scope is a heavy beast.

You can probably get away with lower rings if your hand guard doesn’t have a top rail. But, in 2025, “get as low as possible” is obsolete advise.

Is there any advantage to rings versus a one-piece mount?

 

[Sum Ting Wong]

Nope. Usually easier to get the scope forward enough with a cantilever mount on an AR. Best to keep the rings/mount completely on the upper and not the handguard.

I went back and forth over this not too long ago. I had a weight budget I was trying to stick to. The one piece nightforce I was looking at weighed 6 oz. The rings I was considering were from American Rifle Company. The rings alone were 6 oz, but very robust. Theoretically, the ARC rings should be stronger because how robust they are, but the Nightforce one piece ensured that everything was lined up properly.

I was thinking that on an aluminum receiver with an aluminum rail and things not always being in spec, the Nightforce was the better way to go.

On an AR, no. Get a good mount and be done with it. A cantilever mount actually makes mounting and setting eye relief better.

And the height is not just about clearance for the objective but comfort for you behind the scope. ARs are different than bolt guns in how you set on the stock for check weld. I had a cheap mount that was like 1.3” height and I had to almost push my face down to get a good sight picture. 1.5” is so much better.
