I'm well aware that 5-25 power is overkill for the ar15,,,but my eyes suck and I would love to spot my own rounds. My question now is if this is even doable.

Can I mount the optics high enough for that 56mm objective to clear the rail and still maintain a reasonable cheek weld? If so.. who makes that mount?
 
In theory, that should not be a problem.
If I am not mistaken, the standard iron sight height above an M4 rail is 1.5", that is 38.1 mm (to be double-checked, this is out of memory, and I don't own no AR15oids to measure).
The sight height (scope axis) of a 56 mm objective, if you count the flip cover and a couple mm margin, is > 32 mm; in other words, the objective should fit no problem.
There are plenty of 1.5" rings / mounts for 34 mm scopes.
Spuhr SP-4002 should do it just fine, if you have the budget. 34 mm Nightforce Ultralites are also available in any height you may need.

Steiner 5-25x56 on a 34mm Bobro mount. No problems clearing anything. Its big on the gun but works perfectly! Sight picture is perfect with the stock thats on it. If not put a PRS stock on it and go have fun!

An American Defense Recon 0-MOA mount should work just fine. I run a 20-MOA cant and have no issues with a 34mm tube and 50mm Objective; still have a 1.2cm clearance.
 
That's a 20moa base on the picture above. It's my cheap truck AR that gets tons of rounds down it either with a 1-4, aimpoint, hensoldt red dot or some other 5-25x56 optic like the Steiner in the picture.

Hi, new guy here. I've got a Bushy coming in with the 34mm tube and 50mm objective. I also ordered the ADM Recon SL 0-MOA but it's going to sit on a 20MOA rail. The ADM says it's 1.19in from centre to top of the rail, so if my math is right, that's 30.226mm and half of a 50mm objective is 25mm, which leaves 5.226mm opf wiggle room.

That being said, the tip of the objective will be lower because of the 20moa rail it's sitting on, and if I throw the sunshade on with flip caps, it will eat up more of that clearnace. I'm cutting it really close, so I'm hoping it all fits when everything arrives. Does anyone have any pics of a similar set up?
