To achieve the proper eye relief, the standard practice is to mount the scope so that the rear of the ocular lens is roughly even with the rear of the charging handle. The position of the scope in the low ring setup appears to be appropriate.

The taller position of the P.E.P.R mount should allow access to the charging handle, even in this rearward position. It will also allow you to mount a folding BUIS at the far rear of the receiver....under the scope. I've rarely read negative comments regarding the P.E.P.R, so I see little reason for it to not work well for you also.

I personally use BCM's GUNFIGHTER charging handles with medium length latches on my ARs, for improved latch access.
