Did I miss something? If the gun is shooting low and POI does not change when you adjust the elevation, I would say the scope is not working. It should move the POI somewhere.

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.
Thanks! I'll change the mount to make it align with the handle.

Yes, I'll definitely recess the mount, per "man's" suggestion. (Sorry... can't figure out how to stop the icons.....)

How hard is it to replace the charging handle with a BCM? I've not yet delved into any mods to the upper or lower itself.

Is there a favorite way you use to test/calibrate the scope "standalone" (i.e. not mounted on the gun)? I can see the reticle move relative to the target's bullseye when I make adjustments, but no matter what I do, the placements are still just south of the bullseye.

I'll start over again and get the scope reset to factory specs. Then I'll change the mount to ensure the eyepiece is flush to the charging handle.

Thanks all!

Google search "scope box test" and you can probably do the test with the scope in a vice or something similar.

Edit.... This explains the box test well.

Here is my last DMR poodle shooter with a P.E.R.P mount and SWFA SS 10X scope. MOA all day long with match ammo.

Try this. ..fire a 3 shot group. If low, aim at the exact same point you aimed when firing, then, holding your rifle steady, adjust the crosshairs down to meet the center of the group. That should zero it at that range. If the next group is low, the scope is suspect imho

Well, first I'll do the "scope box test" per caleb's suggestion. If it comes down to being a "bad scope," then I'll probably just replace it with a BUIS and use that instead. I think Pig may be right... Why put a scope on an AR /M4 variant if you don't need to shoot it at those distances? Better served on more of a "long distance" type rifle.
