OK, then let me ask this. The original mount was just the standard rings I bought with the scope. They kept the scope lower (relative to the bore), but the eyepiece was also obstructing the charging handle. I was told by a firearms expert that I should not ever obstruct the charging handle. So I bought the Burris P.E.P.R. mount, which did raise it slightly and move it forward, keeping the charging handle clear.

Should I go back to the regular rings, even though it might obstruct the charging handle a little?

Thx.

I've never used a scope on an M16, just iron sights. I picked a medium mount that lets me cowitness my iron sights through the red dot. If it isn't TOUCHING the charging handle and you can operate it, I can't see why mounting it lower will hurt. You were shooting indoors at 25 yards? All the charging handle does is move the bolt carrier back and forth...once the BCG is locked in battery, the charging handle has no more effect on it

OK, I'll certainly try mounting the scope with the old ring set and see if that makes a difference in the sighting. I could manipulate it enough (in the prior configuration) to charge the rifle. We'll see.

Thx.

Yes, yes! I gotta steal this. I have to constantly correct people about this.
It's called the jump angle.

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.

What is your primary ammo used with the rifle? We may be able to help you choose a zero distance well suited to the bullet weight/velocity of your ammo.

OK, First is the image of the original mount that obstructed the charging handle.



Second is the image with the Burris P.E.P.R. mount.
