Zeroing my scope... end of the road!

[Saluki91]

I would appreciate any assistance the collective can offer with this situation.

I recently purchased this scope for my AR-15:
https://leapers.com/index.php?act=prod_detail&midx=2266&allids=2266&itemno=SCP3-U312AOIEW

After mounting it with the supplied rings, I attempted to zero the scope today. Key word - "attempted"

I won't bore you with my prolonged ride on the struggle bus... suffice to say the scope was shooting very low. After moving the elevation turret to its highest setting, I was still holding 5.5" above my target at 50 yards. I didn't have a problem with the size of the groups, but a 5.5" hold at 50 yards is just screwy.

Is it possible to shim the rings to compensate? I'm pretty happy with how the scope fits in relationship to my eyes. Perhaps a different set of rings? Different mount? New scope? New hobby?

Thanks in advance for your input!

Did you have an optic mounted on the rifle before? Is it mounted to an integral rail? I might try switching the rings position frontvto back and see if it shoots high. Might need a new set of rings.

No - this is the first time I have mounted an optic on this rifle. The scope is mounted on the receiver's rail.
I'll try switching the rings... I wouldn't have thought of that. THANKS!

While your doing this use a level on your rail. There was a thread Iirc 2 yrs ago about a savage 110 flat back that wasn't level. The fix was to grind some material to level it out. Not a fix I'd do myself, I'd prefer that to a Smith.

I have used electrical tape inside the rings.but that can put pressure points on the optic. Another thought is mounting one ring saddle to see if it sits into both rings

I'll work on those suggestions this weekend.

Cheers!

Just remember to get your scope back to mechanical zero before you re-mount it. I used to place the objective against a mirror and move the turrets until the images of the reticle are congruent. In other words, until you can only see one image of the reticle instead of two.
You can also count clicks, but it’s more tedious.
Good luck!

Thanks... a good reminder for sure!

Hoes it going with your scope?

I've seen scopes that had the dials reversed. Instead of moving the elevation up as directed on the turret, you may have it maxed out down. Try turning the elevation knob in the other direction just to see how it changes bullet impact.

I found "a few" things that needed addressed:
1 - The mount for my offset red dot was making contact with the scope's objective bell. I was sure these two components were free and clear of each other... I was wrong.
2 - I moved the scope to the most forward position on my receiver, and the red dot as far back as possible.
3 - This must have fixed my issue, as I was able to zero the scope at 50 yards with three shots.

Looking forward to loading some 77gr Noslers, and seeing how that 50 yard zero translates to 100 and 200 yards!

Glad you got it figured out, thanks for the update.
