Need help with zero for ar10

[9mmrevolver]

Here is the deal. Cmmg rifle, true glow 8-32x44 scope mounted to 1 inch from rail to bottom of scope. Shooting 150gr fmj.

Took it out shooting today and could not get the elevation down. At 100 yards I'm about 4' low with the knob dialed all the way up. My buddy said to dial it the other way . So I did and made the drop even worse. Do I need higher rings or what am I doing wrong

[9mmrevolver]

Help meh pleeeeeaaase

[ElvenSoul]

Hit so low it wouldn't even come close to get it on paper

get rid of riser and get right size scope rings.

[9mmrevolver]

I bought extra weaver rings and my obj still hit the rail. Which is why I went with a riser and low rings

[hermosabeach]

Some risers are built in with 10-40 degrees of elevation.

Some no name items are just junk.

If your riser has elevation, do you have it mounted backwards?

Unless you need the riser, dump it.

I have also seen rings that have built in elevation. Again do you have these and are they mounted backwards?

It is alway possible for things to be out of spec.

So who makes your riser?
Who makes the rings?

[9mmrevolver]

I have around a 1/4 inch of room between the obj and the rail.

[9mmrevolver]

I will check. Didn't know that

[JagerDog]

I'm guessing you have a 20MOA riser/rail mounted backwards.

Of course mounted correctly you may find you can't get POI down.

How much internal adjustment in scope?

[9mmrevolver]

Measurement of riser

[9mmrevolver]

It's in 1/8 adjustments

That's 32 clicks for 4 inches at 100 yards, fun. Your scope is probably jacked up. You shouldn't run out of adjustment at 100 yards especially if you're not using a 20-25 moa rail.

I see your point. I was thinking when I got the scope I was going to do hopefully out to 1k so the 1/8 adj would help me out at that distance
