Hey guys, new to the site and to AR's in general.

Just had this 300 Blackout built and I was messing around with a few sights and have a question.

Iron sights work just fine, so they are always an option.

I tried a Reflex site and found that it was too low and I had to lay my head at an odd angle to even see the thing (dont have to with iron sights).

Decided to try this See All sight and I like it but have the same issue with having to have my head down at an odd angle to pick up the delta sight picture.

What am I missing here?

If I don't slide either the See All or my Reflex sight onto the rail but sit it on top it is better, but both could still use a bit more height.

I am sure it is something stupid, but I can't figure it out. Seems like either the See All or Reflex would need to be on a mount of some sort above the rail to come comfortably into line with my eye.

Like I said, I can pick up iron sight (typical AR sights) fine. They are at the right height to be in line with my eye.

Here is a picture of it on the rail.

You need a riser. The AR15 has an inline stock, unlike a lot of other rifles that have a stock that drops a bit below the axis of the bore. This is why you see most AR optics up on higher risers.

You just need a riser, the ar stock comb  is higher than most. I'm not familiar with that sight, but search see all riser, or someone will be along to suggest something . ETA:Beat by 8 seconds :)

Got it, thanks a ton.

This site does not work well on a mobile device. Have to go to my PC to do anything.

If I lived nearby I'd bring a couple risers just to try that sight..........

Let us know how it works out at what range distances.

Look for 1/3 co witness when shopping for your rds.
