Reflex sight placement on AR pistol

[Dunraven]

I just got a rock river ar pistol. It has a top-picatinny rail that runs the entire length of the upper, at least 12 inches. I have a reflex sight for it, but am not sure where to place it on that rail. Does it belong in any certain place that works better, or is it personal preference? Thx.

Approximately centered on the ejection port for me.

It needs to stay on the receiver for sure. I mount mine more to the front of the receiver.

So mounted in this area looks good then?

I prefer mine more to the rear (just in front of the rear sight), try it in different positions and see how you like it.

AR’s are meant to run with optics mounted on the very front of the receiver itself. It shouldn’t be mounted on or touching the rail at all due to possible shifting.

A reflex sight is meant to be fired with both eyes open, and the forward receiver mounting position is ideal for that.

Correct. They're also (as are holographic sights) meant to be shot with target focus, not reticle focus.

 

[Cclary60]

Also correct. I run my competition red dots as far forward on the receiver as possible and never look at the actual reticle. The dot naturally goes where I want it to.
