I'm fairly new to the AR and red dot sights. I have a Primary Arms mounted on a full co-witness riser. I haven't really had the environment to play around with target, short, and long range shooting. Fast vs. slow acquisition etc... But playing around in the house the red dot moves all over in relation to the front sight. Isn't the purpose of the red dot to put the dot on an object and shoot? It seems depending on my cheek weld the dot may or may not line up with the front sight. I'm probably not understanding something correctly .... and just need it explained. |

Put up your rear sight and dial in the reticle of the red dot to match your BUIS, with a proper sight picture. Once sighted in, your point of impact should match the point of aim on your red dot. It is only moving, because you are not maintaining the same cheek weld, that won't change the relationship between the reticle and the pint of impact. |

Quoted: Thanks. I actually set up the red dot so it aligned with the rear sight circle (magpull flip ups) and the front sight. It's so weird to me how that little dot moves all over the place (or appears to be moving?) yet the POA/POI is not changing. You are correct in the fact that you do not need to be sighting with the irons, simply superimpose the dot on the target and squeeze. That's the beauty of the RDS. Oh and keep both eyes open, you'll see the dot just fine. In fact you can even keep the front cover on the RDS and use it just as effectively. |
| When properly zeroed, the dot will always be pointing at the rifle's point of impact. The front sight is only pointing at the point of impact when it is aligned with the rear sight. That's why the front sight and the dot are in different places unless you are looking through the rear sight, in which case the dot should be on top of the front sight. |
