Gents,
I recently took a PSA build to the range to sight in the backup irons and the micro dot. ive never really played with red dots before so its a relatively new thing for me. the magpul back up was dead on at 50. I co witnessed the dot and then lowered the rear sight to shoot with the dot. the dot as all over the paper. I found that while looking at the dot through the irons it would go where I wanted it to. when the irons are down its a nightmare. Can anyone glean some knowledge on me as to what I might of been doing wrong? I should also note that I wear glasses and have a stigmatism. |

Quoted:
Unlike irons or a scope reticle, you should focus on the target when using a red dot. It sounds like you are probably focusing back and forth, and that is affecting your ability or lack of repeatability. Try this, if you still have problems, contact PA, they are very good folks.... |
| does it group only when the irons are up? have you tried a group with irons and then a group with just the red dot and then back again? if it only groups when using the irons and red dot youre probably focusing on the dot rather than the target when not using the irons. |

Perhaps you have some misconceptions on using the dot. Setting the dot on the front sight post then folding down the rear sight is a good way to get on the paper with a new dot sight assuming the irons are zeroed at that same range. I use 50 yds for both. You will still have to make adjustments on the dot sight. Now your wording leads me to think that you believe there's a problem when you are not using the rear sight because the dot appears anywhere in the lens. This is normal - the beauty of a dot sight is it doesn't have to line up with anything - after sighting it in, you just put the dot on the target and shoot. Imagine its a laser beam that you have sighted in - you put it on the target and shoot. With the reflex dot sight, You do not have to center it. That's what makes it faster than irons.
Congratulations, you have co-witness. Now forget it, because it has no practical application. You never use the irons and dot at the same time, and the dot does not have to sit on the front sight post when you're not using the sights. Co-witness actually proves what I'm saying - the dot magically sits on the front sight post when you turn it on while looking through the sights, assuming both systems are zeroed at the same range with the same ammunition. What you're not getting is that without using the sights, the dot can appear anywhere in the field of view depending entirely on how you are looking at it, but IT STILL IS ZEROED. You just learn to 'move' the dot to a convenient place in the lens that gives you the field of view you need, put the dot on the target as well as you can and squeeze one off. Shoot three rounds as carefully as you can and hopefully you get a fairly small group. Now use the adjustments on the dot sight to move that group to the point of aim. When you get through, flip up the rear sight and the red dot will sit on the front sight. Fold the rear sight and the red dot can be anywhere, but again, IT IS STILL ZEROED! |
