| I have a RRA entry tactical with a regular carry handle instead of the tactical one. Anyways the rifle is zeroed but the windage is adjusted so that the rear sight is moved quite a ways to the side. It's been awhile since I've shot it so I don't remember what side, but if the aperature is lined up in the middle my groups (and anyone else who shoots the rifles) are several inches beside the point of aim. Also, I can shoot groups ranging from1.5-3" at 100yards depending on how I'm doing that day if I use the small aperature (I know it's really for further distances), but if I switch it to the larger aperature my shots seem to go all over the paper. I suspect this is just from my lack of range time with the rifle, but it sure is frustrating. |
| the larger ap is going to give you wider groupings, and I think that from what your describing, you don't do a good check weild to the rifle, and it sounds like you got it to work for you anyway, and when omeone shoots it correctly, the diff is noticed, I've seen this before |
+1 on the cheek weld as an issue. I'm curious what a "correct cheek weld" is.  I see people that have strange positioning but as long as you consistant and comfortable you're good to go, as long as your face is touching the upper part of stock. When other people shoot your gun they may be off on point of aim point of impact but if they know what they are doing they should still have a good tight group. Just my .02

You probably have a canted front sight. Look at the front sight real carefully from the muzzle end, unloaded and your finger off the trigger of course and see if the front sight looks perfectly straight. I had an upper with a canted front sight, I sent it back to get fixed. Canted sights seem to be common recently. |

You need to consentrate on the FRONT sight, what it sounds like you are doing is losing focus on it when you change to the larger apeture. The larger apeture is allowing you a larger field of view, and distracting you from a good sight picture. The rear apeture is only intended as a reference for your alignment, and should not even be noticed, (hence "ghost sight"). The mantra of the firearms instructor: Front sight! Front sight! |
| I'm not really that concerned about shooting crappy with the large aperature as I was probably fatigued from shooting 50rds through my yugo mauser prior to this on the particular day I was talking about. I zeroed in the M4 that day then switched to the mauser for awhile then I went back to the m4 and switched to the larger aperature since it had been properly zeroed. The rear sight does bother me as it is over to the left to be zeroed, and that is not a product of the way I shoot my rifle. I have had several AR type rifles and this is the first that has been this way. I guess it's not that big of a deal. To be honest I don't even like AR's that much anyways (no I won't sell it), but I still want at least one. |
