As I said in the now infamous ,"Sniper SKS" thread, I recently scoped my Bushmaster AR-15. I took it to the range and was getting beatiful groups of 1" or less at 100 yards, BUT after I started shooting more rounds I noticed wandering groups:banghead: . Grouping would either be super tight, or look like my AK at 50 yards . Most groups were shot slow fire 3 rounds at a time, with time for the barrel to cool in between. The wind was very light, and I even waited for gusts to slow to a minimum before shooting. The ammo was 55 gr Winchester Q3131 out of a 1/9 twist barrel. With the iron sights I can group under an inch at 50yards all day if I do my part. Does the loose fit between my upper and lower some how effect the accuracy with a scope more than iron sights? When I look through the scope, I can feel the lower kind of wiggling below the scope, and since my cheek weld is there, I assume it would effect where the cross hairs are in relationship to my eye changing point of aim and impact.
The scope is a BSA 1/8" click at 100 yards, 4-16X40mm illuminated reticle type. If anybody has a cheap fix to get rid of the upper and lower receivers play/slop, please let me know. I was thinking about getting one of those little plastic things that you place at the back of the lower receiver that sits under the rear take down pin, but then saw that the front pivot pin wiggled too. I am going to the dollar store to try and find something to place between the receivers that will minimize the receiver play. All help appreciated...

PS-Funny side note- My ,"ban era", Bushie A3 M4gery has a welded AK type muzzle brake and not the regular gas block, so mounting the scope to the upper receiver placed the scope directly in line with the front sight base. The guys at Academy that mounted it for me didn't think it would work that way, but I explained that with the magnification at or above 4X, the scope will focus beyond the sight base and the sight base will blurr out and not show up at all. Sure enough, I was right .
