Thanks: all good points. I haven't checked for parallax but will first chance. For me, parallax problems give randomly large groups with inconsistent fliers at various points. The RR always throws the wide shot on the first shot hot or cold. Does the same almost every group including some shot by an experience competition shooter friend.
Also, I will try shooting groups single loading as a test, and I will give the chamber an extra good cleaning.
Wont be selling the rifle. This is my first AR and working out accuracy problems is part of the fun for me. My purposes is PD shooting and possibly local matches.
More tips and suggestions will be appreciated.
if you get two groups from single loading and then magazine fed, maybe replace the barrel. I had a bushwacker once, bought during one of the panics.. the rear sight had to be screwed to one side to get the rounds on paper at 50 yards, I figure they just built a POS and shipped it, that one lasted a month IIRC.
I wish I could be positive and blow rainbow smoke but at my age, I just relate my personal experience as it was.
