Other than bad projectiles, the only other thing I can think of is bad powder. Has it been stored correctly, or is it old?I think John was asking, “Are you sure the manufacturer built a 1:8 twist?” Yep. They did.
Changed via Hornady LNL powder measure with the rifle powder drum. Weighed each charge on Lyman digital scale. A2230 seemed to meter well: it was pretty fine. I doubt I could have a light load because it wouldn’t have cycled the gun. (See my OP re: start load didn’t cycle).
That target had a mix of me and my not-as-skilled son shooting Win. M193. You’re right, there’s no obvious group.
Iron sights. Midwest Industries combat fixed front sight and UTG A2 style fixed rear mounted on the Pic. rail.
If your concern is that the AR is somehow fundamentally flawed, you’re off base. Here’s a picture of my Dec. match target at 100 yds: prone slow, rapid, and off hand. It zippered 8 rounds into a strip about the width of a ruler during slow prone. If I do my part the gun does it’s.
