you didn't tighten scope and barrel and shoot another group?I'm glad I saw this thread.
I bought my first AR-15 a while back. I'm not a huge AR-15 fan, but I wanted one for the experience. I bought a Core Rifle Systems M-Lok Scout in .223.
The trigger was not exactly a Timney, so I stuck a LaRue in it. Not a match trigger, but more pleasant than mil-spec.
I had seen Internet people shooting this gun well. I picked up a bunch of Australian Outback 55-grain Sierra Blitzking ammo, and I shot prone at 100 yards. The target I am posting shows what happened. I quit and went back inside, wondering what was going on. I thought maybe the scope had come loose. The first 5 shots went into the bottom-left target, and they were pretty clearly sub-MOA. Then I shot another group, and the rounds went all over the place.
It sure looks like the gun can shoot, and I have no problem shooting sub-MOA with my RPR, so I don't think I'm hopeless, but obviously, something is amiss.
What on earth can I be doing wrong to shoot two groups this different?
I was not expecting insane accuracy, but this is horrible.
