It’s moving into the keep column for sure.
Time will tell.
The 6mm arc in an ar platform has tuning issues as well. (If you believe the internet) I’m not sure I want another problem child.
I’ve n ver had a build that wasn’t 100% from round 1 to round 10,000 plus.
Frustrating.
I understand the frustration .. the straight wall jacket ARs are for hunting so you really are only firing a couple rounds at a time. It’s those of us that like to shoot and want what we build to perform to our expectations or what’s the point. If you stick with the little things like keep the mags loaded at all times the springs in the mags could be too tight you’ll eventually get there.
