It's taken about 40 years of development and tweaking to get the AR to run right. Let's just buckle up and see if we can get a short M1A to run.
I've only personally seen issues with the magazines in the M1A SOCOMs. And I've had several through my Carbine Courses. I think they are awesome. But one thing they are not, precision rifles. If you can live with a 3" group at 100 yards, you can live with a SOCOM.
I just want it more consistent... make it a 1" group and I'm in. Unfortunately, I've not seen one do a 1" group.
