There’s something on the Grip.
It is, you can tell because the receiver slides back into the gap at the grip.
It also has a compensator, not a flash suppressor.
No it doesn’t. Second mag looks like a 60 round magazine. First looks like a 40 round magazine. I wonder how many rounds you can fire (continuous fire) before things get so hot the weapon jams? I also wonder how many full auto weapons the shooter had? Fire until jammed and then move to the next?
How did a “not a gun guy” organize this and why?
