That's what I got. I just bought a folding stock to lock and pin. I like the folding stock more. Get a different length of pull as well. As far as the mini magezine it came with. Ill just rob the follower out of it and use it in a gi 20 or 30 round preban mag. That little magezine gets stuck and doesn't fall free. Also got a cut.down and pinned pmag. May get another soon. I love it.
There is a thread that says all ACR have a safety problem which has deterred me from buying the gun. Apparently when the switch is in safety mode the ACR will not fire, however as soon as the switch moves slightly the gun will fire before the switch is engaged in the "fire" position.
