I'm selling my GBBR converted ACR. Will come with one G&P Pmag that does not leak. It works without issue, both semi and full auto. The only thing wrong is the buffer rod is broken where it locks onto the bolt carrier group so when you take it down for cleaning the buffer rod will fly out if you don't catch it, but this doesn't affect its functionality. The bucking is a little old too but still works. I'm selling it for 250 or 300 if you want the original aeg lower, gearbox shell and all the stuff to put it back to an aeg minus the guts to the gearbox. (Originally the PTS ACR not the A&K) Buyer pays shipping. PayPal users pay fees, money orders also accepted when shipping.
