I got a M4 Carbine Handguard and Grip that came off my Preban PWA Commando A1 rifle. They are in good condition. I also have that round ring thing-a-ma-jig (someone please tell me the name) that fits between the collapsable stock and receiver, because i installed a side sling adapter in its place. I upgraded to a Knights handguard and Fobus G27 Grip and do not need the stock ones anymore. Looking to trade these for/towards a 15 round glock 19 factory mag.
