ugh. Adaptors.....
I have one on my Charger pistol and it's not too bueno. But if it's your only option, Harris is the choice. Accu-shot out of Woverine supply does adaptors and bipods, but they're big money.
That said, if you go with the Accu-shot stuff from Wolverine, check out the Fab Defense dovetail AR grips. They're muey bueno.
So........... IRunGuns is having a big AR sale.....
