Panzer AR Twelve Compatable Extended magazines

Hi Alan, That is the "Only' magazine that I have found to fit.

sorry you are having so much trouble I have been looking for a good contact number for PW arms so you could contact them for help but they don't seem to have a site or phone number. Good luck I do suggest that you contact Buds at (859) 368-0371 and see if

Alan, this is supposedly the "Factory Magazine". (CF should be able to verify this at Phone: (704) 774-1102 ) : classicfirearms.com/fedarm-fr99-mag-10rd
