Just making sure my thinking in that was correct. I think everybody but the ATF thinks its a stupid idea. Looks as though the cz kit includes the magazine parts. Cz custom makes a barrel, thread adapter which i guess wouldnt count but they make a flash hider also base pads right now. If the mag parts were really cheap i wouldnt think twice about just equipping all mags with them but their base pad is around $30 each. Im on the fence weather or not to get an evo and go this route. Seems like its going to be pretty expensive, the manticore arms stock is sexy though.
