Here it is. Garand Thumb with the H&K MP7 in all its glory. You probably don't need mags for this super rare submachine-gun from Heckler and Koch, but you should shop at Gunmag Warehouse for all your other magazine needs. The 4.6 caliber is hard to find, but there is a lot to love about this little submachine gun. It's also better in real life than in Call of Duty.
