HK UMP Magazine

This Umarex factory original, high capacity H&K magazine works perfectly with the Heckler & Koch licensed, S&T manufactured, UMP 45 AEG submachine gun. Constructed out of high strength polymer, this magazine holds up to 120 or 400 rounds and feeds flawlessly, even under the most strenuous simulated combat conditions.

*This magazine may not work with other AEGs*
