About the HK UMP 400 Rd. Magazine:

Firepower in a close quarters environment, that's what the UMP is all about.  Umarex offers a 400 round magazine that works with the competition series and elite series UMP Electric Airsoft Guns.  This magazines gives you all of the ammo capacity you need during those long fire fights.  Do you play in a close quarters (CQB) field?  Sometimes you can get into intense firefights where just one magazine will not do.  Having a high capacity magazine will ensure that you can get through those firefights and come out on top.  When using the magazine, open the trap door and fill with high quality airsoft BBs.  Then wind the magazine until you see BBs come to the top of the feed port.  After the BBs are at the top, wind an additional 10 - 15 times to build spring tension to fire approximately 50 BBs.  Once your gun stops firing, wind the magazine again to fire additional rounds.  Repeat this process until the magazine is empty.  This magazine is manufactured to scale of the real UMP magazine.  It features the .45 auto engraving that is on the real magazine, and also has fake bullet grooves molded intot he side.  It is manufactured out of a high grade polymer and designed to be used with all high quality 6mm airsoft BBs on the market.  Use the Elite Force brand BBs for optimal performance.  Are you looking for a place to store your extra magazines?  Check out UMP / P90 magazine pouch by Condor.  This is the ideal pouch to hold extra magazines.
