The Tominator of the Pyramyd Airsoft Blog reviews the Elite Force UMP Competition Series version as he stated that there are two versions of this... "If I were in the market for a budget-friendly UMP, then the HK UMP SMG competition series AEG & I would probably become besties. It's a nice little submachine gun with a nice little price.

Some of the external features include a tri-railed handguard, with an ambidextrous sling adapter, which I always find to be a nice touch.  I will add that the charging handle is nonfunctional, but not something I really care about anyway for an AEG, especially if I got it such a reasonably low price like this one's got."
