Enhance the look of your UMP/UMG airsoft gun by adding this flash hider and mock suppressor kit. The flash hider will attach to any 14mm CCW threaded outer barrel and the quick detatch barrel extension can easily be added or removed with the press of a button. Both parts are fully made of metal and the mock suppressor is also lightweight. Adding this kit can allow the use of a longer inner barrel for greater accuracy and range. Please note that this barrel extension was designed for use with the G&G UMG AEG. It is not guaranteed to fit other models of the UMG/UMP.
