Knight's Armament Airsoft have come out with a very sexy looking suppressor that has a quick detach function and will make anything that it is attached to look like a beast.

Inside is an ordinary AR type flash hider with points for ball baring placements so that the suppressor can be attached. There are different versions out there. There two of regular length and 2 for CQB. Both of which either attach to a CW or a CCW 14mm thread which fits a lot of systems out there.
