Matrix CNC Aluminum One-piece Hopup Body for M4 / M16 Series Airsoft AEG Rifles
by Tomas P. Date Added: Thursday 26 May, 2011
I placed it in my Matrix M4. Works great!! NOTE: It does NOT come with any accessories. It is just as the picture shows. Don't forget to get the gears and the bucking separate.
