The ARCHWICK Hop Up Unit is as factory installed on our MK13 Series Sniper Rifles.  You can also buy this Hop Up unit as a standalone upgrade for your VSR 10 or clone sniper rifles.  CNC Constructed from a solid billet of 6061 T6 Aluminum, this hop up unit is precise, and features rich.  Dual BB Detents prevents double feeding and proper BB centering inside the hop up unit and a precision barrel sleeve securely holds the inner barrel in place.  True TDC design allows you to adjust the hop up from the top or bottom side.  Our patented design exerts direct pressure on the hop up nubbin (or oversized plate) in a straight and vertical top to bottom manner, vs. other designs which pushes the nubbin backwards as top pressure is applied.  We also include an oversized pressure plate for use with heavy BBs (0.40 and higher), and also our well regarded 60 degree silicon hop up bucking.
