Silent Industries MTW Alpha Hop-Up Chamber (Inferno) Iron Sights Essentially the ZET system offersLet us show you the most feature packed hop up ever made! NOW BLACK ADJUSTMENT WHEEL IS INCLUDED! True TDC To get the most consistent pressure on the bucking through the hop up settings, we had to include TDC. This means the nub can only move in up & down motion. The TDC trolley we include is made for nubs, so you can use your desired nub. We recommend using our Black Nub, ML Omega or similar height nubs, because our system was optimised for it.
