The TDC (Top Dead Center) system regulates the hop-up by applying direct pressure from above onto the hop-up arm. Compared to conventional solutions, it eliminates unwanted play, offers more sensitive adjustment and a wider adjustment range. The regulator is made from a CNC-machined aluminium alloy and consists of a base and an adjustment ring. Its low-profile design does not interfere even with larger scopes equipped with sunshades. Installation requires drilling a hole into the outer barrel at the position of the hop-up arm. On selected hop-up chambers, the device can also be screwed in place instead of being glued.
Direct pressure from above onto the hop-up arm provides smoother, more precise and more stable adjustment than conventional levers.
The adjustment ring offers 26 indexed positions per revolution. Each position corresponds to approximately 0.02 mm of travel, while one full revolution provides 0.5 mm of travel.
The regulator is made from a CNC-machined aluminium alloy with rounded edges that reduce the risk of snagging on equipment.
The built-in spirit level helps keep the rifle in the correct position and reduces errors caused by tilting during shooting.
In most cases, the regulator is glued to the barrel using instant adhesive. Selected hop-up chambers also allow secure attachment using the included screw.
