TDC hop-up chamber MAGNUS™ is an extremely precise polymer chamber from Specna Arms, introduced with the PRIME series. It features a TDC pressure system, a special structural element of hop-up chambers that allows optimal pressure adjustment on the BB through the hop-up rubber’s nub. The pressure is applied directly above the barrel window, perfectly perpendicular, rather than using a lever at an angle. This enables players to achieve greater shooting accuracy and a stronger hop-up effect with heavier BBs for each individual shot.
The chamber comes equipped with a Helium™ rubber featuring a Flat pressure system. This is a rubber with no nub, but it is completely smooth inside. As a result, it eliminates the issue of BBs curving due to incorrect installation while increasing the contact surface between the BB and the rubber, effectively covering the entire pressing segment. This results in higher BB rotation, leading to greater range and accuracy and allows the use of heavier BBs.
