Airtech Studios TDC converter kit for Tokyo Marui M4 NGRS series

TDC conversion kit designed to fit the stock Tokyo Marui M4 NGRS hop-up block to improve accuracy and reliability with every shot. The TDC Kit is manufactured through plastic injection molding using polycarbonate as the material which is lightweight and tough against the stresses while installed into the hop-up chamber.

Perfect Top-Down-Center Hop

• Once installed you can obtain the fully functional TDC hop alongside the advantages of keeping the original hop-up unit designed for the gun which can prevent situations like misfeeding or double feeding

The TDC Bracket

• The main bracket: This fits onto the original Tokyo Marui hop-up chamber and acts as a medium to guide the trolley moving vertically up and down to apply hop-up. It is designed to restrict the movement of any other axial directions, and limit only on the vertical axis.

The Vertical Trolley

• The trolley is fitted inside of the bracket and can only move up and down the vertical axis controlled by the bracket while using the walls of the original chamber to prevent the trolley from swaying left and right.

The M-nub

• The M-nub ensures an evenly distributed force is applied onto the bucking down to the RHOP patch. This in turn ensures the patch can maximize its appliance on the BB for the most stable and uniform spin for the much desired R-hop performance. This is stuck onto the trolley via a strong 3M sticker.

Modified Hop-up Arm

• Lastly the modified arm is used to apply the desired force onto the trolley and then the R-HOP patch.
