Airtech Studios TDC trolley for Tokyo Marui SCAR-H / HK417 series

The TDC (Top Down Centre) Trolley is designed for the Tokyo Marui SCAR H & HK417 chambers to incorporate the traditional usage of M-nubs which works perfectly with the R-Hop patches to achieve an improvement in accuracy and consistency from shot to shot. 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. The improved trolley works in unison with the Flat-hop and Maple Leaf Super Macaron MR-Hops.

Modifications on the slide bars on each side :

• This ensures a tighter fit into the chamber to achieve an absolute Top-down-center hop onto the R-hop patch while preventing an side to side movements

Increased Trolley and M-nub Length :

• The contact area of the front is increased by 0.5mm, from 4.5mm to 5mm to cater for most Inner Barrel window sizes so that the pressure is applied evenly across the whole R-hop patch. This will mean more even surface area that will rub onto the BB when it passes through. Expect consistency and accuracy to be improved

Superior M-nub :

• 3M adhesive incorporated at the back of the M-nub for optimum contact on the Trolley foot. This is a strong bond, however, is flexible and may be un-stuck to be re-applied later. The M-nub is manufactured with memory properties to mold into the perfect shape to push your R-HOP patch

Tight & Snug Fit :

• Once the TDC Trolley is installed onto the hop-up chamber, the whole unit can then be placed back into the gun. The part will not interfere with the operations of the outer barrel or dust cover

Enhanced Air Seal at the Hop-up Window :

• The M-nub once installed will fill the hop-up window against the bucking and once hop is applied, the M-nub an trolley will seal the window into a air tight chamber preventing and air to escape. This will firstly increase the FPS output of the system, and secondly have a consistent FPS. Both combined will allow the BB to travel on accurate trajectory

Ultra-Tough Polycarbonate :

• The TDC Trolley 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

Includes:

• TDC trolley
• M-Nub

The hop-up chamber is not included.

The color of the parts may vary depending on production and batches.
