TDC Trolley with M-nub (R-Hop & Flat-hop) for Retroarms Hop-up Chamber
$14.99
The TDC (Top Down Centre) Trolley is designed for the Retroarms Hop-up 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 Retroarms Trolley works in unison with the Flat-hop and Maple Leaf Super Macaron MR-Hops.
Improved Trolley Wings
Modifications on the slide bars on each side
This ensures a tighter fit onto the chamber to achieve an absolute Top-down-center hop onto the R-hop patch while preventing an side to side movements!
Imporved trolley Length
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.
The Solution
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.
Precise Manufacturing
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.
FPS Increase!
Enhanced Air Seal at the Hop-up Window
The M-nub once installed will fill the hop-up window agaisnt 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.
A Step ahead of others
Gain the Competitive Edge
For all the moving parts of the TDC trolley we recommend to apply Airsoft silicone grease to make things mesh smoothly. This includes the bottom of the M-nub, the wings of the trolley and the top of the trolley that interconnects with the hop-up arm.
Tailoring to your Gun
Tech Work For Successful Install
For the best installation, we recommend to apply airsoft silicone grease on all the moving parts to ensure they mesh perfectly. This includes the foot the M-nub against the bucking, the side wings of the trolley, and the top of the trolley.
R-HOP | Flat-Hop | Macaron
The Best Accuracy In Airsoft
R-hop is arguably one of the best accuracy mods for an airsoft rifle. The distance and consistency is that can be achieved simply cannot be ignored. With our the TDC trolley it gives the best hop-up applied on the R-hop patch so the BB can gain the most exposure on the R-hop patch, yet smoothest (less erratic) acceleration before it leaves the gun.
