Hadron Mk23 M-TDC Hop Up Chassis

The MK23 M-TDC hop up chassis by Hadron Designs is probably the most popular and effective upgrade you can do to your Tokyo Marui or ASG MK23 pistol. It replaces the outer barrel cover and you will need to get the H-plate and adapter plate to get the full set up.

They drastically increase the performance of your hop-up by putting pressure directly down on the hop rubber and increases the amount of pressure compared to the normal hop wheel giving you a greater choice of heavier BBs and a more consistent flight path.

To install it, simply remove the outer barrel assembly, unclip the outer barrel cover and remove the spring. Open the hop unit, remove the hop wheel and place the H-plate (sold separately) under the metal hop arm and put the hop unit back together. Then place your selected adapter plate (sold separately) into the M-TDC hop up chassis and clip it into the place where the old one was and you’re good to go.

We recommend when you take it apart to take the opportunity to replace the inner barrel and hop rubber for an upgraded set.
