Description

Here's a drop in TDC of my design, made for CYMA AKs (mine is CM045), not sure about other companies but if the hop up unit design is the same, it should work just fine. The only part you have to take off the gun to install this mod is the dust cover, couldn't be much easier than that :D You'll need: -x1 M4 screw (you have to experiment with its length) -x1 M4 nut -super glue (optional) The assembly is as simple as follows: Put the nut on top of its slot on the inside of the TDC and hold it in place; Push the M4 screw through the hole on top and drive it into the nut until it's pulled into the slot (the nut should stay in place by itself, if it doesn't tho, use super glue); Unscrew both the screws holding the hop up slider; Slide the TDC onto the hop up unit from the barrel side, and push it towards the gearbox; Take one of the slider screws and screw it back in through the hole on the side of the TDC. And you're done! Tighten the screw on top to increase hop and loosen, to decrease it As I said, it should work for all standard Cyma (VFC spec) AK hop up units, but if you manage to make it work in a replica made by another company, make sure to let others know in the comments ;) One more thing, if your stock charging handle doesn't fit with the TDC installed, this one should: https://www.thingiverse.com/thing:4970817
