MK23 TDC hop-up - set [Hades Airsoft]

Works great and high quality.
Even though the black part is 3d printed it looks and feels very sturdy.
the blue tensioners come in different heights to acommodate different buckings as well.
Will definetly buy again if I get another mk 23!!!

It was easy to install following a youtube video, completely transforms the out of the box stti mk23 into a much more accurate pistol, This and a new bucking and the mk23 shoots like a laser. One of the best low cost upgrades for the replica

It fitted perfectly in my TM mk23. And a very needed upgrade for the longevity of the replica as it's best to zero the hop up between games.
My first complain is that it's made out of 3d plastic which shows a lot of different and looks a bit of in terms of asthetics (the strength of it was the same or more of the plastics in the hop up system of the replica) when for a similar price other brands aren't 3d printed and looks more like part of the replica.
My second complaint is that there wasn't any step by step of how to do it. I had to search the web and find similar videos with different products so in the end get an idea of how to do it.

Finally my ASG Mk23 behaves like a real airsoft pistol. If you get one change your hopup bucking too because at least my OEM was useless. I do have some minor gripes too, first of all the unit just clips on, I hope it will stay put and secondly, well it's a 3D printed part, it doesn't look as good as for example an injection moulded piece.

It works really good. I only noticed a slight increase in the noise produced by the shot, but I think it's normal.


I would have liked to have instructions on the assembly, but nothing that with some videos on YouTube you can't do even without experience.

Product came exactly as described. Great design - technically better than original. Very easy to mount - it takes less than 3 minutes to assemble. It fit my Mk 23 perfectly. Hop-up rate is set with a hex key. Setting is very sensitive and precise and is done from the top of the housing.
Great product - I hope it will last as long as original.

For the price it is a great value. Only one thing tho: the tdc screw will loosen sooner or later. In this case sooner it is. It's just the plastic and the construction. Tell the 3D printer guy to make it a bit better :D

While it's a pit pricy for what it does, it works albsolutely perfectly and flawlessly, and the additional nub inserts make it easy to fit to your chosen hop up rubber patch rubber thing. Pretty much a must have to use heavier bbs in the st23!

Best upgrate you can do for your mk23. It make it easy to adjust on feeld and precise. You don't need to pull off the glider to adjust. Also change you bucking to make it perfect. Now its silent and accurate.

At first I thought it looked cheap, but the performance was amazing. Right away after a quick installation, no additional upgrades, my cheap ST23 shot lasers at long range x_x. The concave nub pieces are great for fitting for your specific hop rubber. I used a "stock" ML green rubber that came with the gun, so the largest nub was perfect for me. A great product! Price seems a bit high for a 3D printed item, but it works!

Super easy to install compared to a I-Key, just take out the default hopup and wheel. Have not tested all the different spacers, but works much better than the stock STTI hop. A quarter turn is enough to hop .28bbs, no more than a half turn for heavier BBs.
