This thumbscrew is made in collaboration with Project Airsoft. It replaces the original screw on your pistol's TDC cover and is fully compatible with:

  • Novritsch TDC cover for SSX23 and SSX303
  • Hadron Design's TDC cover for MK23
  • Most other TDC covers with M4 size threads

It's manufactured with a slightly oversized M4 thread so it wouldn't turn by itself when installed. It also comes with a dab of pre-applied thread glue to provide even more friction.

The screw is made out of anodized 6061 aluminum and has laser etched indicator for hopup adjustment direction. Thumbscrew has knurled sides so you can easily adjust hopup even with gloves.

It's super low profile so it doesn't get in the way of fibre sights or prevent you from using a holster.

It's a perfect upgrade / fix for SSX303 - no more scatching on the inside surface of the extrusion and no more flexing due it it being much shorter which will means you can easily apply more force when adjusting without worrying about destroying the TDC housing.

⚠ During the initial installation the screw can be a bit tight - we recommend screwing it in and out a few times to make it easier to turn.

This is it

Small. Convenient. Easy to use. The pressure you have to apply to adjust the hopup is just excellent. There's no way that it would adjust on it's own when you randomly bump into something. Very nice piece of upgrade.

the devil is in the detail

In the case of conversion, this little devil does a giant service. Must have for your mk23 with TDC. Hop up setup was never been easier. Thank you Tridos!

Great performance…

…as well as accuracy and consistency with the Flamingo bucking 50 version in an SSX23 and the 60 version in an SSX303, both with the upgraded hop arm and mini thumb screw - highly recommended !

Adjustment made EASY!

It doesn't get easier and more convenient than this. I have the full Nano Carbine Kit on my SSX23 and a 1-4x scope so I have to remove the sight to use the allen key and grub screw. With this I just reach up with my finger and adjust while keeping mig target in sight. A small but very nice upgrade. Worth every cent! //Esox


What else would you use? serious question.

Some people would rather use a grub screw and an allen key. Those people get shot when adjusting their hopup.

I just move my index finger from the trigger and fondle this thing a little and my balls go where I want them.
