Tridos SSX23 / MK23 Mini TDC Thumbscrew

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
• 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 anodised 6061 aluminum and has laser etched indicator for hop-up 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.

⚠ During the initial installation, the screw can be a bit tight - it will wear in over time
⚠ It fits SSX303 but stock screw is overall a better fit than this thumbscrew
