The Project Airsoft TDC Screw took the MK23 market by storm, making it infinitely easier to adjust your SSX303 hop or MK23 Hadron Designs TDC mod. And now we've partnered with TRIDOS.DESIGN to bring you a full metal CNC version
Introducing the Project Airsoft X TRIDOS.DESIGN CNC MK23 TDC Screw!
This screw simply replaces the stock grub screw used to make hop adjustments. Just remove the original, put this one in and now you can instantly make on the fly hop adjustments without the need for additional tools.
Due to the ultra low profile of the adjustment screw it doesn't get caught on holsters when drawing or re-seating either!
Note: Rif and stand not included
