Sometimes you see a clever design, something that is so obvious, and the answer needed by so many.
MK23 TDC TOOL.
In order to get the best in range and accuracy with our MK23 pistols, a lot of us use the Hadron Designs TDC mod, the stock adjustment with the SSX23 or something similar which allows us to make minor tweaks to the hop using an allen key quickly and easily. But this means you need to carry an allen key with you in the field which can be a pain...
Introducing the Project Airsoft MK23 TDC Tool! (Can ALSO be used to adjust SSG96 hop!)
This tool handily attaches to the pistol without any modification by utilising the thread on the trigger guard which was originally intended for the LAM unit (but who uses that). Just screw it in and you won't even notice it's there.
Then, when you need to adjust your hop, just unscrew the tool, make your adjustments, screw it back in and you're now more combat effective.
The body of the tool is plastic and the allen key is metal!
