Kingdom of Airsoft show their new tool for airsoft maintenance use, the Piston Tooth Rack Jig... "A new addition to the workshop is my custom piston tooth rack jig. This will allow me to take the teeth off the rack of piston with much more precision. The propose for this is to short stroke the piston, or for the piston to be put in a DSG set up.
