The file 'A&K Airsoft M60 & Mk43 Chronograph Feed Tube 3D Printer Model' is (STL) file type, size is 1.0MB.
Easy feed port extension for the A&K Airsoft M60 & Mk43.
Chronographing these guns is a pain if your airsoft site requires you to use their BB's to chrono. Feeding a couple BB's in while holding the gun sideways is a chore thanks to the box magazine hanger.
Not anymore. Simply screw this adapter in and add BB's. No more trying to drop them gently into the port from up high. It should also hold enough BB's to do a reasonable RoF (Rate of Fire) check without running out of BB's.
Print with the knurled (big) side against the build plate. No supports needed.
For those wondering, the gun side threads are M12x1.5.
Update 5/19/2024:
Model updated to V2, made the center hole 6.5mm instead of 6.2mm to account for hole shink in FDM printing.
