Really nicely machined part, super adjustable for different cylinder heads, cracking little tool, I can highly recommend it.

Great little tool for tightening & untightening different makes of cylinder head, the only improvement I would make is a double flat edge groove on the opposite side for those cylinders without holes.

Smart little tool! No more fiddling with tweezers and pliers :)

The Wrench beats the problam that you have to jam a pair of liers into your Piston. the Wrench ist nicely bult and feels nice the only thing i can say is negative ist the changing of the pins. There are slits for a screwdriver but my entire Airsoft Workshop has no Screwdriver that is thin enouch to get in there. so grab it softly with Pliers or try to screw it loose with your Fingers, just don't loose them they are pretty tiny. Would love to have the ability to buy these screws/pins as a Spare Part. Other than that.. I love it.
