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.

Excuse my grammar. English is not my native Language.

hey Mikus, a very good piece of equipment, I should have bought this a long time ago. this is great

Excellent tool... it is the tool that all of us who have sniper rifles should have, it really makes the job easier and takes care of the cylindrical nozzle when removing it.

Works very well; opens many cylinder head sizes (specially to my custom made cylinders...)
Also, it does not leave any heavy dent marks vs other tools (in my case, circlip pliers).

I also like the wide knurl in surface, as it provides me better grip with my oily hands.
The through hole is also can be used for long screw driver or metal rod to make torque for cylinders that are hard to open
or needed to be tightly closed.

Another great must-have item to your tools.
