The DYE sticky grips will fit the mechanical Piranha frames...but only with some modifications.
Youll need to cut out the hard plastic ribs, found between the finger grooves, on the stickys.
This will allow the grips more room to stretch ove the frame.
Next is some cutting away of the grip itself to make room for the sear release lever.
Thats it...it may sound a tad difficult, but its quite simple once you get started.
Just take your time!!
