"Excellent job Guarder! Superb air seal and fps boost. Would buy again. Fit into my KA M1a1 Thompson like a dream. Thanks Evike and Guarder!
So with this Piston Head, an M140 spring, and 100% upgraded/replaced internals and a compression spread of +/-4 total, I was pushing about 440 FPS with .43g BBs(Madbull).
This combined with a W hold bucking, incredible. It was hitting targets fast, small spread, and consistency.
Unfortunately, the Piston Head somehow tore/snapped away from the Piston's Hold and the entire Piston Head assembly(screw+mount+ballbearings). What's weird is it seems to have just had some kind of suction going on, or something, and it just pulled the screw right out of the piston head - destroying many threads and essentially "totaling" it. The screw was fine, but the inner threads of the piston head were decimated.
What's super weird, is no matter what piston head I use(I've tried lonex, hawk double oring, and matrix now), they don't compress as insanely well as the Guarder did. I'm not sure if it has a special o-ring, or something outside of the standard #14 that most piston heads come with or what... but I'm getting 330 FPS maximum now.
Amazing piston head overall, but it snapped for some reason. So I'm rescoring it to a 4 out of 5, only because of that and really not even know what truly caused it to behave so poorly after maybe 1000 rounds.
"The Good: Shiny, pretty, tough aluminum, perfect seal on my stock cylinder for my JG G36(DMR version) version 3 Gearbox, really helps compress that air very well. Must have.
The Bad: None
The Ugly: None
