"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!

"Second Review:

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

"Great piston head. Aluminum design means it won't break (as easily) and the ports allow better air flow into the cylinder. The O-Ring it came with is AMAZING for compression.

"High quality piston head. I had no idea how to put on the bearings, but still operates without them.

- Made from aluminum, much more durable than plastic ones.
- Ported
- Good O-ring
- Comes with ball bearings (didn't install mine, D:)

- None to list.

"Perfect piston head for a perfect price.

I've shot over 15,000rds on this head, running 470 FPS at 22BB/s.

It'll last you, Well worth it.

Very satisfied.

"What can I say? I've beat the crap out of this piston head with an M125 shooting 400-415 FPS @ 900 RPM and it continues to hold up after 20k rounds. It will probably outlast everything else in my gearbox. Buy it.
