No, according to RedWolf, the second piston takes off very little fps, something like 3-4fps. Considering how much cylinder volume goes to waste in most guns, it's not a surprise.

Honestly, people complaining about this being a poor blow back design is being ridiculous. This isn't a real blowback design, all it does is cycle the faux piston. It's bolt cycle, not blow back.

Is that worth holding against it? Not really, especially on top of decocking forward assist, accurate fire selector and radius'd cylinder window. IIRC, the bolt catch also works.

A lot of previous designs have attempted to do bolt cycle. Even TM has recently produced one in the form of an AK. However, the G&G design is probably the best one out of all of them, because the movement actually matches the gun firing, rather than the piston drawing back.

If people want a real blow back gun, get a real blow back gun. This isn't it, no sense in complaining about it.
