I've been reading the last few issues and I've been following their Frankenstein gun project for at least that long.
It looks like a lot of work, since they're modding off the shelf items. I'm interested to see how it'll turn out. But for now it looks like they're just trying to spit our as much BBs as possible.
The last issue I read had them trying to achieve a shorter piston stroke so that they increase the ROF. Of course they had to sacrifice their FPS to do it. I'm just curious to see if they can balance superior ROF with a decent FPS. ROF is all well and good, but if I'm stuck with a stock spring, then forget it. Although for them, being in the UK, they probably couldn't field that thing with an M120 anyway.
