I think it's going to be a lot of fun to use, but it's only .6J from what I've read about it, that's like 255fps? So it won't be very competitive in an outdoor environment, and in CQB you won't be able to use full auto.
To me that kinda nullifies the whole purpose of it. If you can only use it on semi at 250fps then even in CQB I'd rather have a pump action with a bit more oomph because side stepping shots at that speed isn't remotely difficult, even at 20 or so metres, and at that price point I'd want something a bit more interesting to look at... 'cos it's just a box really. I like being able to fiddle with controls, bolt locks, releases, charging handles, sexual metallic noises etc etc.
It's looking set to be into the £400 bracket too, probably higher because it's a big sensationalist thing and the UK retailers are rip off merchants.
If I get the chance to have a go, I'm not going to turn it down. But I wouldn't even entertain the idea of buying one.
I see it more as a successful technical exercise. Now they need to adapt it, improve it, and make it fit into more platforms - Namely an M1014.
