I have one of these. I won mine in a comp in airsoft action magazine. Out of interest I have been checking stores for their sales, but they all seemed out of stock till just recently, so I wondered if it had a recent release date. I couldn't get mags until last week either.
It's a cracking bit of kit, too. Out the box, it was tearing holes in corrugated cardboard at 20 yards. I just downspringed it, which took literally 2 minutes. You could use it in a woodland game, switch the spring and go cqb within minutes.
