I was more interested in the XM148 launchers! I'm on the fence with the 249. Having to carry a stack of magazines is a bit odd. And you will want a pile of them. Nice for milsim or gbb only events. I imagine the parts get very expensive very quickly. £600 to start, that's reasonable. Then all the bits to make it into a mk1, plus at least 10 mags. Plus some bulbs incase you gas out...
