First time I seen this gun, nice to see competition offer this form factor, its not a 'copy cat' anymore than a traditional stock bolt action rifle is to that of another with traditional bolt action.
I've gone thru my regulator fad, and while I still respect and adore them, in many ways I much prefer the simplicity of the unregulated pcp. The plenum volumes on tap, in many cases if you add up unregulated AND regulated volume in regulated gun you'd come out with a more powerful gun with plenty of volume for a very flat bell curve over a very usable (albeit smaller) pressure range. Regulated to me only appeals to the high shot count crowd, and the "I must have only 1 fps spread" crowd shooting 100m BR, but for the average pcp user, unregulated is probably a better fit, not sure why regulated guns are 'a must' to so many people in the pcp crowd, I certainly cannot get on that bandwagon. There are pros an con's for either, but tuning a flat unregulated curve is much more an art than tuning a flat regulated curve, much respect to any manufacturer who puts in the research and development to produce long, healthy unregulated bell curves...not many tuners out there can say "I extended X gun's unregulated bell curve by Y shots WHILE increasing/maintaining energy output!"
To that long winded note, I see what looks like a plenum similar to that of the impact/prohpet in the butt stock / rear?
