Looks like this thread got moved wholesale from the Optics forum.
I have seen a review by SharpshootingUK here:
Looks interesting. For my purposes (100-600 yds vermin shooting off a bench) a stock with an angled bag riding area to ease elevation adj plus a squeeze bag is the ticket.
I could see someone who shoots WAY out there, in prone, at tiny rabbit-sized targets might really benefit from it. The UK bloke does tend to shoot from hills/hillsides, so I could see adjusting the buttstock may be more ergonomic than readjusting the bipod height.
Plus, as the review notes, that unit is lighter than 2-3 different sized rear bags.
