It's a hideous nightmare of a contraption, it's like they went out of their way to ignore the failings of the HR81 - inefficient piggy-back design, needlessly complex, over-engineered and yet dangerous at the same time, and ugly as sin. Then add a spectacularly awkward loading port and routine, plus GAS RAMS, a non-floating barrel and it is something that should be used on design courses as a warning to students. If you compare it to the ProSport, it is a total failing, and you could buy three ProSports for the same price, and I bet it will not match the PS's performance. You could buy an amazing PCP for the same price. Keep It Simple, Stupid!
Fair enough, make a recoilless springer, but this is not the way forward. The Air Arms SR mechanism worked well but could have been improved on for maintenance and that would have done the job and would have resulted in an affordable rifle. I think they will sell about six of them, all to collectors.
