The unique thing is the 'adjustable gas system' (although I think it may really be an adjustable RECOIL system - haven't seen the actual mechanism). It would be nice to have a semi-auto 22LR that can function and cycle ALL the available subsonics and so on well.
Not in the market myself, as I have a Ruger 96/22 with an integral suppressor so it will 'cycle' everything and is quieter than a 10/22 of course. (...plus....it's a LEVERGUN, so it's cooler than a semiauto...

Anyway - I'd not seen a 22LR semiauto rifle that had such an adjustment.
