Crosman just made a press announcement for their latest M417 Pneumatic Air Rifle which looks a lot like an M4 assault rifle.
Although it looks like a semi auto, under the hood is a multi-pump pneumatic system that requires pumping between shots, you can pump just a few times or several to get right up to 625 fps with 7.9 grain pellets so I am assuming this one is not coming to the Canadian market in it's current configuration. By the way you can also shoot BB's by loading up to 350 into the BB reservoir located on the side of the receiver, while an 18 round track feeds the BB's for shooting.
Some other interesting points to mention are the adjustable rear stock and windage adjustable, dual aperture (2-position), flip rear sight, and elevation adjustable front sight that can also be removed entirely for alternative sighting like a red dot or scope.
The Crosman M417 - M4 styled pellet and BB rifle uses a polymer stock, receiver and forearm and sports tactical rails for mounting accessories in several locations. MSRP is right around $119.
Here 's to hoping for a Canadianized version some time in the near future...
