16" M4 Countour

The F-17™ Series is the worlds first gas piston rimfire rifle. It shoots a .17 Winchester Super Magnum Rimfire round that operates at 33,000 PSI while producing velocities up to 3,000 FPS. This design was created to be safer and more reliable since it uses a rotating locking bolt and piston design. The F17™ series is also exempt from many restrictions placed on centerfire rifles in states like California.
