I picked up this 22cal semi auto training rifle and it has gills aloong side the bolt. Its a semi auto in 22lr and a bolt rifle in 22l & 22s rounds. You push in the bolt knob horizontally to make it shoot like a bolt action. There is a 20 page post on parallaxbill's C&R forum about these two rifles that are actually twins one being a military trainer and the other the civilain rifle too. If you search for these two rifles they seem to run between $1,500 to $650. I just picked up the US Martial 22RF book about all the military training rifles and this one isn't in it I guess they migtht have missed it. She looks like a Garand.
