I received a "hand me down" sako .222 and am a little unsure of the actual model. It just says SAKO Riihimaki on the side of the receiver along with the 5 digit serial number and a couple stamps of some sort. I looked on the sako web site and don't see that as a model listed under their old models section. I'm sure pics would help and I can figure that out if people need it. I'm just curious about what I've got here. I should add, it's a bolt with a three round detachable mag. The mag release is inside the front side of the trigger guard. Thanks.
