That is not a Sako Mauser.
I agree this isn't a Sako Mauser. It is a Sako. It does have dual locking lugs and a claw extractor. It is a control round feed. I'll call it a Mauser made by Sako.....
I have had a few over the years, and without ecception they all had dinky wee Sako extractors and were push feed with manual ejection.
