Can anyone please explain what exactly this is, I've never heard of it before and I believe the specification listed by savage are wrong. FVCSR listed as a 21" barrel, They make it ever more confusing with their letter designations. How does it differ from a standard B-22 FVSR? I know it's a 22 magnum, but the rest has me confused. I would like to buy a B-22 FVSR 22 mag rifle with a 16" barrel.
