There are several variants of the model 12s as they have been around for a couple of decades now and as with most products there have been some variants and changes along the way.
Pretty sure you're referring to one of the newer factory "target rifles".
Really can"t comment on that particular variant other than to say it came from the factory with all the right parts to be stupid accurate.
I have one of the older model 12 BVSS varmint rifles in 22-250 that will stack 10 rounds of hand loads into a spot the size of a dime at 120 yards with ease.
