New hereabouts, I just got a 99MonteCarlo (never thought I'd own a Chevy) in .308 Win
S/N A6120xx, too new for an LBC
22" Westfield barrel with ramp front & folding rear sights
Schnabel-less fore end & pistol grip stock with big/little diamond checkering impressed (but I'm not)
Gold trigger, pretty color case
Tang safety, jeweled bolt
Curiosities:
Steel vs. brass round counter rotor
Letter "Z" deeply stamped below the normal "MODEL 99M" stamp, below the front scope mount

She's a looker, hope she's a shooter, hogs will find out this spring

My guess? '72 99DL. How did I do?
