(Sold) Top is a Douglas SS 1-10 6XC for a small shank Savage. Guessing 300-400 rds through it. I got it from Sharpshootersupply as a 6BR and had it rechambered to 6xc so it would be a repeater. Measures 24" to the receiver and .820" at the muzzle.

I don't remember is this is a Montana Rifle barrel or Benchmark. I bought it new from someone and had my smith chamber and install on my Rem 700. It's a 1-12 SS and Measures 24" to the receiver and .630 at the muzzle. I'm pretty sure it is a #3 contour.
