I have a chance to purchase a 12 bore BSS Sidelock 28 inch barrels for $3,500. I was wondering if you gents had any opinions or information on this gun. It appears very few were made. It is choked Mod/Full so I would probably open the chokes some. It also appears unfired. It would be used primarily for upland game. Is this something I should jump on or pass? Thanks.

Buy it

Yes, they normally go for $4,700 or so in good shape.

Rugged and smooth swinging shotgun for the money.

Buy it, do not change the choke since you will destroy the collector value and treat it as an investment. A standard BSS goes for 1200 to 1500, get one of these and shoot it and re choke it since it won't drop the value as much as the side locks

I shot one many years ago, and it was a sweet gun. I'd buy one in good shape if it became available near me. As I recall, they listed for around $ 2200 new over 20 years ago, in the Guns and Ammo Annual. You're getting a great price. Good hunting!
