It's a laminated straight comb stock with checkering panels. It has a fluted barrel. Barrel is marked Disc Extreme.
It's a Knight Disc Extreme. The 45s have a 1/30 twist. They are nice rifles and can be shot without the disc by using a bare primer conversion. I think they cost about $40 from Knight.
BH 209 works well with this set up. It's worth about $250 - $300 in good condition in my opinion. It may be a Master Hunter with the fluted barrel. If so, it will have MH stamped on the bolt side of the barrel. If it's a MH the value goes up a $100 or so.
