Great rifle and the easiest muzzleloader frame made to modify if the shooter prefers. I've owned Encores since they hit the market. The breech plugs need NO MODIFICATIONS to shoot BH209. Every single rifle I owned or worked on, would shoot less than MOA @ 100yds if the shooter themselves could manage it. In other words, the rifles all shot better than the shooter could shoot them. There's a few well known modifications that for about $35, they'll make it feel like a different rifle.
For the trade........... it all depends on what you have to trade and its worth. Good luck.
