scopes are okay mounts are garbage, I had one for a while then had sold it to a buddy who then ran it with good mounts on a Winchester Highwall in 40/60 Maynard... no complaints so far .... good mounts run about $450.00 USD,,, Montana Vintage Arms, RHO, or DZArms you will need to find a Pope Rib because that DGW / Tasco scope has no rib .. another place is Steve Earle Products . I would guess that you do not want to spend that money on a muzzleloader that scope has to be able to slide forward under recoil ,then you pull it back before every shot.
There was a Safari Arms 54 on GP that had the shorter brass scope that reminded me of a Winchester style series "B" scope. MVA has that model of scope
