Strange you should mention scopes lol. i have been looking for days and i am going to buy a bushnell banner dusk to dawn 3-9x40 200 MZ scope, to mount on my Triumph. there $ 79.00 shipped, this is a 200 BDC scope with 6" of eye relief made for muzzleoaders.the reviews on all the dusk to dawn scopes are excellent.we encounter longer shots here or i would go with the 4x32 simmons pro diamond like SEMISANE mentioned.going to give it a try and if i don't like it i will send it back.
