Congratulations on the new rifle. I would hope you post pictures of the block, action, and breech plug. I am kind of interested in one of them as well. I have only seen pictures of them but they look real nice. I think I would go with the stainless steel model but that is just personal preference on my part. I will sure be looking forward to your range reports. The only reason the KP-1 and the Triumph do not interest me is I have no need for center fire rifle barrels, so I see no reason to invest into something like they offer. Although I could go that route, sell off a lot of center fires rifles and then just get a couple barrels...
You want a great scope for that rifle and not spend a lot of money, take a look at the Nikon Pro Staff in 2-7x32mm. It is a shotgun/muzzleloader scope with excellent eye relief and great clarity. I have one on my White Rifle and love the thing.
