Here are some of the specifics.
Basically an Encore with some add ons. I like the design of the ramrod. Not so sure about the swing hammer or stock. I do like the idea ofa 90 degree breachplug.
Still is the same basic design on the reciever. If you like the fluted barrel and front end, you will probably be able to get that for your old reciever. The old barrels will still interchange.
