Parts - if you end up needing any - they are hard to find, as it was not as large of a production as the Hawken and Renegades.
They were purpose built for the PA round ball season, and twisted slow to match the patch and ball.
Single trigger - that is workable, but not stellar.
It's a "short" half stock to me for a balance and carry, always felt very muzzle heavy in the rifle version, but the carbine was pretty nimble.
