Heya guys. I'm pretty sure someone heres (Daryl?) brother builds exceptional muzzle loading arms, and my question is this:

If one buys a pre existing lock, how does the trigger assembly all connect etc? Does anyone have any photos of a build from scratch? (with or without pre made lock)? How does the barrel attach to everything, whats the end of a muzzle loading barrel look like ("chamber" end?)? Whats hidden inside the wood behind the barrel and where the trigger goes?

Cheers guys,
Ash.
