I had to wait for a lock for the kit I bought, sucked, but was not a big deal in the long run. I got over it. Some things, they have been busy keeping up such as late Ketland locks. As for barrels, those are made in runs dependent on size and style. For right now, you are not gonna find anyone sitting on large stocks of parts, for example,...go to Track of the Wolfs or Muzzleloaders Builders Supply's website to check out barrels, see how many of them barrels are "out of stock"!! I'm not sure if sales are so strong that no one can keep up OR that the economy was so slow for the last 8 years that most business's can't risk having that much tied up in inventory, I lean toward the latter since that is how it is where I work. As suggested, give Chambers a call, they have always been good to me and honest about any delays.
