Sounds like you're more aiming for an all around repair parts kit. Not designed as much for the individual repair, but for someone who would be repairing many rifles (thus the 5 complete LPK thought). I like it. I would definitely get something like that.....even though technically I've already made up something like that for myself. Really, there's only so many parts involved, that a decent divided parts bin from Grainger (the 3 drawer steel slide-out type) serves as good storage. Then you just have to fill it with all of the parts.
Something like this. You can hold all of the parts that you can think of. Short of barrels, upper, lowers and stocks.

I like the idea though Pat. I would definitely throw in bolt repair parts, along with lower parts. Am I close to what you were envisioning? Without maybe the steel drawer bins?
