Randall, I'll run this idea past my gunsmith in the morning, Once I get a hard price on the work he'll be doing, I can then run some simple higher calculofragilistics on my Ultra-Brain 9000 Super Mini Micro Thinkmotron Desktop Personal Robo-Abacoid and see how much it'd cost for me to get the parts from M&A and having my gunsmith dick around with them vs. just buying the custom barrel from you.
Again, thanks for all the info, you've been lots of help!
