In all honesty, I'll probably want a match barrel in the end.. but might as well experiment with the cheap option before destroying the expensive one. Match barrels are starting at 200, then threading, locking block. You're talking a 300 dollar barrel before all is said and done. If I need a threading that isn't normal.. I'm running a larger financial risk doing it to a match barrel, especially if my idea is untested. The stock barrel I'm getting for 80 includes a locking block, with threading (first try.. may have to redesign) it'll be in the neighborhood of 150, with custom thread protector.. probably in the neighborhood of 225. I'm still up on the match barrel price wise, and will have two reusable parts when I'm done, and a verified or disproven solution.
