I ordered a new 1-7 6 groove 5R barrel from Crown Ridge barrel works. I also ordered a new larger bolt head for 224v. The new barrel took just over a week to arrive. The bolt head and headspace gauges I think came from Midway.
The re-assembly was actually easier than expected and I had the barreled action ready to go in an evening. while the barreled action was out I also tuned the trigger to just over 2 Lbs.
I was again shocked at how easy the trigger was to tune and how good it turned out.
