jmurman,
Fulton Armory is in MD somewhere..... do a google..... but they are pricey and generally backed up for a time.
Send it to Clayton Smith @ West Texas Armory, Dean Dilabaugh @ DGR, or Ronnie Morris @ Match Service Works. All these guys have great reps for good work. I can personally vouch for Clayton and Ronnie. Both have installed .308 barrels and refinished an M1 for me.
Best regards,
Swampy
Garands forever
