Sure, he can get whatever he needs for a Savage conversion. I'd suggest Kevin Rayhill (Stockade Varmint Rifles & Stocks) 308-432-5114 for the bolt head and maybe the barrel. But then you can get pre chambered barrels from several barrel makers, Shilen, Pac-Npr and Lothar Walther to name a few. As for the magazine, I'd think you could get one from Brownells, but if you call Kevin, he probably has a boxful somewhere. BTW- the boltface swap takes about 5 minutes. The barrel, maybe 10.
