So, after too much mucking around with the borrowed tools (receiver wrench and barrel blocks) in my uncles backyard, we managed to install the .308 barrel, and the Frankengarand was given life (without the screaming melodramatics, a hunchback or even angry villagers – although undoubtedly the neighbors were somehwat concerned).
For those just tuning in the rifle is a mutt, built up on a Breda receiver and using a parts from almost every manufacturer in the Garand world, the only requirement for these parts was that they function, and that the finish be less than optimal (I didn’t want to refinish any good condition parts that might be of use to those rebuilding their own garands).
(Edit 18 June, 05: Publicola correctly pointed out the receiver is not the youngest part of the rifle, in fact it’s not the oldest either as the oprod appears to be WWII era. I guess for accuracy we’ll call the rifle 7 days old at this point instead of mathematically picking the mean age of the parts, and going from there.)
The receiver is 50 years old, the other assorted parts range in age from WWII to Korean War vintage, with some modern manufacture bits added (primarily the stock and muzzle brake).
