I have 2 complete 1903A3 rifles and the receiver plus various bits and pieces for another. A3 #1 was a bring back from WWII, so I was told, except the safety assembly has been replaced with an aftermarket BS unit. I have the parts to fix that. Some moron drilled & tapped it for a scope, it has a straight grip stock and the receiver markings are not offset so I don't think it's a real 03A4. The other rifle and the receiver are unmarked. My question is do I mess anything up more than it already is to take the already D&T action out of the stock, put it in a pistol grip one and make a A4 clone out of it then move the action to the empty stock and build up a rifle by adding parts? If 03s are like AR's I'm in trouble as I have a total of 3 uncommitted bolts assemblies that seem to demand complete rifles of which to be a part. I'm also open to the possibility of using some of the parts to build a hunting rifle of some as yet unspecified caliber.
