Identifying USGI stock?

not a Keystone...likely miltonbradly... nice stock..make sure you tap the threads or youll be sorry..

What do you mean by that? Sorry if that's a noob question but this is my first M1903A3 and I've never had to tap any other stock I've had.

The owner of Northridge comes from Belgium or France, I know him from several gun shows in Europe. Have one of their C-Stocks aswell, they have absolutely astonishing grain and are of high quality. They are all NOS.

the holes for the buttplate and lower swivel arent tapped for screws...if you force a screw into the hole...you may,,crack the stock, stick a screw in the hole, or destroy a screw...
as well as you will need to drill the hole for the bayonet lug at the nose...
stock may also be missing the rear guard bushing...dont shoot the rifle without that itemsinstalled. you will destroy the stock.
new unissued stocks came this way from Milton Bradly

Got'cha. Wouldn't happen to know the size taps I would need off the top of your head, would you? Also, the stock came with the cross bolts and rear guard bushing installed. They're just really rusty and hard to see.

rusty is ok..just brush them out..
no, i dont know the pitch, i made my own tap set...Brownells used to sell the small one,..but have yet to see the big available...so i made my own...
