The easiest and cheapest way to acquire one is to look for a cheap bubba. I recently picked up one that someone decided needed a scope and also didn't like the top wood or band. The fore end was cut off where the front band fits. The D&T was a disaster and looked like it had been done with a hand held drill. Then it was painted camouflage colors and eventually the mag was misplaced. The rear sight was a stamped Mark 2 which is the first one I have seen. The bore on this rifle was a disaster. Uncleaned after corrosive ammo use.
I picked up the whole mess for $60 and that was about a month ago. Since then I have seen two more in similar condition but the flash hiders had been bubbaed beyond repair.
