now imagine he was carrying something modern like a blaser r93 professional, would probably have used half as many barrels hitting twice as much stuff along with very high wearing barrel material (high vanadium etc. i think, would have to go look that part up about the barrel make up again) and likely no extra stocks
so its going to take probably 100 yrs and a 2nd generation of use to be able to tell the full story of some of the more modern stuff available today....that being said...for something made pre-64...thats pretty darn impressive quality
