greenr18, enjoy that Arisaka. Ammo isn't the problem it once was, PPU and others are making new, reloadable ammo. Series 6 is a fairly late one. It may not be as well finished as an earlier gun, but all arisaka's, including the "last ditch" rifles had to pass proof. The latter guns should more properly referred to as "substitute standard" The Japanese made every attempt to lower costs and speed up production with these guns. One of the first things to go was the chrome lined barrel. The steel buttplate soon followed, along with the cleaning rod, the wire monopod, and the aircraft sights, in an attempt to save steel for other things.
Arisakas may not be the prettiest milsurp out there but they are one of the very best at fulfilling their intended purpose. They are nearly indestructible. The Japanese were the first to realize that a chrome lined bore in a rifle using corossive ammo, was an enormous advantage in a humid, tropical environment. The sliding bolt cover was perfect for keeping dirt out of the action, and a smart soldier knew that a judicious whack with a hammer, in the right places, would keep it from rattling. That odd, in front of the receiver peep sight is easily adapted to, and quick to use. I have started many a fight with these words, but I will continue to say them:
I will take a good, early model 99 Arisaka into battle over ANY Mauser, 98 or otherwise.
Good shooting!
