Before I move this to another online forum, I thought I'd start with the folks right here at NWFA. I picked up a Type 99 Arisaka on the cheap recently and had a few questions I'd like to ask for those that have experience with them. From what I can tell from the markings, it was produced in early 1944 at the Toyo Kogyo arsenal. Like many of these rifles, changes were made after it arrived here. The mum is still there, but is partially destroyed by someone who decided to drill/tap the receiver sometime in the past. The bolt has been jeweled and looks really nice. A Williams peep sight was added. And, like many, it was re-chambered to .30-06 with a new barrel and front sight. The original stock was cut down to make it more of a junior size rifle. The rifled action of the gun seems to be in great working order, tight, smooth operation, good trigger. I'm going to replace the stock with either a traditional type 99 stock or maybe something newer like the version Boyd's sells. The finish is pretty beat up. I'm considering giving it a Duracoat finish using their DuraBlue product. I didn't put a lot into this gun, so I don't mind doing some of these mods since it's hardly the stock gun it once was. So, what I've been able to find online, there may be issues with the re-chambering of these guns to .30-06. What I've found online would indicate that if the barrel is marked US .30 Cal, the re-chamber was done here. If it's marked 30-06 (which this is), it was possible re-chambered over seas, even by the Japanese themselves. I've understood the US ones would be better. Have any of you had any experience with a re-chambered type 99? What are your thoughts? I'll likely have it checked by a gunsmith, but I'm just curious. Thanks!
