My father had this done in the 1950's.The bore is slightly oversize but we had good accuracy with the rifle and it was a good cast bullet shooter too.Ģ. You can set the barrel back a thread or two and ream it to. If you have a good one - and your gunsmith should be able to tell you.
The benefit here is the cheap surplus ammo, and it would be a real pussycat to shoot the full-size Arisaka with the 123gr 7.62x39 ammo. Obviously, more than a few threads' worth of barrel set-back needs to be done to accomodate the shorter round. The bullet diameter is proper for the Arisaka's bore, but the Arisaka's claw extractor would need to be bent inwards just a bit to get a better bite on the smaller diameter 7.62x39's rim. 311-.313" bore, she could have the original gun barrel set back and rechambered, to the Soviet 7.62x39 M-43 round. It might just be better to pay extra for the ammo and just shop around for "Deals" where possible.Īnother thought would be to check whether this is one of the "Good" Arisaka's or one of the "last ditch" or "substitute standard" models. Change the round and then what about the bolt and magazine, and so forth. As always, it won't be simple and a change in one area requires changes in others. Based on cartridge dimensions this is about the only route that won't require setting the barrel back so it can be chambered for a shorter cartridge. 303 British bullet which is the same diameter as the 7.7mm Arisaka (.311"-.312"). If you are going to "convert" it consider. How much are you planning on shooting it? It will take a lot of shooting to offset the cost of the 'rework'. I want a cheap shooter that looks as original as I can get it. I'm almost at the point of tracking down one of the chinese ones and then getting an original stock for it. Has anyone here had any experience with this? Seems like way too much effort and cost to get running. I don't reload, and I don't really want to get into it. I know 7.7 is about $28 a box of 20, but 7.62/.308 would be perfect cost and availability.
Type 99 arisaka barrel how to#
Though I still feel that the guys I talked to about doing it just either didn't care or didn't know how to help me out. I know the Chinese did it for a bunch of them after the war, and I know there would be some modifications that need to be done to the bolt and magazine.
I've called two different gun smiths that have both claimed it would take all kinds of work. They mention "setting the barrel back", "re-chambering" it, and yet never mentioning having to get a new barrel. I keep seeing posts on other forums that guys seem to have these Arisaka that shoot 7.62/.308 ammo.
