I was looking at the ebay online gun show segment when I stumbled across this:
Rifle conversion kit - shoot 7.62x39mm in a .30-06  No real explanation of how this thing works, or whether you'd be able to use it on a Garand. |

Looking around, they've got all kinds of weird adapters like this, shooting 22lr through a .308, .38 through a 20 gauge shotgun.... How does this work?

They are not very safe. There is always a chance that the adapter can come out while the empty case is being ejected. I would stay away from such devices.

In addition to the problem related above, there is also the issue of whether or not the port pressure curve is within GI spec. If the gas port pressure is not within a fairly narrow range, damage to the rifle and maybe yourself could result.
Absent independant certification of same, I would not think of using this device in a Garand. Bolt rifle, maybe. I don't think the economy benefits would offset the necessity, hassle, and ammo expenditure entailed in re-setting the sights when switching from one to the other. YMMV. |

Isn't 7.62X39 a .311 caliber?

I would not attempt in a semi auto, A single shot or bolt gun? May be?.

This is nothing more than a take off on what the US govt. tried to do back in the 60's when converting to the 7.62X51 round. It did not work then and it won't work now, safely. There is soooo much more than to just popping it in and adding some loctite to it. You also end up with a very loooong throat (freebore). What usually happens is it comes out when you do not want it to and it stays in when you want it out. If you were to fire a 7.62X39 round with the adaptor out, it results in way excessive headspace. I know someone who did it with a .308 and the case comes out looking like a .45-70.
Caveat Emptor!!!! |
