Default Is this M1 bayonet defective?

Today I received the Utica Cutlery M1 bayonet I had ordered from CMP. After spending much time cleaning all the cosmoline from every nook and cranny I tried it on my M1. It won't go all the way on and latch on the lug. After looking at various parts and pondering what was going on I realized the muzzle ring is not concentric, which isn't allowing it to slide over the small portion of the gas cylinder lock at the muzzle.

I got out my calipers and took measurements of the inside diameter from various angles, or positions. If you think of the ring as a clock face these are the measurements:

12:00 to 6:00 - 0.615"
9:00 to 3:00 - 0.639"
10:30 to 4:30 - 0.634"
7:30 to 1:30 - 0.619"




I think you can see in the one photo that the muzzle ring looks to be not concentric. Any thoughts or suggestions?

From the looks of your bayonet, Id say it has been installed on at least one Garand. Are you saying that it will not let the latch engage the stud? If so take a few cuts with a file on the latch and custom fit it. I had to do that with one of mine.

The bayonet won't go back far enough for the latch to engage the stud, by a great amount. I thought the latch was the problem, but then I found the muzzle ring will not go over the muzzle and gas lock properly. It gets stuck at the front of the gas lock.

I had the exact same issue with mounting a UC bayonet on my Smith Corona 03A3. I simply swaged the interior of the ring with a tapered steel plumb bob to both widen and make the ring concentric again....worked perfectly (see link below for more info).

Thanks for the info coolhandluke, I'll see if I can get a plumb bob today and try to get the inside of the ring round. There must have been some rough handling of these bayonets to get the rings out of round like they are.

Soldiers aren't exactly known for gingerly handling their gear. I can see the ring getting deformed by being mounted on a rifle and then falling/dropped on the floor.

Today I got around to using a plumb bob on the muzzle ring and now the bayonet fits the M1. It fits nice and tight with no rattling or slop.
