I have a Plainfield M1 carbine. And my recent trip to the range the bolt broke. I have replaced just about everything in since I bought it. Can I just order another bolt from Sarco’s or someplace else. Does it have to be a special one since it came out of a Plainfield?

Nope. You chose well - Plainfield always used US Carbine dimensioned parts. As you've discovered, perhaps their heat treatment & selection of steel wasn't up to standard, but that bolt is what, at least 40 years old? I'd say you got your money's worth out of it. Just get a US carbine bolt, and check headspace if possible. ETA: Late Universal, and sadly current Inland & Auto Ordnance are not GI spec, meaning GI bolts do not always fit. |

You can use a USGI spec bolt BUT you'll need to have the head space checked, to be safe. https://www.fulton-armory.com/product/bolt-round-complete-fa-m1-m2-carbine/ |

| FLat if it originally came with one and you're worried about originality, round if you don't care and want a better [stronger] bolt. |
Liberals are a curious mix of communism and fascism, they want to destroy you but want to use your own money to do it.
