The front of the carrier key on my no-name 9mm bolt is bent. The nose lifted like an eighth from the carrier, although the screws were surprisingly still torqued and unbroken. Can anyone here recommend me a source of new keys?

Haven't seen those for sale anywhere. You might be looking at a new carrier unless you can convince a 9mm carrier manufacturer to sell you a "gas" key.
What caused the key to bend? When is it under load in a blowback design?
That’s exactly the question that needs to be addressed before replacing the key. There’s no gas tube and no cam pin, so what bent the key? The only thing the key should touch is the charging handle unless it’s striking the receiver extension during recoil. How is the charging handle? Does the receiver extension (buffer tube) show signs of repeated impact? Which way is the key bent? Pictures?Quote:

The only thing it could possibly be hitting is the front of the charging handle, which doesn’t really look like its been getting hammered. Perhaps it is just made of garbage steel, since it was on an unidentifiable bolt. Maybe it bent while getting mortared. Dunno. Its been in that gun for many thousands of rounds, so I’d be happy to just replace it.
You cannot use or modify an standard gas key?
I was thinking about trying to do exactly that. I have a used one laying around, and it looks like it might work.Quote:

Try contacting foxtrot Mike. They just have them for sale
