Gas key commonality?

[Czgunner]

I did a few searches and couldn't come up with anything.

Is the LR308/DPMS pattern BCG gas key the same as the AR-15 BCG gas key?

For the gas-operated guns, they're all the same.  Minus Armalite AR-10 gas keys.  We've posted on those before in a thread here. 

Piston gun are a different animal, and dependent on the manufacturer.

Thanks. I've got a bag of gas keys as spares for my AR-15's and wanted to know if they fit my Stag 10.

They should.  Post a pic of the gas key on the BCG of your Stag, with one of those AR15 gas keys right in front of it.   That will answer the question right away.

Without a Mik they look exactly the same. PSA Nic bor and Toolcraft Nitrate.

Thanks. Even though they looked similar in person, I was concerned about a spec that I didn't notice.
