AR buffer tube castle nut question

[ShooterMcGavin]

Do the buffer tube castle nuts on an AR-15 use a wrench which can also be used on the buffer tube castle nut on an AR-10?

In most cases it should but the AR10 doesn't use AR15 standards. They vary widely.

I've never encountered an AR10 that didn't use AR15 buffer tubes; my Armalites and DPMSs certainly do.

Great. Thanks.
