AR10/ AR15 buffer tube interchangeable?

[45C]

Hey,
I just received my AR308 buffer tube and it appears as if it’s commercial spec.

So I was wondering if I could use my milspec AR15 buffer tube as a substitute?

The brownells AR308 tube is about a 1/2 inch longer.

You need the shorter DPMS 308 carbine buffer and spring, then you are good to go.

The buffer that came with the AR308 buffer tube assembly is the shorter one , but the spring is longer than the spring in my AR15.
Here’s a pic.

Thanks, it worked perfectly
