Colt M-4 buffer tube

[JSandi]

Looking at a Colt M4, 6920 possibly.

I have a Magpul CTR Stock on my SIG556, Commercial tube. Will it fit on a Colt M4?

I see where the Colt M-4 buffer tube is 0.02” smaller in diameter than other AR-15 buffer tubes.

This means it's a Mil-Spec tube, right?

Would need to buy the Mil-Spec Magpul stock...

yes,
a milspec tube requires a milspec stock body

You have a commercial CTR on your SIG. You will need to buy a Mil-Spec CTR in order for it to fit on your Colt.
