I need a new gas tube!

Can you post the S&W gas tube part number.
Thanks.

I bought the Armalite Carbine Gas tube as suggested here, and it is 1/4" longer then the stock gas tube. Is this what others here that are using it have? I mounted it and it seems like the bolt isn't hitting or rubbing it at all, but I want input from others. Thanks

Here's a picture of the length difference between stock M&P10 and Armalite Carbine tubes. Like I said when I tested sliding the bolt back and forth I can't feel or hear any rubbing or contact. Will this gas tube work? Thanks

So the gun cycled just fine with the Armalite tube.
