    I have a s&w m&p ar-15 with a 16 inch barrel. I want to change the barrel to a model 1 24 inch bull barrel. One of the problems is the gas tube. Do they make a gas tube tube that is long enough for 24 inch barrel and will fit my m&p 15. Also will the factory bolt work with this barrel.

    It prolly uses a rifle length tube. There are 3 main gas tube lengths: rifle mid and carbine. Best thing is to get a new bolt with a new barrel. The old bolt carrier will work.

    You'll also need a new gas block for the bull barrel.
