[ARCHIVED THREAD] - Gas Tube

Posted: 3/17/2011 8:49:06 AM EDT

I need a lttle help with gas tubes.

I just got a DD 16" mid-length barrel and I am trying to figure out what length gas tube I need for it.
I have seen the tubes listed as car,mid,rifle,short,medium,long and in inch sizes.
This is my first time building one and just need one of you fine people to help me out.

Thanks.
