Thanks for the link that is the exact one I purchased!!

Please disregard I have found out what the problem is. From measuring my rifle and looking at the carbine length Armalite gas tubes I believe this is what I need. It measures 12.0625 so slightly longer than my Aero mid length gas tube. The "Carbine" in the description had me skipping over that at the Armalite site and once I went back and investigated the length I discovered its actually longer than the mid length DPMS gas tube. Funny how I have everything stating it is DPMS compatible (Barrel, gas block, receiver) and I need an Armalite gas tube.

Starting my first DPMS 308 build and have a concern on gas tube length. Barrel is a Faxom 16" gunner profile mid length gas Upper is an Aero M5 Gas block is Odin works adjustable low profile. I bought an Aero gas tube in mid length which states it is good for and "AR10" on their website but when I install it, It looks short to me based on what I have read here. The tube measures 11.75 I have found some information out there stating mid length gas tube should be 12.5 but that seems like it would be to long? I have also read that the Armalite AR10 gas tubes are longer but I do not see a mid length on their site. Little bit confused hoping someone with more knowledge than I can help shed some light on this
