What size gas tube does this have? Is the lowwer and upper mil spec

It has a "Pistol Length" Gas System and has a Mil-Spec Upper & Lower.

Philip, this has a "Pistol Length" Gas System (.750) and has a Mil-Spec Upper & Lower. https://diamondbackfirearms.com/portfolio/db15cckm300fde/

Does this rifle have a mil spec tube?

John, the model I received came with a "Commercial" Buffer Tube. You can verify this with Diamondback Firearms at toll-free: (877) 997-6774

I guess this model they call it a commercial tube rather than a buffer tube. I'm glad I was able to assist you. Thank you good day.

they have "commercial " buffer tubes

Great rifle for the price I purchased it at! I must say I highly recommend diamondback firearms to anyone looking for a good rifle at a good price!

So far I'm really enjoying this rifle. For $550 this is going to be hard to beat. This is my first AR, and I'm very happy. The gun feels solid; no cheap feeling at all to the gun itself. The butt stock is actually really nice, comfortable, and locks into place well. It even comes with some KM to Picatinny attachments, which I did not know. Huge plus. The only negatives I see right now are little, easily fixable ones. The trigger is your average mil-spec and absolutely needs a polishing to be smooth. The magazine it comes with is a cheap, metal, surplus mag. The pistol grip isn't the most comfortable. I only have 100 rounds through the gun and I can already tell it's going to be a pain to keep clean. This is probably one of the best "factory" AR's you can get for around this price.

Great gun for the price I have no complaints gun works and shoots great. This was first time ordering a gun from here and would definitely order another one. Placed order around 11:00 am on Tuesday and was picking my gun up at local dealer the next day. Very pleased with my purchase from here and fast shipment.

This is my first Diamondback rifle and I am pleased with this purchase. The FDE coating is flawless and over all looks awesome. I have fired 200 rounds out of it so far with no issues. I will definitely purchase another Diamondback in the future.
