Commercial.

ETA: I stand corrected. The current offerings must be mil-spec according to a few of the later posts. The one I had a few years ago had a commercial tube though.

You will be very happy with your new rifle. I have had several Armalites and they have all been great!

The ArmaLite buffer tube is MilSpec and NOT commercial.

The best way is to measure the diameter of the buffer tube. Mil-spec is 1.148" and the commercial tube is 1.168". There is some websites I've found that claim the mil-spec tube has a flat end while the commercial tube is slanted. Also the mil-spec tube diameter is slightly undersized from the thread diameter while the commercial is the same diameter as the threads.

Measure the diameter with some calipers and verify.

ETA: Just found a link to AR-15 Volume II book explaining the differences

I, too, just acquired a Armalite M-15A4 (flattop M4)............

Haven't shot it yet, but am very impressed with the fit and finish.......my son is about to have a cow to shoot it!
