noob question about buffer tubes
I have a m4 stock adapter. the adapter doesn't specify if it's for mil spec or commercial spec so how do I know which buffer tube to buy? are AR buffer tubes just generically the same?
I took the adapter to Cabela's and the guy tested it and the buffer tube on the AR fit on the adapter. so how do I go about choosing a buffer tube as above?

Milspec are a lot thinner and has a flat profile on the end cap while the commercial tunes are fatter in diameter and has angled end cap

when I read online, it seems that tube spec is only for the stock, not to go in the adapter. I'm just confused since the spec is for the thread length/diameter.

Just buy the stock that you want, it should be labeled commercial or milspec then you need to buy a corresponding tube, the thread pitch is universal on both, otherwise ar15 owners will pissed if it wasn't

The guy just said it was a standard tube. FYI after research, both commercial and mil spec tubes will fit in any M4 adapters or AR lowers. The comm/mil spec only applies to the stock-tube fit. Sent from my iPhone using Tapatalk

Both tubes are threaded the same and fit in the same receivers. Mil-Spec threading protrudes while commercial threading is cut out. Because of this, mil-spec tubes have a smaller diametre than commercial tubes, affecting stock fitment.
