How can I tell what kind of tube I have? I have a feeling this is a dumb question, but as of now I don't have an answer.

I have seen different aftermarket buttstocks that have a disclaimer such as: "Will only work on Mil-spec tubes," or " a drop-in replacement butt-stock for carbines using commercial receiver extension tubes"
How can I tell what kind of tube I have? I have a feeling this is a dumb question, but as of now I don't have an answer.

Thank you. Another dumb question. Can I put either size tube on my receiver? As far as I know all lowers are the same, right? It's just a matter of the OD of the tube, not the receiver.

Yes, either tube will go on any lower.

I am probably stating the obvious, but even though either tube will work on any lower know that if you get a milspec stock it will not go on a commercial spec tube.....

A friend of mine told me "Your work has really made you cynical" my reply was "Cynical.....I passed cynical five years ago....I now live in reality"
Considering the amount of fancy equipment now seen in competition, some readers have complained loudly that the 'average guy' does not have a chance. It might be pointed out that this average guy never has had a chance. Competition is held to determine what is best, not what is average. And if all the equipment were standardized, the man who won would still not be in any sense average.

Go milspec. I just swapped mine out and the Milpsec tubes have much less rattle on the stock. Also, if you go to the Magpul website they have a web link that describes how to tell which one you have. Some commercial tubes are slanted at the end. Milspec ones are flush flat.
Here is the link: Hope it is ok to post
