Milspec ...I got stung / Lesson Learned

I am on top of this stuff...:icon_rolleyes::icon_rolleyes::icon_rolley es:

Bought a few milspec AR buffer tube kits and found out ...I did not ask and did not know there is a difference in lenght of tubes.

I thought Milspec meant you bought what the military uses.

Not so...there are 5 and 6 position tubes that are "Milspec" in diameter but
not so for lenght of tube.

Heads up for any new builders out there...use my lesson learned and avoid buying
the shorter tube.

I don't know what I don't know.......discovery learning is painful !!!

I don't know if you got stung but will what you bought work? Or perhaps you can sell what you have and buy what you really want.
