| How do I tell if I have a milspec or commercial tube I want to put a better stock on and have to figure it out before I make a purchase |
|
The commercial buffer tube usually has a slanted end and the mil-spec are flat (90 degrees)
Also, the threads on a mil-spec are a larger diameter then the tube, so you will notice a step down from the threads to the rest of the tube and commercial tubes, the threads are the same diameter as the tube. Also, the commercial tubes are longer and heavier. |
