Hey guys. I'm building a 10.5" upper M4. It's gonna be an sbr but I wanted to go ahead and build it. I have the lower complete. I bought a mil spec 6 pos buffer tube without a stock. Is it legal to use that buffer tube to build a 10.5" pistol?

You need a pistol tube. The 6 pos implies you mean to use it as a SBR. You might get away with it as long as you dont have the stock in your house but I wouldn't walk that line. Just buy the $15 pistol tube till you SBR it. Then you can sell it online when you're through with it.

Thats crazy. I have never priced one. I just ordered a regular tube yesterday from brownells and dealer cost for the tube, spring and buffer was $30. I only assumed it was around the same price for just the tube. I have one you can use if you need it. I need it back when you get your SBR approved. Just drop me PM with your info. I will just need $7 for shipping it to you. Let me know.
