Is this buffer tube made from 7075 or 6061 aluminum?
Jonathan B on Jul 7, 2019
BEST ANSWER: Material: 7075-T6 Aluminum. In the item description.
How long is the tube and how many positions?
Carl V on Aug 5, 2019
BEST ANSWER: It’s standard length and 6 positions. It has a small lip up front that allows for smoother bolt to buffer transition
does this have stock position numbers on the top?
Hoss N Feffer on Jul 22, 2019

No, it does not.

Saves a little weight
Coming in at 3.0 oz, I purchased this to see if it was actually lighter than a standard buffer tube.
First impression is that it is a quality part and aesthetically pleasing. Second is that the buffer retaining pin notch in the tube is a little different.
It was a welcomed addition to my lightweight build and fits the bill when it comes to dollar per ounce of savings.
I'm glad I chose this tube over others since it allowed my budget to obtain more lightweight parts.
I'll definitely keep this one in mind for future lightweight builds.

Great product at a great price.
A step above mil-spec. Keeps bolt from banging on the end of the buffer tube. Will use again in my next build.
