The quality isn’t what i’ve come to expect from aero... - Aero Precision Enhanced Carbine Buffer Tube

I purchased a lot of Aero products and the quality of this buffer tube isn’t what I’ve come to expect from the company. First if you look closely at the machining you see imperfections all over the tube. Second and this is the biggest one my fab defense stocks adjustment spring loaded detent isn’t able to seed all the way down properly in the tubes guide holes. My fab defense stocks adjustment button is loose and floppy because of this, i’ve tried it on several other tubes I own and I don’t have that problem. Last thing there is a problem is when I tried to screw the tube into the lower receiver, I couldn’t get that last revolution to make the buffer detent seed all the way back between the enhanced tubes notches. When I did twist the tube so the detent was at the absolute back of the anti-rotation notch my upper receiver wouldn’t close... none of these problems happened on the dark defense buffer tube though that tube did have its own problems, mainly the anodizing being shiny and rattle because of the circumference of the tube. So basically either this tube is completely mill spec and all my other parts are not or this tube is not mil-spec...
