Utg = quality - UTG Pro AR15 6-position Commercial-spec Receiver Extension Tube

I have a handful of UTG products utilized on my AR's; two uktra slim handguards, a great target grip, and two of these extension tubes.
I was putting together a plain jane, mil-spec, carbine lower and had an old CAR buttstock i wanted to use. Im pretty sure it's supposed to be a mil-spec stock, but i mic'ed it and it measured closer to a commercial size. I didnt want excessive looseness or rattling, so i ordered this UTG commercial tube. Apparently these commercial tubes are becoming a thing of the past because this UTG one is literally the only manufacturer i could find on the internet.
The CAR stock fits great, the extension tube looks and functions great. It says "made in the USA" on the end.
