Heavy duty - Spikes Tactical Pistol Buffer Tube w/ Step and QD Socket

I bought this extended AR pistol buffer tube in case there was some sort of ban on braces that have a buffer tube that accepts a stock and having the extra length would be beneficial for other purposes. I also really liked the QD attachment on the end figuring I might be able to do something with that, but I couldn't get any of the QD swivels I have to work including Troy, Magpul, and a cheap unknown manufacturer. Other than that the quality is topnotch with great threads, weight, and finish. Would have been 5 stars of it came with a QD Sling that works.
