Perfect fitment and design - Timber Creek AR Mil-Spec Buffer Tube

I installed this in a 300 BO build on a AR platform. It fits perfectly and even has the nice little notch in the threads to cup around the buffer spring rentention pin. It completes its job in retaining the buffer pin, but the notch allow for another thread or two of twist inside the lower receiver. I bought a minimalist stock and it fit great; it functions as a standard DOD M4. There’s actually less “wiggle” in the stock, so I’d say it fits better than the weapons I was issued.
