Worth the try - TRYBE Defense AR-15 Fully Assembled Upper Receiver Type II w/ Dust Cover & Forward Assist

I don't have the budget that I did a few years ago. I decided to try this assembled upper and I was not disappointed. The price was great and so was the fit. No binding, no trouble installing the barrel, bcg or charging handle. It worked great at the range where it counts. If you're not sure about buying one, just do it. After seeing how well this worked out I've ordered and installed a second one on another build. Good stuff. Nice to be able to still build again.
