I received one of these for Christmas to finish my pistol build. This baby is SWEET!!! Put everything together and headed for the range. I ran 100, 110, 125, 130, 150, 160, 165, and 230 gr bullets loaded from sub to super sonic. Not a single malfunction in over 300 rounds digested. Average 5 shot group sizes were around 2" at 100 yds. I believe I can tighten that with a little practice and adjusting my reloads. Bottom line..... this is an awesome upper and I'll be hunting with it next season. I highly recommend the 10.5" and 16" uppers in 300 Blackout which I now own both. My 16" upper has digested over 5000 rounds and runs like a top so I have high hopes for my 10.5" upper...

Purchased Monday afternoon, shipped hours later and received it on Thursday. Packaging was professional and well wrapped.
After receiving, I took it apart to inspect and clean. The finish on the rifle was excellent and everything was tight and within specs.
Took it out today and put 100 rounds thru it. No issues at all and more accurate than I was expecting a pistol upper to be.
I shopped online a LOT to look for a 300BO upper for my latest build and decided to give this one try. I am so happy I did. It was the lowest price I found and I can't imagine getting any better quality for another upper...
