    I’ ve purchased upper from BKing before for AR builds and have found everyone to be high quality, accurate and reasonably priced. My go to upper. In addition, their customer service is great! Thank you.

  5. Charles P. (verified owner) –

    Very nice , accurate , quality upper. Shot 250 rounds in one afteroon, heated up and functioned well. Would but again and recommend! Really like the style and functionality of the handguard.

  14. Christopher (verified owner) –

    Good quality. Good communication.

  15. Robert Powers (verified owner) –

    Pardon the pun, but great bang for the buck. I also ordered the extended A2 flash hider & had it pinned & welded to make it a legal rifle. Beautiful work and it came in a reasonable time frame considering the pandemic & everything being sold out. The weld is neat, and they didn’t grind it off so it’s still obvious that it’s been welded, just in case someone checks. The hand guard is functional for a good grip and mounting everything you need, and looks very cool too.

  16. Francis G. (verified owner) –

    Outstanding product and service!!! Thanks for making it easier for me to stay in the fight!
    God bless you brother and God bless the USA!!!!

  17. Robert P. (verified owner) –

    This is the 2nd complete upper receiver I’ve purchased. Considering the environment & that they pinned & welded the muzzle device, the 3 weeks from order to my door was very reasonable. It’s a beautiful piece & the weld is perfect. Neat, but they didn’t grind it off. Good service and communication too. Great value.

  18. Richard Wilson (verified owner) –

    Solid, quality, and looks great

  19. Anonymous (verified owner) –

    First of all very quick ship. Quality components and workmanship. A very sturdy upper receiver assembly. Matched up well with Aero lower and very compatible with other brand BCG and charging handle. Zeroed at 50 yards and got better groups than expected for 14.5″ barrel. Bottom line extremely pleased with product, especially at this price.

  20. Adam Cook (verified owner) –

    Seeing that I’m just over 2 hours north in Michigan shipping was incredible. I got the notice it shipped Monday before noon and got it Tuesday at 4. Once I opened it I was extremely pleased with the quality and appearance, looks so much better in person. The hand guard is just too perfect and it just works perfectly. At the range I had no issues whatsoever and great accuracy also. I was considering some of the high end AR stuff, not anymore. This is my go to place for my next build.

  21. Anonymous (verified owner) –

    Perfect absolutely perfect.

  22. Johnny T. (verified owner) –

    I took a chance on a company thar I’ve never heard from before, and am glad I did!
    The upper was exactly what I was looking for and the customer service and shipping time was far better than I expected
    B. King’s, without a doubt, will be a regular vendor for me now.

  23. Josef Anthony (verified owner) –

    Great complete upper. Enough rail and slot space for any and all accessories. Though it’s a little heavier than I expected, but solidly built. Mated with my Aero Precision lower w/o issue.

  24. Mark Steiner (verified owner) –

    Overall the upper appears to be good quality. Came with a few blems on the receiver and the muzzle device wasn’t pinned / welded perfectly straight but I can live with it.

  25. Dione (verified owner) –

    Nice upper! Well built

  26. John Anthony (verified owner) –

  27. Aldous Benjamin Z. (verified owner) –

    All i can say is that these guys know exactly what they’re doing! Very well made upper and extremely fast delivery time! First time ever buying from B.King and i was a little skeptical on how the product would turn out, but I decided to put my trust on these guys and to my expectations, they’ve met every criteria i looked for. Im going to be purchasing more from these guys and would 100% recommend to other folks! Wonderful work fellas.
