    Outstanding product and service from B. King’s Firearms! The price is great for the quality of the product and the speed in which it was shipped. I will definitely buy from B.K.F. again!

  2. Anonymous (verified owner)

    Fast shipping and a great product. 2nd upper from them and it wont be the last

  3. Joseph P. (verified owner)

    Well assembled and STOUT! Shoots very consistent and seems to like the heavier stuff >150 grain. Very pleased will this build!

  4. Christopher Smith (verified owner)

    I am unable to fully rate the upper that I received, since the build is ongoing. But I can say what I have received appears to be everything that I was expecting. I have been looking for a .300 Blackout for several months now, but none appear to give the size limitations and features that I wanted that B. King provided at a very reasonable cost. I do thank you and and I guess the right response would be Semper Fi for such dedication!

    Great upper with fast shipping. Thanks Bkings!

  6. Jon C. (verified owner)

    One bolt I had wouldn’t align with the barrel extension. The same bolt works in 2 other ARs. There was paint scrapped off where the gas block looks like it was pinned. Not a big deal, but a touch of cover up paint would be nice. Functions great and was fun to shoot. Accurate.
