    The usps delivery was 2 days late, but nothing against b.kings. Received upper in great condition. Excellent packaging, bubble wrap and paper in box. Great product from a great company. Thank you.

    5/8″ groups at 100 yards while performing break in procedure. I am glad I picked this one. Blake was more than helpful as I originally purchased another and was allowed to change my order before it shipped! BKings sets a new standard. I am usually critical of anything without having hands on before purchase. No buyers remorse here! This upper hits the mark.

  3. Thomas S. (verified owner)

    The upper was even better than expected. I was looking for a very specific combination of upper, handguard, barrel kength and rifle twist rate and B King’s Firearms was the only place that had what I was looking for. The handguard and upper receiver fit was tight and the BA stainless steel fluted barrel is shooting tight sub-moa groups. Very pleased with this upper and the price was the best I found anywhere. Blake was very helpful and responsive, as well.

    Couldn’t be happier with this upper. It’s exactly what I was looking for. Delivered as promised. Count me in as a new B.King’s Firearms fan.

    This upper is very well made and is performing very well. Quality is perfect and I couldn’t be happier. Have put about 1000 rounds through it so far and it runs like a dream! If your on the fence do your self a favor and pull the trigger!!

  6. Austin (verified owner)

    Customer service was great! When I ordered the barrel I wanted was out of stock, so they willingly switched it out with another with no change in price.

    The upper got to me in good time and in good condition! I’m well pleased with the product and the service!

    This was exactly what I was looking for. It is well built. I would definitely purchase again. Thanks
