    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.

    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.
