    Excellent quality product really looks good on my rifle. I hope they are available again to buy another one

    This was my first purchase from B. King’s Firearms. I bought this upper and a dozen other pieces for an AR build. I was pleased with every item. These guys sell quality rifles, parts, and accessories. This complete upper was everything I was looking for and than some. The B. King’s barrels are TOP NOTCH! I waited until I had it broke in properly and put enough rounds downrange in different weather and target ideals. It ran flawless! Not only that, but the thing is a tack driver. The rifle shoots far better than I do, which is an awesome thing when you’re no slouch on the trigger. I just need to do my job and the hole corresponds on the target. If you’re on the fence between an item here or at another dealer, I’m telling you I wouldn’t go anywhere else if they have what suits me. Any questions I had concerning my order were answered that same day or promptly the next if they were closed. Can’t beat that.

    Price was very fair and in stock even when your competitors are out! Looks awesome but haven’t had the opportunity to use yet due to COVID and not wanting to go to the range right now. Thanks so much

    Handguard lined up perfectly, smooth to the touch for better, centered iron sight alignment. Love the FFSSR style, slim mloc where needed, rails where needed. The KAK looks great partially concealed under the guard and while it doesn’t conceal flash, in a pinch it won’t make you go deaf if you can’t get hearing protection on for a few shots. I need range time with it, but my other BKing upper runs flawlessly and I trust it more than my other platforms. I expect this one to be my “show and tell”.
