    Looks great, feels light, and the Parallax Tactical rail sits wonderfully in the hand. I have yet to test fire, but I’m excited.

    Processing was fast, shipping was fast, and I received exactly what I ordered.

    My favorite upper. just buy it. i was hesitant waiting for it. as soon as i massaged it in my hands it felt as though i was cradling a masterpiece. i bought a blankie and pillow for it so it can sleep next to me. my wife can sleep on the floor. Also, im not a doctor but im pretty sure this upper can cure aids AND cancer. Also, here is a short NAM write up i will submit for approval……

    Excellent product , excellent quality , excellent customer service all the while that sickness running around , Excellent price for all that your getting, Can’t be beat , if your considering B King just go for it , you won’t find better anywhere else on the market, don’t believe me … do your research, you’ll see the bottom line, example this product here has a melanite treated gas tube … and they seam to put them in a lot of there uppers , something as small as that does make a pretty significant difference, less friction , less heat , lengthens duty life, like the actual act of firing… yeah your firearm can have components that make it damn near indestructible (You gotta be really determined) already in it when you get it , and if you know a little about metal work, machine work, or these machines that make our guns you know why Blake Is King. Grateful to own such a quality piece.

    Good quality upper, fair price and quick shipping. Thanks!

    This thing is awesome! I bought this upper back in January for $275, I was a bit skeptical, but this upper has completely surpassed my expectations. I’m a BCM guy, still love them, but I’ve never tried the 12.5, I bought this to see if it would be worth it to get the BCM. Well, 2K rounds later and a course behind it, I’m not getting the BCM, I’ll probably get another 12.5 or 11.5 from BKF for my wife. Paired with the Surefire Warcomp, and there is almost no recoil. I’ve fired hundreds of thousands of rounds through M-16/AR15s and this thing has been my absolute favorite. Love the FFSSR Handguard with a magpul AFG And Cloud Defensive LCS for the Streamlight. Even for $120 more than I paid at the first of the year, I gladly buy this again, it’s that awesome. I’ll run this thing against my BCMs any day. Just wish I could add a photo. Don’t think about it, just buy it!

    I’ve not been able to function test the upper yet. But pleased with visual inspection. Installation and fit of 3rd party parts; sights, fore grip, light mount, has been excellent.

    Awesome

    I have purchased about 4 or 5 uppers from BKings. Quality parts, pinned gas blocks, function great, handles and feels amazing in the hands. No issues. Would highly recommend.

  17. Graham (verified owner)

    Building my first AR. I was having difficulty finding parts, B.K. had everything I needed and the shipping was quick and has extremely reasonable prices. The upper seems to be very high quality. This is my go to place for AR parts. I will definitely be back to but more parts/upgrades. I’m also going to recommend B.K. to friends.

    Wow, where to start… I’ve been looking for another upper for awhile now..now across this seen the reviews and specs…figured I’d take a chance. Three days! And it was in my hands ,I got a fire forward grips and after I felt how it cradled in my hand..wow .not putting a grip on it..it just feels amazing exactly as it is! The look of it is amazing the finish flat black…but not chalky like some..I put the lighting and off and sight no marks..very strong no glare finish !
    This is my new favorite upper just can’t say enough about it..just feels amazing and love the 4 qd mounting points …if your having any doubts….get it! You’ll be glad you did and have it fast !!!
    I also got the C148 bcg and sledgehammer ambi charging handle with it..wow..I’ll do a separate review on them.. but this is for sure my new favorite site 😁
