    BCG

    Posted by Eric on June 18, 2026

    KAK customer service is top notch. Had an issue with my upper where the BCG got jammed because the upper barrel clocking was incorrect. Sent the upper to KAK, they diagnosed the issue and got me up and running again. Test fired and all. Sent me videos of the issue and did a great job getting back quickly. Thanks Cody!

    308 & 6.5 creedmoor

    Posted by clinton arnett on October 26, 2024

    i have both built 308 and 6.5 creedmoor but bot would jam. I tried changing buffer, spring and added an adjustable gas block but still would shoot and hang. I decided to try thhis kak double ejector bcg, i have put the one i bought in both guns, set gas block. once i got the gas block set, both fired without a jam. i put 120 rounds thru both of those guns. i had no jamming problems. i will be buying another one so i can have both guns ready to go instead of swapping the bcg back and forth. i would highly recommend this.

    This BCG does exactly what it says it does in the description! It was purchased as a replacement and was a replacement for a different manufacturers BCG that didn't perform.

    Another quality part from KAK. Customer had built himself an AR-10 and was having all kinds of issues. After some diag. we replaced the cheap bcg he had with a quality one from KAK and all issues were resolved.

    Quality For a good price

    Posted by Everett Hames on June 26, 2023

    Large frame bolt carrier groups can go from inexpensive to very costly and a lot more than I was willing to pay. KAK's double ejector BCG offers quality that is as good or better than competitors who charge a lot more. I see quality at a good price from a company that knows how to manufacture. Only thing I have changed is to put on a Rubber City adjustable gas key to make shooting suppressed more pleasurable.
