    Bcg was well packed and a piece of art work machine work was wondering it looked really nice no doubt that it will perform the same

    KAK magnum bolt carrier group

    Posted by Ray on August 16, 2024

    I used this bolt carrier group to build a 338 RCM. Works great, in 18" AR 10, chambered in 338 RCM, 1/2" accuracy with a variety of hunting style bullets. Brass is made from 6.5 PRC cases.

    This is a well made BCG

    Posted by George Williamson on January 1, 2024

    I am building a 300 WSM gas gun. I haven't received the barrel yet. But this BCG is built for this and has double ejectors. It goes with the modified upper I purchased. It appears to be very well made and I am very sure it will work. The bolt face measures as advertised. I can't wait until I put this together. Hopefully I can update this review when I do.

    KAK Magnum Bolt Carrier

    Posted by Aaron Parker on August 30, 2023

    I bought this for an unfinished build. I haven't had a chance to use it yet, but it is definitely well built. This is for a 6.5 PRC, but I'm thinking about building a .300 WSM too and will need another Magnum bolt for that. I'll definitely be getting it from KAK Industries, along with a few other parts.

    Everything appears good so far as I haven't used it yet. I'm awaiting my 6.5prc barrel along with other components to complete it.

    Works well on 300 wsm

    Posted by Franz on December 26, 2017

    I built a 300 wsm ar10 and modified a standard bolt but was having feeding issues. Realized I needed to remove even more material from the extractor and that the extractor groove in the bolt would leave a larger gap then I felt comfortable with. Was looking to see if anyone had worked there way around this problem when I found these bcg's. This bcg solved all the problems and worked immediately! The bolt is made specifically for the magnumbolt face and the extractor and extractor groove are sized appropriately.
