    KAK Magnum Bolt

    Posted by Charles on July 5, 2025

    As soon as you open the box and look at this piece you'll know its highest quality. Top tier. I haven't even used it yet but when you've been around awhile you know right away if you've bought the best or not. The laser etching and the slick shiny black nitride are the first clues. Clean smooth machine work are your second clue. I'm going to order a second one in case I ever need it. Right now I need the firing pin. This is a small hole HP bolt that needs the proprietary firing pin.

    Above and beyond

    So I built a 300 saum using this, I would definitely use kaks upper as well, I didn't and it was a project. But the bolt ran great. Also usps ripped the box and lost the part in transit and kak was great replaced the lost part at no cost, I would definitely do business here again

    You need a KAK firing pin to make it work

    Nice bolt, has a top notch gas ring, but requires one of their firing pin. I would have bought both if I knew.

    What you need for Magnum Performance

    Posted by Paul on January 1, 2021

    Machining is nice, headspaces correctly with .300WSM in my custom 26" barrel. Don't forget to order high pressure firing pin like I did (MY BAD). Also using to work up a Wildcat cartridge significantly more powerful than .450 Marlin for .458 Win Mag performance in the AR10 platform

    Excellent Magnum bolt for 450 Marlin

    I purchased because I needed a magnum grade bolt with space for the 450 Marlin, this one give excellent support.

    KAK Magnum Bolt

    I purchased this Bolt to go with my custom 300 Win Mag AR I built. Turns out this bolt performs very well! I paired it with a custom carrier and couldn’t be more happy. I wouldn’t hesitate to buy another.
