    Best castle nut setup in the business

    Perfect for the builder who doesn’t want to mess with staking. Saves me time on the overall build while also being easy to disassemble if that was ever needed. I don’t usually use the qd sling attachment point, but I like that it’s there just in case. I’ve got one on every ar I’ve ever built and I intend to keep installing them for every future build as well.

    Awesome product awesome service

    I ordered this thinking it might be delayed given the current state of gun parts. Nope it arrived quicker than most of what I ordered. Way to go Botaxh. Also, love the product. Third build I've done and the second time I've used this. It's not that much more expensive and its a time and headache saver
