The Ratchet Lock Castle Nut End Plate set works with mil-spec OR commercial buffer tubes and eliminates the need for staking. A quick upgrade to any rifle build, the Ratchet Lock Castle Nut End Plate features a QD mount and easy installation with any buffer tube.


The patent pending Ratchet-Lock Design eliminates the need for staking the castle nut and gives a rock solid lock up while being able to remove it easily if needed in the future.


The central QD sling swivel mount allows for neutral positioning of your firearm with multiple sling configurations.

    Best castle nut setup in the business

    Posted by Theo M. on 31st Jan 2022

    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.

    Posted by R. L. on 1st Sep 2020

    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
