When designing our new Lightweight Enhanced (LE™) Castle Nut & End Plate System, we came up with two systems that virtually eliminate the risk of your castle nut ever backing out. With our two lockdown systems (K1 & K2), we’ve engineered a solution to install the castle nut onto the end plate that is not only robust but also stands true to our brand of innovation and ingenuity. The K1 system features a tapered castle nut that seals itself onto the endplate. This ultra-precision snug fit allows the castle nut to seat and seal itself into place without the need of staking the endplate. No ratcheting, no set screws, no backing out and no failures. All of these features at only .59 oz / 16.8 grams!

The Anderson Manufacturing MIL-SPEC AR15 castle nut is built from high quality steel and Manganese Phosphate coated. A Mil-Spec AR-15 castle nut might be an after-thought to most AR builders but it is an essential component for keeping your rifle running reliably. The castle nut simply slides over the receiver extension/buffer tube and is screwed on to secure the entire buffer and stock system to the lower receiver. This connection between the buffer system and receiver is generally regarded as one of the weak spots on the AR platform and this Mil-Spec castle nut will ensure your buffer tube is solidly attached for thousands of rounds. Especially if you stake the end plate resulting in a mechanical connection between the two pieces of metal and preventing the castle nut from loosening over time.
