Fortis LE Lightweight Enhanced AR-15 End Plate System – K2 – Castle Nut
When designing our new Lightweight Enhanced (LE™) Castle Nut & End Plate System, we came up with two systems that virtually eliminates 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 K2 system utilizes a locking lever design that seats itself through a designed slot on the bottom of the end plate and into corresponding cutouts on the castle nut. This ultra precision fit allows the castle nut to seat itself into place without the need of staking the end plate. No set screws, no backing out and no failures. All of these features at only .53 oz / 15 grams!
Features:
- Lightweight design at only .53 oz / 15 grams total
- Castle nut and end plate are 7075 T6 Aircraft Grade Aluminum
- Quick Detach Socket – 360º rotational locking interface
- No set screws or ratcheting systems that can’t be reused

Great for home builders
This is a fantastic endplate/castle nut. It's made of light and strong 7075 aluminum, locks up solidly, looks great, and even has a QD slot. I also appreciate that the ratchet can be easily retracted for removal.
USOnly castle nut I’ll ever buy
Ratcheting style is perfect. No worries about it ever backing out and so easy to install

Top notch! Has not budged.
USLight weight and works as advertised
I purchased this to avoid having to stake my castle nut on one particular AR and this system avoids the potential of a mil-spec castle nut coming loose. The color coating is a bit thin so expect to see some of the color coming off during install. But overall, well worth the money.
