Details
Features:
- 4140 PH Steel construction
- Tough Olive Drab Green Cerakote finish
- 25% longer staking notches
- Additional notch added
- Coarse serrations for easy installation
Military specifications require castle nuts to be staked in two locations to ensure the castle nut and buffer tube will not loosen without deliberate action, and FCD believes this is one of those points where less is definitely not more. Traditional MIL-SPEC castle nuts have 3 staking notches, the CNF features 4, ensuring at any time three are available to be used. Each notch has also been upgraded to a deep, 30-degree cut, making them 25% longer than MIL-SPEC to ensure enough material can be staked into the notch for secure installation. To make threading the castle against the end plate even easier, the outer edge features coarse serrations.
Forward Controls Design firmly believes in the elegance of simplicity. Not content to produce purely aesthetic components, they put function before form to create parts and accessories that actually improve the handling and function of your firearms. When you need parts that just work without complication, you need Forward Controls Design.

Will not thread onto the buffer tube
by Joshua -
I took it out of the package, removed the old castle nut with ease. Tried over and over to thread this Forward Controls castle nut onto the buffer tube. It’s either the size is just slightly to small or there’s entirely too much Cerakote on the threads. I tried using a wire brush to slightly remove some Cerakote off the threads with a little WD-40 to at least help it go on. Again it just wasn’t happening, I marred up the ODG finish a little bit fighting with it and finally gave up.
