Forward Controls Design 4140 Billet Castle Nut - FDE Cerakote
- 4140 PH Steel construction
- Tough Flat Dark Earth 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.

It is just a castle nut, but with that said, compared to a standard Mil spec castle nut its clear which is of better quality. The FCD does weigh slightly more (at least feels like it) but it looks great. It just adds something extra to the rifle, over the same old parts. I'm happy with my purchase and I'll be putting them on all my builds.
<br>Of course PA shipped it very fast 👍👍
