The Veltor buffer tube system sets the standard for modularity and ruggedness, offering a solid foundation for your AR-15 build. What sets our version apart is the Forward Controls Design's enhanced castle nut. Engineered for durability and ease of use, this castle nut integrates seamlessly with the Veltor system, providing a secure lock without the need for staking. Its anti-rotational features ensure your stock stays put under the harshest conditions, making it a must-have for any serious shooter.

• Staking notches angle changed from 45 to 30 degrees, this results in longer (25% longer than TDP spec) and deeper notches than found on TDP castle nuts.
• Number of staking notches increased from 3 to 4, spaced equally on the CNF. The castle nut is to be staked in two places, we’re not advocating staking in more than two places, CNF’s 4 staking notches mean that, at all times, 3 will be visible and available for staking, it simply gives the user more staking location options.
• Coarse serrations on the wrench side of the nut, a single-use feature to make it easier while rotating the CNF towards the endplate.

When you choose the CN5F, you're investing in a component that brings military-grade reliability to your firearm. Its secure staking and high-quality materials make it the go-to choice for professionals and enthusiasts alike.
