AR15 Castle nut


The RBA AR15 Castle Nut is a vital component in the assembly of an AR-15 rifle. Crafted with precision and designed for durability, this castle nut plays a crucial role in securing the buffer tube and ensuring the reliability of your firearm.

Key Features:

  1. Secure Buffer Tube Attachment: The primary function of the castle nut is to securely fasten the buffer tube to the lower receiver of the AR-15. This ensures that the buffer assembly functions as intended, allowing for proper cycling of the firearm.
  2. Durable Construction: The RBA AR15 Castle Nut is built to last. Constructed from high-quality materials, it can withstand the rigors of regular use and the recoil forces generated during firing.
  3. Staking Compatibility: This castle nut is designed with staking in mind. Staking involves using a specialized tool to deform a portion of the end plate into one of the notches on the castle nut. This process creates a permanent and secure attachment, preventing the castle nut from loosening over time.
  4. Versatile Use: Whether you’re assembling a new AR-15 rifle, replacing worn components, or customizing your firearm, the RBA AR15 Castle Nut is a versatile accessory that ensures the buffer tube assembly functions reliably.
  5. Ease of Installation: Installing the castle nut is a straightforward process, especially when following proper guidelines. However, it’s essential to ensure that it is correctly tightened and staked to prevent any chance of loosening during firing.
  6. Compatibility: The RBA AR15 Castle Nut is designed to be compatible with a wide range of AR-15 lower receivers and buffer tubes, making it a practical choice for many firearm enthusiasts.
  7. Enhanced Rifle Reliability: By securely fastening the buffer tube, the castle nut contributes to the overall reliability and safety of your AR-15. A properly installed castle nut helps maintain consistent cycling of the rifle.

In summary, the RBA AR15 Castle Nut is a critical component in the assembly and maintenance of your AR-15 rifle. Its role in securely fastening the buffer tube, along with its durability and compatibility, makes it an essential accessory for any AR-15 owner. Properly installed, this castle nut ensures the reliability and performance of your firearm, giving you confidence in your shooting experience.
