AR-15 Rifle Receiver Extension Tube

Make: AR-15
Make/Model: AR-15
Style: A2


Maker: Brownells
Model: Function: The buffer tube houses the buffer and recoil spring, which are essential components in the AR-15's recoil system. When the rifle is fired, the buffer and spring absorb and mitigate recoil, allowing for the cycling of the firearm. Types: There are two main types of buffer tubes—commercial and mil-spec. While they serve the same function, they have slight dimensional differences, and it's important to ensure compatibility with other stock and buffer components. Material: Buffer tubes are typically made of aluminum. The material choice ensures durability while keeping the overall weight of the rifle manageable. Lengths: Buffer tubes come in different lengths, and the choice of length can affect the length of pull (distance from the trigger to the buttstock) of the rifle. Common lengths include rifle, carbine, and pistol buffer tubes. Threads: The buffer tube has threads at its rear end where the castle nut is tightened to secure the receiver end plate and the buttstock. Attachment of the Buttstock: The buffer tube allows for the attachment of various types of buttstocks, providing customization options for the user based on personal preference and shooting style.
