Introducing the 2A Armament AR-10 Buffer Tube, a lightweight accessory designed to elevate your shooting experience with its array of features. Crafted from billet machined 6061-T651 aluminum, this buffer tube offers tighter concentricity than traditional forging or impact extrusion methods, minimizing the risk of bolt carrier binding. With a thread diameter of 1.185 and a Mil-Spec extension diameter of 1.148, it ensures compatibility with a broad range of AR-10 rifles.

The standout feature of this buffer tube is its 8-position adjustment with machined indicators conveniently located at the stock latch pin. This design facilitates easy selection of your preferred length of pull, providing enhanced customization options with extended positions and finely spaced increments. The lightening flutes along the tube reduce overall weight without compromising durability, while the extended carrier support flange ensures improved anti-tilt performance.

Installation is simplified by the self-aligning feature with the buffer detent, and the chamfered edges on the stock guide ramps contribute to a comfortable feel. With a carbine length of 8 inches, this buffer tube is tailored for AR-10 rifles. Vented for efficient heat dissipation, it prevents overheating during prolonged shooting sessions. Despite its robust construction, the buffer tube weighs only 3.65 oz, minimizing additional weight on your rifle.

Upgrade your AR-10 rifle with the 2A Armament AR-10 Buffer Tube to experience improved performance and comfort. Whether you’re a seasoned shooter or a novice, this finely crafted buffer tube enhances your shooting experience and contributes to optimal accuracy. Take control of your rifle’s length of pull and enjoy the benefits of this meticulously designed buffer tube.
