The 2A Armament AR-10 Carbine Buffer Tube is a must for AR builders who want to minimize headaches in the building process. It self-aligns with the buffer detent. You can also use it in AR-15 builds. It's a great choice because of its durability, optimized design, and user-friendly features. At 3.99 ounces, it's also a lightweight choice.
If you want versatility, this buffer tube offers a total of five adjustment options. One is fully collapsed, and there are four additional positions.
The 2A Armament AR-10 Carbine Buffer Tube is made from 6061-T621 aluminum. For added durability, it has a Type III Class 2 anodized hard coat. It's also vented to support reliability and prevent any liquid that accidentally enters it from being retained.
If you like a length of pull that's just a little longer than the standard AR-15, the 2A Armament AR-10 Carbine Buffer Tube is 5/8" longer. You may notice improved comfort, accuracy, and control if that's your ideal length of pull.
