AR-15 A2 Rifle Buffer Tube Kit

The AR-15 A2 Rifle Buffer Tube Kit is a complete installation kit built for reliability and easy installation on rifles and carbine-length builds. The kit includes a properly sized A2/Mil-Spec buffer tube, hardened castle nut, receiver end plate (QD sling option available), buffer retainer and spring, and is compatible with standard rifle/carbine buffers and springs.

Choose from durable anodized or Cerakote finishes for corrosion resistance and a matched look. Each tube is precision-machined to standard Mil-Spec dimensions to ensure perfect fitment with commercial and aftermarket stocks and braces where specified.

Kit Includes: castle nut, end plate (standard or QD), buffer retainer pin & spring, and the A2/Mil-Spec buffer tube. Buffer and spring sold separately (choose correct carbine/rifle weight).
