The VLTOR A5 Receiver Extension Tube is purpose-built for shooters who demand a reliable, Mil-Spec buffer tube for their M4 or AR-15 platforms. Designed around the VLTOR A5 buffer system, this 7-position receiver extension offers a slightly longer profile than a traditional M4 tube, providing smooth stock adjustment and consistent alignment with collapsible stocks. Its black finish and clean, numbered position markings make it easy to set and repeat your preferred length of pull.

This receiver extension tube is compatible with Mil-Spec dimensioned M4/AR-15 collapsible stocks and can also serve as a replacement receiver extension for AR-10 rifles, giving it versatility across multiple builds. Ideal for range use, training, and general-purpose rifle setups, it supports dependable performance without unnecessary frills. The design reflects VLTOR Weapon Systems’ focus on practical engineering and proven durability in firearm accessories.
