The Armaspec ARM263-9 SRS-9 Buffer Tube Kit Black AR-15 Gen4 is a complete recoil management upgrade for AR-15 and AR-9 pattern rifles. This kit combines a mil-spec 7075-T6 aluminum 6-position buffer tube with Armaspec’s Stealth Recoil Spring (SRS) Gen4 system, delivering smoother cycling and more consistent performance. The self-contained multi-stage buffer and spring assembly is engineered to minimize friction inside the tube, resulting in quiet operation and a noticeable reduction in felt recoil.

Ideal for range use, training, and refining a dedicated PCC or AR-15 build, this buffer kit provides all the core components needed to mount a stock assembly onto a lower receiver: buffer tube, steel castle nut, end plate, and SRS-9 buffer. The 6.4 oz multi-stage buffer weight is tuned for enhanced control, helping shooters stay on target through rapid strings of fire. It’s a practical upgrade for anyone looking to improve reliability and shooting comfort while benefiting from Armaspec’s focus on thoughtful design and precision manufacturing.
