Armaspec SRS-H Gen 4 AR-15 6-Position Buffer Tube Kit - Black

The Armaspec SRS-H Buffer Tube Kit is a complete drop-in assembly for mounting a stock to an AR-15 lower receiver. This Gen 4 kit pairs a mil-spec 7075-T6 aluminum 6-position buffer tube with Armaspec's signature Stealth Recoil Spring (SRS) system to deliver smoother cycling, reduced felt recoil, and improved reliability over a conventional buffer and spring.

The SRS-H pairs an enhanced multi-stage recoil spring with a standard-weight H buffer, giving shooters the recoil-mitigation benefits of the SRS platform without stepping up to the heavier H2 or H3 buffer masses. The kit ships with all the mounting hardware needed for installation: a steel castle nut and a steel end plate that lock the tube to any mil-spec AR-15 lower.

The tube carries a low-glare matte black finish that blends cleanly with factory and aftermarket AR-15 furniture. Six click-stop positions let the end user tune length of pull to suit a wide range of shooting stances, body types, and stock or pistol-grip configurations.

Designed for AR-15 platforms, the Armaspec SRS-H Gen 4 Buffer Tube Kit is a direct upgrade path for builders and end users looking to modernize the recoil system in a single drop-in package.
