Armaspec SMB Buffer Kit Gen 3 - Advanced Recoil Management System for AR-15 Platforms$86.39 – $86.84
Availability: In Stock
The Armaspec SRS Buffer Kit Gen 4 is a complete recoil management system designed for AR-15 pattern rifles. This kit bundles everything you need to mount a stock assembly on your lower receiver: a mil-spec 7075-T6 aluminum buffer tube with six adjustable positions, a steel castle nut, end plate, and Armaspec's SRS recoil buffer. Whether you're building a new AR from the ground up or upgrading an existing platform, this is a straightforward way to dial in the feel and performance of your rifle with a quality buffer system engineered to manage recoil consistently.
The SRS buffer represents Armaspec's multi-stage approach to recoil impulse. At 3.3 ounces, it's designed to work with AR-15 platforms to smooth out bolt carrier group travel and reduce felt recoil compared to standard mil-spec buffers. The six positions on the buffer tube give you the flexibility to tune for different loads, barrel lengths, and gas system configurations—handy if you run everything from lightweight varmint rounds to full-power hunting loads, or if you plan to swap uppers later. The mil-spec 7075-T6 tube itself is built tough and proven reliable across countless builds.
This kit takes the guesswork out of gathering individual components. You get the tube, buffer, castle nut, and end plate in one box, so no hunting through catalogs or worrying whether parts are compatible. Installation is straightforward for anyone with basic AR-15 assembly knowledge, and the whole package supports any stock that accepts a standard mil-spec buffer tube. If recoil management and modularity matter to you, this is a solid foundation for a purpose-built rifle.
