Armaspec SRS-H2 Gen 4 AR-15 6-Position Buffer Tube Kit

The Armaspec SRS-H2 Gen 4 AR-15 Buffer Tube Kit is a complete buffer-tube and recoil-system assembly for AR-15-pattern firearms. It provides the receiver extension hardware used to mount a stock assembly and replaces a conventional buffer and spring with Armaspec's self-contained, multi-stage SRS-H2 recoil system.

The kit includes the SRS Gen 4 H2 recoil system, a six-position mil-spec buffer tube, end plate, and castle nut. The buffer tube is made from 7075-T6 aluminum, while the end plate and castle nut are steel. All components have a matte black finish.

The H2 configuration has a 4.7 oz equivalent buffer weight, and the complete kit weighs 7.4 oz. Its enclosed recoil assembly prevents the spring from rubbing against the buffer tube's inner wall, while the system's second stage is designed to reduce felt recoil.

This buffer tube kit is offered in New Condition.
