Armaspec SMB Gen 3 Buffer-H2 Kit, Black - Superior Recoil Control with Advanced Buffer Technology - ARM268-H2

Overview

The Armaspec SMB (Sound Mitigation Buffer) Gen 3 Kit is a drop-in, single-stage captured buffer system designed for AR-15 platforms. This H2-type buffer kit is engineered to replace standard mil-spec buffer springs and weights to provide smoother, quieter operation by preventing spring-to-tube contact. The system features a 4.7 oz equivalent weight and is designed to reduce felt recoil and optimize bolt carrier group dynamics. The complete kit includes the SMB buffer, buffer tube, end plate, and castle nut, making it suitable for custom AR builds across various barrel lengths. The buffer spring can be trimmed if necessary to reduce tension, and the system is compatible with modern AR configurations, including those using suppressors.
