Armaspec SMB-H2 Gen3 AR-15 Buffer Kit 4.7oz Black/Silver

The Armaspec SMB-H2 Gen3 is a single-stage captured drop-in replacement for standard AR-15 buffer and spring. This 4.7oz H2 equivalent system uses a polymer base guide rod to prevent the buffer spring from rubbing the buffer tube's inner wall for smooth, quiet operation. It fits AR-15 carbine-length buffer tubes and includes the buffer, spring, and guide rod.

• Gen3 single-stage drop-in replacement
• 4.7oz H2 equivalent weight
• Polymer base prevents spring-tube contact

The SMB-H2 Gen3 provides interchangeable weights among C, H, H2, and H3 variants for AR-15 builds.
