Overview
Built for 9mm blowback AR-15 setups, this buffer kit provides the buffer weight and components needed for proper cycling in an AR-9 carbine. It includes a 5.4 oz carbine buffer, carbine buffer spring, and aluminum buffer spacer, giving you the parts required for this specific configuration rather than a standard rifle or carbine buffer. The matte black finish on the all-steel buffer kit adds a practical layer of protection against surface wear.

- The kit is focused on buffer components only; it does not include other parts needed for a complete build or conversion.
- The description calls out a matte black finish for surface protection, but it does not provide detailed performance data beyond that.
- Compatibility is framed around 9mm AR-15 use, so buyers should verify their platform requirements before ordering.
