The Geissele Automatics Super Duty MOD1-A SBR 5.56 13.9" Black is a short-barreled AR-platform rifle built around Geissele’s proven Super Duty architecture. Chambered in 5.56 NATO with a 13.9-inch threaded barrel, this compact setup is designed to deliver smooth shooting characteristics and dependable performance in a streamlined package. Its black finish and clean lines reflect Geissele’s focus on practical, purpose-driven design rather than unnecessary embellishment.

This Super Duty MOD1-A SBR is well suited for range use, training, and general-purpose defensive roles where a shorter overall length is beneficial. The 5.56 NATO chambering offers broad ammunition compatibility, while the threaded barrel allows the user to add a preferred muzzle device or suppressor. Built by Geissele Automatics, it reflects the company’s reputation for precise machining, robust components, and thoughtful engineering.
