Panzer Arms M4 Speed Features The Panzer Arms M4 Speed runs on an ARGO piston-driven gas system which keeps combustion byproducts out of the receiver and reduces the fouling that can affect direct impingement shotguns over time. This design choice is aimed at shooters who value reliability and low maintenance in a semi-automatic 12 gauge platform. The 18.5 inch barrel keeps the shotgun compact and maneuverable suited to close-quarters defensive scenarios as well as general range work. The semi-automatic action is built to keep pace with rapid strings of fire without excessive fouling buildup. The fixed skeleton stock keeps overall weight down for faster handling and quicker transitions between targets compared to bulkier furniture options. Finished in Black the M4 Speed presents a straightforward no-frills tactical profile that pairs well with a wide range of accessories. Its lightweight design philosophy makes the shotgun easier to maneuver in tight spaces than heavier tactical shotguns on the market. Built for shooters who want a fast reliable 12 gauge with proven piston-driven reliability the M4 Speed is a capable choice for defensive and recreational shooting alike.
