Retay USA ACEMBL28 Ace 12 Gauge 3.5" 4-Round Semi-Auto Shotgun

The Retay USA ACEMBL28 Ace 12 Gauge 3.5" 4-Round Semi-Auto Shotgun delivers reliable semi-automatic performance in a platform purpose-built for tactical deployment, home defense, and sport shooting applications. Manufactured by Retay USA, this inertia-driven shotgun cycles both standard 2.75" and 3.5" magnum loads seamlessly, providing shooters with ammunition flexibility across diverse operational scenarios. The 4-round magazine capacity balances firepower with controllability, making it suitable for law enforcement training, civilian self-defense, and competitive shotgun sports where rapid follow-up shots demand a compact, dependable platform.

Built with a gas-operated inertia system, the Ace shotgun minimizes recoil impulse and ensures reliable cycling across ammunition weights without sacrifice of durability or long-term mechanical integrity. The semi-automatic action reduces shooter fatigue during extended training sessions and improves accuracy on successive shots by managing muzzle climb inherent to 12-gauge magnum loads. Weighing 10.64 pounds and measuring 39.2 inches overall, the shotgun provides a balanced point-of-aim and manageable profile for vehicle-based carry and indoor tactical environments. The reinforced receiver and smooth bolt carrier group support extended use without maintenance-induced downtime.

Law enforcement agencies, correctional facilities, and armed security teams benefit from the Ace's reliability with buckshot and slug loads, while sport shooters favor the platform for three-gun competitions and clay target disciplines. The 4-round capacity meets most jurisdictional compliance requirements for semi-automatic shotguns, and the inertia-driven design operates reliably in adverse weather and extreme temperatures without suppressor modification or additional tuning. Standard shotgun aftermarket accessories—magazine extensions, tactical lights, and rail-mounted systems—integrate seamlessly with the Ace's Picatinny-compatible furniture, enabling rapid customization for mission-specific loadouts.
