When evaluating semi-automatic shotguns for duty, home defense, or range work, reliability and straightforward controls are the baseline. A platform that cycles cleanly, accepts common defensive loads, and provides sighting options for rapid target acquisition stands out in real-world use.

CENTURY ARMS CENTURION A4 [BLK] is a purpose-built 12 gauge semi-automatic that blends a gas piston operating system with a compact, 20 inch barrel and a 3 inch chamber for broad ammo compatibility. The A4 comes with a Ghost Ring rear sight and a fiber optic front sight for fast, repeatable sight picture, a 5+1 magazine tube for immediate readiness, and a Picatinny top rail to mount optics or red dots. The all-black Cerakote finish provides corrosion resistance and a low-profile look at a street price of $219.99. Shop this product

Design and key features

The A4’s gas piston system is the centerpiece for reliability — it minimizes carbon fouling at the receiver and bolt face, promoting consistent cycling with a mix of factory buckshot and defensive loads. The 20 inch barrel keeps the package maneuverable while preserving pattern density at practical engagement distances. A 3 inch chamber gives users the flexibility to run 2 3/4″ or 3″ shells, expanding load choices for feeding, recoil management, and terminal performance.

Sighting and accessory readiness

The combination of a Ghost Ring rear and fiber optic front sight produces a fast, instinctive sighting system for close-to-mid range scenarios. For operators who prefer optics, the Picatinny top rail allows low-profile red dot installations without permanent gunsmithing.

Century Arms is known for offering rugged equipment at accessible price points, and the CENTURY ARMS CENTURION A4 [BLK] follows that approach while packing tactical features found on higher-priced shotguns. View product details and pricing

Performance and applications

For home defense, the 5+1 capacity keeps the platform compact and ready; for training and recreational shooting, the gas piston helps reduce cleaning time and improves time-on-target between strings. The Cerakote finish enhances wear resistance in field or range environments. Whether used for security teams or responsible private ownership, the A4 balances cost, capability, and durability.
