The Century Arms Centurion A4 Piston Driven Shotgun

Centurion A4 Overview and Specifications

The video focuses on the Centurion A4 semi-automatic piston driven shotgun, imported by Century Arms. Technical specifications are outlined first: the shotgun weighs 8.63 pounds according to the listed specs and offers a 5+1 capacity. It is chambered in 12 gauge with a 3-inch chamber and uses a 20-inch barrel. Overall length is 41.7 inches. The gun ships with a single choke already installed, and the host notes that adjustable chokes are available, though only one is included in the box. The configuration is presented as a straightforward 12 gauge semi-automatic platform with a tubular magazine and piston system.

Sights, Rail, and Customization Options

Attention then turns to the shotgun from muzzle to receiver. The Centurion A4 features a raised red fiber optic front sight that is adjustable and mounted directly to the barrel. A tubular magazine runs beneath the barrel and connects to a polymer foregrip with grooves designed to improve purchase, especially when hands are sweaty or under recoil from 12 gauge loads. On top, there is a metal Picatinny rail that can accept various red dot optics, while the included adjustable front and rear sights are polymer. Under the Picatinny rail is a dovetail, allowing the rail to be removed and replaced with more traditional sights if desired, giving the user some flexibility in sighting options.

Controls, Trigger Feel, and Ergonomics

The shotgun uses a metal charging handle with a corrugated design and lightening holes, intended to stay cool and provide a distinctive look. The bolt carrier group cycles smoothly out of the box, and the silver feed ramp is both visually distinctive and notably smooth, avoiding the gritty feel sometimes found on new shotguns. The trigger guard and trigger are polymer. After confirming the chamber is clear, the host describes the trigger as having a small amount of take-up, a very solid wall, and a clean break with no additional movement past the wall. The semi-automatic action provides a tactile reset, making follow-up shots straightforward. The grip is rubber over a polymer core, with finger grooves that enhance control and prevent slipping even when hands are sweaty.

Stock, Recoil Management, and Value

Moving to the rear, the Centurion A4 has a polymer buttstock equipped with a sling swivel mount on the bottom. A large rubber butt pad is fitted to help mitigate the recoil associated with 12 gauge shells, which are known for having more kick than some shooters may be used to. The shotgun is described as a sub-400-dollar piston driven model with a 5+1 capacity and a 20-inch barrel. The build feels solid, with the rail, furniture, and controls giving an impression of durability. Overall, the host characterizes the shotgun as offering strong value for the price, particularly considering the piston system, Picatinny rail, and general fit and finish.

Measuring Length, Height, and Trigger Weight

The testing segment begins with physical measurements. Using a tape measure, the overall length is confirmed at approximately 41.5 inches, aligning closely with the listed 41.7 inches. With the iron sight installed, the total height is about 6.5 to 6.7 inches. The trigger pull is then gauged multiple times to find an average. The first pull measures 6.6 pounds, heavier than expected. A second pull reads 4.9 pounds, and a third pull comes in at 4.1 pounds. Averaging these results places the trigger pull around the 5-pound mark. The host emphasizes that, regardless of the exact number, the trigger feels very good in use, with a clean break and positive reset.

Weighing the Shotgun and Final Thoughts

The shotgun is then placed on a scale to verify its actual weight. The reading shows 8.6 pounds, which is slightly lighter than the 8.63 pounds quoted in the specifications. This confirms that the listed weight is accurate, if a bit conservative. The video concludes by reiterating that the Centurion A4 semi-automatic piston driven shotgun, with its 20-inch barrel and 5+1 capacity, represents strong value out of the box. The build quality, smooth action, usable sights, and comfortable ergonomics stand out.
