5-Inch Black Barrel for Enhanced Accuracy and Velocity

The ATC Base is equipped with a 5-inch black barrel that provides increased muzzle velocity and improved sight radius compared to compact models. This longer barrel enhances accuracy at distance while maintaining excellent balance and shootability. The black finish offers corrosion resistance and a sleek appearance. Whether engaging targets at 25 yards or beyond, the 5-inch barrel gives shooters a competitive edge in both speed and precision.

Nitrocarburized Stainless Steel Slide with Lightening Cuts

The slide is constructed from stainless steel and treated with a nitrocarburizing process for exceptional hardness and corrosion resistance. Lightening cuts reduce the overall weight of the slide, improving cycling speed and reducing felt recoil. Aggressive serrations on both the front and rear of the slide provide a secure grip for chambering rounds or clearing malfunctions, even when wearing gloves or in wet conditions. The combination of durability and reduced weight makes this slide ideal for high-round-count training and competition.

Optic Cut Slide for Modern Red Dot Mounting

The ATC Base comes with a factory optic cut, allowing shooters to easily mount popular red dot sights such as Trijicon RMR, Holosun, and others. This feature eliminates the need for aftermarket milling and provides a lower 1/3 co-witness or absolute co-witness option depending on the optic and mounting plate used. The optic-ready design makes the pistol highly adaptable to current trends in competitive and defensive shooting.

Aluminum Frame with Beavertail and Picatinny Rail

The lightweight aluminum frame features a beavertail that helps prevent slide bite and improves control during rapid fire. The integrated Picatinny rail on the dust cover allows for the attachment of weapon lights, lasers, or other accessories. This combination of features enhances both handling and versatility, making the ATC Base suitable for a wide range of applications from competition to home defense.

High-Capacity 20+1 Magazine

The Steyr ATC Base comes with a 20-round magazine, offering significant firepower for competitive stages and defensive situations. The high-capacity magazines are designed for reliable feeding and smooth reloading, giving shooters an advantage in dynamic shooting environments where speed and capacity are critical.
