Fortis Manufacturing Super Lean Sport/SLS FIFTY Safety Selector Review

Let’s Talk About Fortis Manufacturing Super Lean Sport/SLS FIFTY Safety Selector

It’s easy to overlook the small parts when building or upgrading an AR-platform rifle, but the safety selector is a critical interface. Fortis Manufacturing aims to elevate this often-overlooked component with their Super Lean Sport/SLS FIFTY Safety Selector, promising enhanced ergonomics and reliability. I was looking to upgrade my current mil-spec selector for something that provided a more positive and tactile feel.

After years of dealing with gritty, ill-defined safety switches, I was seeking a smoother, more responsive option. The Fortis design piqued my interest with its promise of a robust, screw-less locking mechanism and the option for both 50-degree and 90-degree throws. Unboxing the SLS FIFTY, I immediately noticed the clean lines and the aggressive serrations on the levers. The overall impression was one of quality and precision, a stark contrast to some of the MIM (Metal Injection Molded) selectors I’ve encountered.

Compared to a standard mil-spec selector and a competing ambi selector from Radian, the Fortis SLS FIFTY distinguished itself. While the mil-spec is functional but basic, and the Radian is robust, the Fortis offered a unique combination of streamlined design and innovative locking. I ultimately chose the Fortis due to its promise of enhanced durability and the sleek, screw-less design. My first impression was excitement; I was eager to install it and see if it lived up to the hype.

Real-World Testing: Putting Fortis Manufacturing Super Lean Sport/SLS FIFTY Safety Selector to the Test

First Use Experience

I tested the Fortis Manufacturing Super Lean Sport/SLS FIFTY Safety Selector primarily at my local outdoor shooting range. The conditions were typical for a Southern California afternoon: sunny, dry, and slightly dusty. Right away, the difference in feel was noticeable.

The shorter, 50-degree throw felt incredibly intuitive and fast, especially when transitioning between safe and fire. There were no issues after the first range trip.

Extended Use & Reliability

After several months of use, including multiple range sessions and a carbine course, the Fortis SLS FIFTY has held up admirably. I’ve put roughly 1,000 rounds through the rifle since installing the selector. There are no visible signs of wear on the aluminum levers or the black nitride-coated core.

Maintenance is straightforward, requiring only occasional cleaning and lubrication of the detent contact points. Compared to my previous experiences with mil-spec selectors that often became gritty over time, the Fortis remains smooth and reliable. It definitely outperforms my expectations and has quickly become one of my favorite upgrades on my AR.

Breaking Down the Features of Fortis Manufacturing Super Lean Sport/SLS FIFTY Safety Selector

Specifications

• Material: The selector levers are constructed from 6061-T6 Aluminum, offering a lightweight yet durable solution. The 6061-T6 aluminum provides a good balance of strength and weight.
• Selector Core: The core is made from 4140 Steel, which has been coated in black nitride (with an optional TiN finish available). This provides exceptional wear resistance and a smooth operating surface.
• Ambidextrous Levers: These offer easy manipulation from either side of the rifle. It’s crucial for left-handed shooters or for those who prefer ambidextrous controls.
• 50/90 Degree Throw Options: Allows the user to select between a shorter, faster 50-degree throw or a more traditional 90-degree throw. This versatility caters to individual preferences and shooting styles.
• RidgeKey Locking Mechanism: Fortis’s patent-pending system secures the levers to the core without visible screws. This eliminates potential weak points associated with traditional screw-based designs.

Performance & Functionality

The Fortis Manufacturing Super Lean Sport/SLS FIFTY Safety Selector excels in both performance and functionality. The option for a 50-degree throw is a game-changer, allowing for incredibly fast transitions between safe and fire. The positive, tactile feedback ensures confident operation.

The only potential weakness is the initial installation, which can be slightly tricky due to the RidgeKey locking mechanism. However, once installed correctly, the selector performs flawlessly and exceeds expectations.

Design & Ergonomics

The Fortis selector features a streamlined, minimalist design. The 6061-T6 aluminum levers are lightweight and comfortable to manipulate. The strategically placed serrations offer excellent grip without being overly aggressive.

The overall build quality is top-notch, with precise machining and a durable finish. There’s a slight learning curve associated with the RidgeKey system, but the improved ergonomics and positive feedback are well worth the effort.

Durability & Maintenance

Given the materials and construction, the Fortis Manufacturing Super Lean Sport/SLS FIFTY Safety Selector is built to last. The black nitride coating on the steel core provides excellent corrosion and wear resistance. Regular cleaning and lubrication, as with any firearm component, will ensure long-term reliability.

Disassembly for cleaning requires a punch tool and some patience due to the RidgeKey system. However, this is a minor inconvenience compared to the overall durability and performance.

Accessories and Customization Options

The Fortis SLS FIFTY doesn’t come with many accessories, focusing instead on the core functionality of the safety selector itself. While Fortis offers the selector with different lever colors (black or red), customization is primarily limited to selecting the desired throw angle (50 or 90 degrees). The selector is compatible with standard AR-15 lower receivers and fire control groups.
