Fortis Manufacturing SLS FIFTY Safety Selectors Review

Real Insights into the **Fortis Manufacturing SLS FIFTY Safety Selectors**

As someone who has spent over a decade putting gear through its paces in demanding environments – from the dust of a workshop to the precision of a lab bench, and out in the rugged field – I approach new equipment with a healthy dose of skepticism and an eye for detail. My recent acquisition, the Fortis Manufacturing SLS FIFTY Safety Selectors, was born out of a specific need for a more robust and aesthetically pleasing upgrade to the standard selector on my AR-15 platform rifle. The factory selector, while functional, always felt a bit… generic. I was looking for something that offered not just improved ergonomics but also a noticeable step up in build quality and a unique locking mechanism to ensure reliability. My search led me to Fortis Manufacturing, a brand known for its innovative approach to firearm components. Compared to the plethora of common aftermarket selectors that rely on standard screws, the SLS FIFTY’s patent-pending RidgeKey system immediately caught my attention. Upon first handling these selectors, my initial impression was one of solid engineering; the weight, the clean lines, and the feel of the material all suggested a product built to last. This initial positive reaction was a welcome change from the often disposable feel of some firearm accessories.

Real-World Testing: Putting **Fortis Manufacturing SLS FIFTY Safety Selectors** to the Test

First Use Experience

My primary testing grounds for the Fortis Manufacturing SLS FIFTY Safety Selectors were at the indoor shooting range and during routine maintenance sessions at my workbench. The installation process, while generally straightforward for anyone familiar with AR-15 platforms, did require a bit of finesse to ensure the RidgeKey mechanism engaged correctly. I found myself referencing the installation instructions a couple of times to get the orientation just right, a minor hurdle that speaks to the unique nature of its locking system. Once properly seated, the difference in tactile feedback was immediate. The selectors moved with a satisfying, positive detent, feeling significantly more secure than my previous component.

Over several range days, I subjected the selectors to rapid fire, various grip styles, and even the occasional fumbled reloads. The Fortis Manufacturing SLS FIFTY Safety Selectors performed admirably, maintaining their secure fit and smooth operation. I intentionally exposed the rifle to typical range dust and the light moisture from my hands without issue. The ambidextrous design also proved invaluable, allowing for quick safety manipulations regardless of my shooting stance or whether I was using my primary or support hand.

Extended Use & Reliability

After several months and numerous range trips, the Fortis Manufacturing SLS FIFTY Safety Selectors have proven their worth. They’ve become a seamless part of the rifle’s operation, a component I no longer consciously think about because it simply works. There are no signs of loosening, no play in the levers, and the black nitride finish on the core remains smooth and free of any significant wear, even with repeated manipulation. Cleaning is as simple as a quick wipe-down during rifle maintenance, and the design doesn’t trap excessive debris.

In direct comparison to other aftermarket selectors I’ve used, including some that were considerably more expensive, these Fortis units strike an excellent balance between innovative design and practical reliability. While some budget options might offer ambidextrous control, they often compromise on the locking mechanism or material quality. The Fortis Manufacturing SLS FIFTY Safety Selectors feel like a substantial upgrade, a thoughtful piece of engineering that enhances both function and form.

Breaking Down the Features of **Fortis Manufacturing SLS FIFTY Safety Selectors**

Specifications

The Fortis Manufacturing SLS FIFTY Safety Selectors are engineered with precision and durability in mind. The selector levers are crafted from 6061-T6 Aluminum, a material prized for its excellent strength-to-weight ratio, making them lightweight yet robust. These levers feature a distinctive cutout design that allows a glimpse of the selector core, adding a touch of visual flair. The core itself is constructed from 4140 Steel, a high-strength alloy known for its toughness and resistance to wear. This core is finished with a black nitride coating, which provides a smooth surface and exceptional resistance to abrasion. An optional TiN (Titanium Nitride) coating is also available for even greater durability and a distinct aesthetic.

These selectors offer a medium length, which is an optimal balance for accessibility and avoiding snags. They are designed with built-in options for both 50-degree and 90-degree throw selections, allowing users to tailor the throw angle to their preference and shooting style. The most significant innovation is the robust RidgeKey locking mechanism, a patent-pending system that secures the levers to the core without visible screws. This eliminates common failure points found in other designs, where screws can loosen or break. The entire unit is ambidextrous, catering to both left and right-handed shooters with equal functionality.

Performance & Functionality

In terms of core function, the Fortis Manufacturing SLS FIFTY Safety Selectors excel. The primary job of a safety selector is to positively and reliably engage or disengage the fire control group, and these selectors do so with remarkable crispness. The detents are well-defined, providing a distinct click into Safe, Fire, and any intermediate positions if a 90-degree throw is selected. The ambidextrous levers are ergonomically shaped with strategically placed serrations that offer excellent grip, even with sweaty hands or gloves.

The standout feature is undoubtedly the RidgeKey locking mechanism. This system completely removes the concern of set screws backing out, a common frustration with other aftermarket selectors. This patent-pending design ensures that the levers are locked securely to the core, creating a solid point of contact and a system that feels remarkably integral. This translates to consistent performance under stress; there’s no wiggle, no doubt, just a reliable switch. The medium length offers just the right amount of purchase for quick manipulation without being overly bulky.

Design & Ergonomics

The design of the Fortis Manufacturing SLS FIFTY Safety Selectors is a clear departure from the mundane. The 6061-T6 Aluminum levers are sculpted with clean lines and feature an attractive cutout that offers a peek at the black nitride coated 4140 Steel core. This visual element not only looks great but also subtly highlights the robust construction beneath. The finish on both the levers and the core is excellent, providing a premium feel that complements a well-built firearm.

Ergonomically, these selectors are a significant improvement. The ambidextrous levers are shaped to be easily manipulated by the index finger of the support hand or the thumb of the shooting hand. The strategically placed serrations are aggressive enough to provide positive traction but are not so sharp as to cause discomfort during prolonged use. The medium length strikes a perfect balance; it’s easy to reach and operate, but not so long that it interferes with grip or other controls. The 50 and 90-degree options cater to individual preferences, allowing for a faster or more deliberate safety transition.

Durability & Maintenance

Given the materials and construction, the Fortis Manufacturing SLS FIFTY Safety Selectors are built for longevity. The 4140 Steel core with its black nitride finish is inherently wear-resistant, designed to withstand countless cycles of engagement and disengagement. The 6061-T6 Aluminum levers are also durable, capable of resisting impacts and scratches that might mar lesser components. The key differentiator here is the RidgeKey locking mechanism, which, by eliminating screws, removes a primary point of potential failure over time.

Maintenance is virtually nonexistent beyond standard rifle cleaning. The nitride finish is easy to wipe down, and the lever design doesn’t readily trap dirt or debris. Unlike screw-based systems that may require periodic tightening, these selectors offer a set-it-and-forget-it level of reliability. I’ve experienced no degradation in function or appearance, even after extensive use, suggesting a product that will likely outlast many other components on an AR-15.

Accessories and Customization Options

The Fortis Manufacturing SLS FIFTY Safety Selectors are primarily a standalone upgrade, meaning they don’t typically come with a wide array of accessories. However, the critical customization option lies within the selector core itself: the choice between a standard black nitride finish and a more striking TiN (Titanium Nitride) coating. This choice impacts both durability and aesthetics, allowing users to personalize their build further.

The ambidextrous design inherently provides customization by accommodating both left- and right-handed shooters without needing separate parts. Furthermore, the option to select between a 50-degree and 90-degree throw is a significant ergonomic customization that allows shooters to tailor the safety lever’s travel distance to their personal preference and shooting technique. This level of user-configurable functionality is a key aspect of its appeal.
