AR-15 – Ambi Safety Selector – SLS Fifty – Color
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Fortis SLS Fifty is an ambidextrous AR-15 safety selector built around Fortis’ RidgeKey locking system with no visible screws, 6061-T6 aluminum levers, and a black-nitrided 4140 steel core. It is a standard two-position selector with built-in 50 and 90 degree options.
Available options are organized below under Variants. Verified colors in this batch are Flat Dark Earth, Gold, and Olive Drab Green.
Fitment
- Fits AR-15 pattern rifles
- Ambidextrous design
- Standard two-position safety selector
- Built-in 50° and 90° throw options
Does NOT fit
- Do not treat this as a three-position or forced-reset style selector
- Verify compatibility with your trigger and lower parts setup before purchase
What it does
This replaces the factory selector with a cleaner ambi setup that gives left- and right-handed manipulation plus configurable throw options. In real use, it is about better control, faster engagement, and a more refined feel at the thumb.
Why it’s worth it
The design is legit, the features are good, and the no-visible-screw setup is cleaner than the usual stuff. The only kick in the teeth is pricing—your profitable number sits above Fortis direct, so this is not a “cheap AR upgrade” play.

Install notes
Selector installs are straightforward, but still worth doing carefully. Confirm detent feel, function, and safe operation before live fire. If your trigger setup has selector-specific quirks, verify that before blaming the safety.
Verify before you buy
Verify you are buying for an AR-15 lower and not assuming fitment across every random receiver or trigger setup under the sun.
