The Timber Creek Outdoors Greyman Safety Selector Black Aluminum (Model GAMBISSBL, UPC 816397028165) is a premium ambidextrous AR-15 safety selector designed for shooters who want faster manipulation, customizable throw distance, and a clean, modern look. Machined from aircraft-grade aluminum with modular levers and a sleek black finish, this Greyman AMBI SS is a drop-in replacement for the OEM selector on any mil-spec AR-15 lower receiver.
Ambidextrous Safety Selector – Built for Left- & Right-Handed Shooters
The Greyman AMBI SS is a true ambidextrous safety selector, giving you full control from either side of the rifle:
Dual levers allow operation with the thumb of the firing hand or the index finger of the support hand.
Ideal for left-handed shooters, off-shoulder transitions, and modern defensive/tactical techniques.
Enhances ergonomics when running low-mounted LPVOs, red dots, and magnifiers that can crowd traditional selectors.
If you’ve ever struggled to reach a standard mil-spec selector from your support side, this Greyman ambi safety solves that problem with smooth, intuitive control.
90° or 45° Short-Throw – Customize Your Throw Angle
One of the standout features of the GAMBISSBL Greyman Safety Selector is its configurable throw:
Can be installed as a traditional 90° throw (“Safe” to “Fire”) or as a 45° short-throw selector, depending on your preference.
Short-throw (45°) option allows for faster on/off transitions while keeping the selector movement tight and positive.
Great for competition, defensive use, and shooters who prefer minimal movement to go from Safe to Fire.
This adjustability lets you set up the rifle exactly how you like to run it, instead of being locked into a single configuration.
Modular Aircraft-Grade Aluminum Levers
Timber Creek designed the Greyman AMBI SS with modular aluminum levers for durability and customization:
Levers are CNC-machined from aircraft-grade aluminum for strength and light weight.
Modular design allows you to choose how you configure the long and short lever on each side to match your shooting style.
Crosshatch or textured surfaces (Greyman series) provide positive traction, even with gloves or sweaty hands.
Compared to bland mil-spec selectors, this Greyman unit gives you a more tactile, confidence-inspiring feel every time you move from Safe to Fire and back.
Drop-In Compatibility with Mil-Spec AR-15 Lowers
The GAMBISSBL Greyman Safety Selector is built for straightforward installation:
Drop-in replacement for OEM selectors on mil-spec AR-15 lower receivers.
Designed to work with most mil-spec trigger groups (a few aftermarket triggers may be incompatible—always verify fit).
Includes all parts and hardware needed for installation, so you don’t need to reuse old springs or detents.
If you’re comfortable stripping your lower and swapping fire control components, you can install this selector in a typical home workshop in just a few minutes.
Sleek Black Greyman Finish – Clean, Modern Aesthetic
Finished in a deep, durable black anodized coating, the GAMBISSBL selector fits seamlessly into virtually any build:
Color: Black – matches standard receivers, grips, and triggers for a cohesive look.
Part of the Greyman series, which focuses on low-profile, purpose-built styling rather than flashy graphics.
Coordinates perfectly with Greyman charging handles, dust covers, and other small parts in Black, Urban, Desert, Forest, or Stealth if you’re doing a multi-color build.
Whether you’re building a duty rifle, competition carbine, or home-defense AR, this selector looks right at home.
Enhanced Control, Safety & Speed
Upgrading to a quality ambidextrous selector like the Greyman AMBI SS offers real performance benefits:
Faster transitions between Safe and Fire during drills, competitions, and real-world encounters.
Easier to keep your firing hand in place while activating the selector with your thumb or knuckle.
Allows mirror-image operation when shooting from the support shoulder, improving safety and ergonomics around cover.
When your selector is easier and more intuitive to manipulate, you’re more likely to use it properly and consistently, which is a real gain in overall rifle safety.
Ideal for Duty, Defense, and Custom AR Builds
The Timber Creek Greyman ambidextrous safety selector is an excellent choice for:
Home-defense and duty carbines where ambidextrous controls are a significant advantage.
Competition rifles that benefit from fast, short-throw selectors.
Custom AR-15 builds where high-end controls and matching Greyman components are part of the plan.
Its blend of modularity, smooth function, and rugged aluminum construction makes it a smart upgrade over basic single-side selectors.
