The Timber Creek Outdoors Greyman Safety Selector Forest Aluminum (Model GAMBISSF, UPC 816397028172) is a premium ambidextrous AR-15 safety selector designed for shooters who want fast, intuitive controls, custom throw options, and a unique Forest Green aesthetic. As part of the Greyman series, this Greyman AMBI SS is a drop-in replacement for the OEM selector on any mil-spec AR-15 lower receiver, offering modular aluminum levers and the option to run either a traditional 90° throw or a short 45° throw to match your shooting style.
True Ambidextrous Safety Selector for AR-15 Lowers
The Greyman AMBI SS is built as a fully ambidextrous safety selector, giving both right- and left-handed shooters equal control:
Dual levers allow you to operate the safety from either side of the rifle—perfect for lefties and for shoulder transitions around cover.
Great for modern defensive, tactical, and competition shooting techniques, where ambidextrous controls are a must.
Compatible with mil-spec AR-15 lower receivers, making it an easy upgrade on most standard lowers.
If you’ve ever wished your selector worked equally well from both sides, this Greyman safety solves that with a smooth, reliable ambi design.
Configurable Throw: 90° or 45° Short-Throw
One of the standout benefits of the GAMBISSF Greyman Safety Selector is its adjustable throw angle:
Can be installed as a standard 90° throw from Safe to Fire.
Or set up as a 45° short-throw selector, allowing faster, more efficient on/off transitions.
Lets you choose the layout and function that best matches your training, muscle memory, and mission.
For competition shooters and defensive users, the 45° option can make the rifle feel noticeably quicker and more responsive, while traditionalists can stick with a classic 90°.
Modular Aircraft-Grade Aluminum Levers
Timber Creek builds the Greyman selector with modular levers made from aircraft-grade aluminum, emphasizing durability and customization:
CNC-machined from aircraft-grade aluminum for a strong yet lightweight control surface.
Modular long and short levers can be arranged to your preference—long on the primary side, short on the off side, or vice versa.
Textured / crosshatch surfaces (Greyman design) help ensure a positive, non-slip engagement, even with gloves or sweaty hands.
Compared to a basic mil-spec selector, this Greyman unit feels more tactile, deliberate, and confidence-inspiring when you move between Safe and Fire.
Forest Green Greyman Finish – Stand-Out Style with Purpose
The GAMBISSF variant comes in a distinctive Forest finish:
Color: Forest (Forest Green), clearly listed on multiple retailers as the Forest colorway in the Greyman line.
Adds a subtle, tasteful accent to your lower receiver, especially on rifles with OD, FDE, camo, or black components.
Pairs perfectly with other Greyman Forest parts—such as charging handles, dust covers, and buffer tubes—so you can build a cohesive green-accent rifle.
If you’re building a woodland or earth-tone AR, this selector is a small part that makes a big visual difference.
Drop-In Mil-Spec Compatibility & Complete Hardware
The Timber Creek Greyman AMBI SS is designed for straightforward installation:
Described by the manufacturer as a drop-in replacement for the OEM safety selector on any mil-spec lower receiver.
Includes all parts and hardware needed for installation, so you don’t need to reuse worn components.
Compatible with standard mil-spec fire-control groups; most aftermarket triggers work as well, though it’s always wise to confirm compatibility.
If you’re comfortable working on AR lowers, you can typically swap this safety in a short bench session with basic tools and a small punch set.
Enhanced Safety, Control & Speed
Upgrading your AR-15 safety selector isn’t just about looks—it can genuinely improve your handling and safety habits:
Faster engagement and disengagement means you’re more likely to keep the gun on Safe until you’re ready to fire, then quickly return it to Safe after.
Ambidextrous operation ensures you maintain safe handling even when shooting from your non-dominant shoulder or working around barricades.
Short-throw capability reduces the amount of movement required, which can be especially helpful in timed stages, defensive drills, or low-light scenarios.
For serious shooters, these small ergonomic gains can add up to more consistent, safer manipulation under stress.
Ideal for Duty, Defense, Competition & Custom Builds
The Timber Creek Greyman Safety Selector Forest Aluminum (GAMBISSF) is a great fit for:
Home-defense and duty carbines where ambidextrous controls and quick, positive safety operation are critical.
3-Gun and competition rifles that benefit from short-throw, modular selectors and faster transitions.
Custom AR-15 builds where you want premium small parts and color-matched Greyman components.
It’s a small part that serious shooters notice immediately every time they go on and off Safe.
