If you're in the market for a compact, reliable optic for competition, self-defense, or concealed carry, the Cyelee Chameleon G-SRS8 deserves your attention. Recently, I had the opportunity to put this green dot sight through its paces mounted on my Fusion Firearms XF Pro, and today I'm sharing my experience.

Right out of the box, the Cyelee Chameleon G-SRS8 impresses with its balance of lightweight design and robust construction. Crafted from aircraft-grade 7075-T6 aluminum, this optic weighs just 1.4 ounces, making it ideal for setups where every ounce matters. A standout feature is its top-mounted CR1632 battery compartment, which allows battery replacement without removing the optic—a major convenience.

With an IPX7 waterproof rating, the G-SRS8 easily withstands rain, dust, and general wear and tear common to serious range or carry conditions. Its RMR footprint compatibility also ensures seamless integration with popular optic-ready pistols from Glock, SIG, FN, and more. Priced at an affordable \$199.99, it delivers impressive quality without breaking the bank.

One of the most notable features of the G-SRS8 is its 8 MOA green dot reticle, significantly larger than typical red dots. This design choice enhances rapid target acquisition—essential for competition or self-defense scenarios. Additionally, Cyelee's innovative STIG-RS system is tailored specifically for shooters with astigmatism, effectively minimizing common issues like starbursting and distortion. The optic offers 10 brightness settings, including two dedicated night vision settings. During my range sessions, I found the dot crisp and clear, even at lower brightness levels, without sacrificing speed or accuracy.

Mounting the G-SRS8 is straightforward, thanks to the standardized RMR footprint. Controls are streamlined, featuring two recessed push buttons for adjusting brightness. The viewing window measures 26.5mm by 22.5mm, providing an excellent compromise between visibility and compactness. The optic's parallax-free design ensures consistent accuracy, even if your head position shifts.

I did encounter one issue during testing: the RMR mounting plate on my Fusion Firearms XF Pro sits somewhat thick, causing the optic to mount slightly higher than optimal. If co-witnessing with iron sights is essential for you, taller sights might be necessary.

Performance-wise, the G-SRS8 truly shines on the range. The large 8 MOA dot made acquiring targets effortless, especially in close-range defensive drills. After several hundred rounds, the optic consistently held zero, demonstrating robust reliability. Lens clarity remained excellent throughout, with no noticeable distortion or degradation.

Despite its many strengths, the G-SRS8 has a couple of minor drawbacks. It lacks an automatic brightness adjustment feature, requiring manual brightness tweaks when moving between varying lighting conditions. Additionally, the optic doesn't come with a lens cover—something I believe would enhance its overall value.

So, who should consider this optic? Concealed carriers seeking a compact, intuitive optic will find great value here. Competition shooters will appreciate the rapid target acquisition provided by the larger green dot, and shooters with astigmatism will significantly benefit from the STIG-RS system. At just under \$200, the Cyelee Chameleon G-SRS8 is one of the best budget-friendly options available today.

In summary, despite minor limitations like manual brightness adjustment and potential co-witnessing challenges, the Cyelee Chameleon G-SRS8 is a highly recommended green dot sight, providing exceptional value and performance.
