Description
Competition-ready precision meets a massive viewing window in this Holosun competition green dot with fully customizable CRS reticle options.
Finding your dot shouldn’t cost you precious time on the clock. The Holosun 507Comp-GR competition green dot sight delivers an exceptionally large 1.1″ x 0.87″ objective lens that makes target transitions effortless, while its Competition Reticle System puts eight different reticle configurations at your fingertips. Whether you’re running USPSA stages or training for duty applications, the combination of a generous sight picture and Holosun’s proven 540nm green Super LED technology ensures you’ll acquire targets faster while maintaining the precision needed for accurate shot placement.
Key Features
- Competition Reticle System (CRS): Eight user-selectable reticle configurations combining a 2 MOA dot with 8 MOA, 20 MOA, and 32 MOA circles for customized aiming solutions
- Super Large Viewing Window: 1.1″ x 0.87″ objective lens provides bigger viewing area than standard pistol red dots for faster dot acquisition
- Green Super LED Technology: 540nm wavelength optimized for human eye sensitivity with better efficiency of standard LEDs, offering improved visibility and potential battery savings
- Extended Battery Performance: Up to 50,000 hours of battery life at setting 6 using a single CR1632 battery with a convenient side-loading tray for battery changes without removing the optic
Important Compatibility Notes
- Uses Trijicon RMR/SRO standard footprint for direct mounting to most optics-ready pistols
- Designed for full-size handgun slides
- Some pistol models with proprietary mounting systems may require adapter plates (such as certain SIG P320 variants, Springfield Hellcat, or specific CZ models)
- Not recommended for compact/slim slides under 0.9 inches wide (consider Holosun 407K or 507K series instead)
Why We Carry It
The 507Comp-GR represents Holosun’s first purpose-built competition optic, designed specifically to compete against premium options like the Trijicon SRO and Leupold DeltaPoint Pro at a substantially lower price point. Multiple users with astigmatism report that the green reticle appears noticeably crisper and clearer than red dots, making this an excellent choice for shooters who struggle with reticle bloom. The CRS system offers unprecedented flexibility, allowing precise target framing for both competition and training applications.
Frequently Asked Questions
How does the green reticle help with astigmatism compared to red?
Many shooters with astigmatism report that green reticles appear crisper and less blurry than red dots. The 540nm wavelength of Holosun’s Super Green LED matches the peak sensitivity of the human eye. However, astigmatism affects everyone differently, so testing with corrective lenses at different brightness settings is recommended.
Which reticle configuration works best for competition shooting?
Most competitive shooters prefer either the 2 MOA dot alone for precision, or the 2 MOA dot combined with the 20 MOA or 32 MOA circle for faster target acquisition. The 20 MOA circle is particularly popular as it provides a visible tracking reference during recoil while remaining small enough for precise target framing. You can cycle through all eight configurations by holding the minus button for three seconds to find your preference.
Will this fit my optics-ready pistol without an adapter plate?
The 507Comp uses the Trijicon RMR footprint, the most common mounting standard for pistol red dots. It will directly mount to most optics-ready Glock MOS, SIG P320 with RMR cuts, CZ P-10 OR, Walther PDP, Springfield Echelon, and similar platforms. Always check your pistol’s manual.
