What Footprint is the Holosun 507K? Understanding the Mounting System
The Holosun 507K is known for its versatility, but understanding its footprint is crucial for choosing the right mounting solution for your firearm. The 507K uses a proprietary footprint, meaning it doesn't directly share mounting patterns with other popular red dot sights like Trijicon RMR or Leupold DeltaPoint Pro. This is a key distinction. While some manufacturers offer adapter plates, it's not a universal fit.
Let's break down what this means and address some common questions:
What is a "Footprint" in Red Dot Sights?
In the context of red dot sights, the "footprint" refers to the pattern of mounting holes and the overall dimensions of the sight's base. This determines which mounting plates or direct mounting systems are compatible. A specific footprint ensures a secure and accurate fit. The Holosun 507K's unique footprint requires mounts specifically designed for it.
Does the Holosun 507K use the same footprint as the RMR?
No. The Holosun 507K does not use the same footprint as the Trijicon RMR, despite some superficial similarities. Attempting to use an RMR mount with a 507K will likely result in an improper fit and potentially damage your firearm or the optic itself.
Are there adapter plates for the Holosun 507K?
Yes, several manufacturers produce adapter plates allowing you to mount the Holosun 507K on slides designed for other footprints, most commonly the Trijicon RMR. However, using an adapter plate adds height to the optic, potentially affecting your sight picture and co-witness capabilities. It's important to carefully consider this trade-off before opting for an adapter plate. Always check the specific dimensions and compatibility of the adapter plate with both your 507K and firearm before purchasing.
What are the dimensions of the Holosun 507K footprint?
While exact dimensions aren't readily available in a single, standardized format (and often vary slightly based on manufacturing tolerances), the key takeaway is that it is not directly interchangeable with other popular footprints like the RMR. Consult the manufacturer's specifications or a reputable retailer for precise measurements if you require them for a custom mounting project.
How do I find the correct mount for my Holosun 507K?
The best approach is to start with your firearm's manufacturer. Many manufacturers offer specific mounting solutions for the 507K on their compatible pistols. If not, reputable optic retailers and gunsmiths can help you choose a compatible mount based on your specific firearm model and desired features. Always double-check compatibility before purchasing.
Choosing the right mount for your Holosun 507K is crucial for optimal performance and safety. Understanding its proprietary footprint and the availability of adapter plates will help you make an informed decision. Always prioritize safety and compatibility to avoid damaging your equipment or firearm.
