Helpful Review

The Holosun 510C is a fantastic red dot sight that pairs perfectly with your B&T GHM9. The glass quality is excellent, offering a nearly imperceptible blueish hue that doesn’t interfere with clarity.
The coating on the glass effectively blocks red laser light, ensuring a crisp view without distortion.
The dot quality is near perfect, with a clear red dot and the ability to switch to a 68 MOA segmented circle, providing versatility for different shooting scenarios. This flexibility is ideal for both precision shots and close-range engagements.
In terms of parallax, the 510C performs exceptionally well. There is virtually no perceptible parallax, which means the dot remains on the target, even when your head or eye position shifts.
This is a huge advantage for dynamic shooting, especially in fast-paced situations. The battery life is impressive, offering up to 50,000 hours with the dot-only setting and 20,000 hours with the segmented circle.
The “shake to wake” feature is also a great addition, ensuring the sight activates as soon as you pick up the firearm, making it always ready when you need it.
The 510C has a large viewing window, which enhances situational awareness. The metal casing is thin and unobtrusive, contributing to a clean and wide field of view.
There is no visible battery compartment, which helps maintain the sight’s sleek look and ensures no visual obstruction when aiming.
The overall construction feels solid, and while the quick-detach mechanism could be vulnerable if dropped while halfway open, it is built to withstand regular mounting and dismounting without issue.
The recessed LED emitter further protects the sight, making it more durable in rugged environments.
The Holosun 510C offers excellent performance for its price. It provides a large field of view, a clear dot, long battery life, and solid construction, making it a great choice for your B&T GHM9. The added convenience of the shake-to-wake feature ensures that it’s always ready to go when you are.
