When you carry a pistol for defense, you need a sight that is small, tough, and ready the second you need it. The Holosun HE507K-GR-X2 reflex sight is a top choice for concealed carry. This Compact Pistol Sight is an Open Reflex Sight designed to be fast and reliable. Unlike many other optics, this one shines a bright Green Circle Dot Sight, which many shooters find easier to pick up quickly than red, especially in bright sunlight.

This sight is part of Holosun's trusted line of optics. While some people call it a Holosun Red Dot, this specific model uses a green light source for the reticle. The Holosun HE507K-GR-X2 gives you options with the Multi-Reticle System (MRS). You can switch between a simple 2 MOA dot, a 32 MOA circle, or combine them into a clear circle-dot. The 2 MOA dot is great for precise aiming, and the large 32 MOA circle helps you aim fast at close range.

One of the best parts about the Holosun HE507k is the smart power system. It has Solar Failsafe technology, which means the optic can run on the sun's power, helping to save the battery. The optic also uses Shake Awake technology. This means the sight turns off when it sits still for a time to save battery life. The second you move the gun, the sight turns instantly back on to your last setting. This gives you a very long battery life—up to 50,000 hours at a medium setting. The controls are simple to use. The X2 series also includes Lock Mode, which stops you from accidentally changing your settings while the gun is being carried or handled.

The body of the sight is made from durable 7075 Aluminum, so it is strong enough to handle the rough treatment of being carried every day. This rugged construction is exactly what you need in a defensive optic. If you want a small, feature-rich, and dependable Holosun Green Dot Sight, the HE507K X2 Open Reflex Sight is an excellent choice.
