Holosun - Open Pistol Collimator HE508T X2 with Picatinny Rail Mount - Red Reticle - MRS - Solar Panel

The Holosun 508T X2 is an open-sight pistol red dot sight that combines advanced electronics with durability thanks to its titanium housing. Minimized parallax allows for quick, instinctive aiming, which significantly reduces the time to shot during dynamic shooting.

Reliable power supply and Shake Awake technology

The device utilizes a dual power source thanks to Solar FailSafe technology. The built-in solar cell supports the CR1632 battery, and in bright light conditions, it allows the sight to operate without drawing power from the battery. This means the user doesn’t have to worry about the risk of needing to replace the power source in the field.

The Shake Awake system is responsible for energy savings. This technology puts the LED to sleep during inactivity and wakes the device upon detecting the slightest movement, restoring the last-used operating mode. This way, you don’t have to remember to turn the collimator on and off during training. This solution allows for an operating time of up to 50,000 hours on a single battery.

MRS System – Three Reticles for Accuracy at Any Distance

The HE508T-X2-RD red dot sight offers three reticles thanks to the Multi-Reticle System. Without the need to re-zero the device, you can choose between three configurations: a 2 MOA dot, a 32 MOA circle, and a dot + circle combination, ensuring high effectiveness in dynamic shooting.

The red light emission at a wavelength of 650 nm is adjustable across 12 brightness modes. Eight levels are designed for daytime use, while four additional levels allow for effective use with night vision devices.

High durability thanks to the titanium housing

The use of titanium as the material for the red dot sight housing has enabled exceptional durability. Titanium is characterized by significantly higher hardness and resistance to mechanical damage, while maintaining the device’s low weight.

The design has been tested for resistance to vibrations and shocks of up to 5000 G, ensuring trouble-free operation on high-recoil pistol actions. The sight meets the IP67 waterproof rating, enhancing reliability in harsh weather conditions.

Low-profile Picatinny mount included

The low-profile Holosun mount allows the Holosun 508T red dot sight to be mounted on standard Picatinny rails. Thanks to its low profile, the mount ensures proper optical alignment.

The use of a mount with a height of just 10 mm allows for a natural shooting stance while keeping the sight line as close to the barrel as possible. This solution facilitates instinctive alignment of the reticle and improves the balance of the entire setup. The design ensures a perfect fit with the RMR footprint, maintaining the sight’s stability even under intense recoil.

The contact surface with the red dot sight and the Picatinny rail is machined using CNC milling, eliminating play—which is essential for maintaining zero. Mounting on the rail is done with a single Torx screw, which ensures high clamping force and a secure connection while maintaining ease of use.
