The body of the sight is made of 6061-T6 aluminum, using precision milling for light weight and strength. The weight of the sight with high mount is only 138 g.\u003c\/p\u003e\n\n\u003cp\u003eThanks to the motion sensor, the Holosun HS503-G ACSS CQB achieves an impressive service life of up to 50,000 hours. The unit automatically turns off the LED when there is no movement activity, going into sleep mode. Simply moving the weapon is enough to re-activate the aiming mark. The battery is mounted on the side, under a nut on the right side of the body. This design makes it possible to replace the battery without removing the collimator from the weapon.\u003c\/p\u003e\n\n\u003cp\u003eThe sight uses lenses covered with multi-layer anti-reflective coatings, which provide a clear and sharp image and high light transmission. The device is equipped with a control system and diode resistant to shock (1000 G) and weather conditions, which guarantees stable operation on any weapon.\u003c\/p\u003e\n\n\u003cp\u003eThe ACSS CQB sighting reticle's chevron, dot scale and horseshoe-shaped ring allows for effective fire at both short and longer ranges (up to 600 yards) using a range of popular calibers such

dedicated mainly to carbines, and a low mount recommended for shotguns and rifles of the AK family, which allows you to achieve the optimal sight height over the barrel.\u003c\/p\u003e\n\n\u003cdiv
