The HE507C-GR X2 collimator has a body made of 7075 aluminum, using a precision milling method. This makes the device lightweight, weighing just 42 grams, yet durable. The collimator is mounted on a standard RMR base, making it easy to install on small arms. The X2 version uses a horizontal button layout, which has won praise from most users, as well as Lock Mode, which protects against accidental changes in settings. The device meets the high standards of IP67 protection, which means it is resistant to weather conditions and short-term immersion in water. The body of the collimator is covered with a layer of hard-anodized aluminum, which increases resistance to scratches and abrasion.

ACSS Vulcan reticle pistol collimator

The Primary Arms by Holosun HE507C-X2 pistol collimator uses the innovative ACSS Vulcan targeting system. Instead of the traditional red dot, the ACSS Vulcan system uses an inverted V-shaped mark that allows quick and precise aiming at longer distances. In addition to this, the system is supported by a large off-swivel circle that helps to quickly position the chevron in the center of the target. If the aiming point is lost, the edges of the lens display the outline of the circle, which helps to apply corrections and return to the chosen target. The collimator’s lenses are coated with multi-layer anti-reflective coatings, ensuring a clear and sharp image without parallax error. The device is also resistant to shock, weapon recoil and harsh weather conditions.
