Hs507comp Competition Reticle Reflex Sight - Hs507comp Red Competition Reticle System Reflex Sight
Holosun Ronin HS507COMP-RD Reflex Red Dot Sight 1x1.1x0.87 2 MOA Dot 32 MOA Circle Reticle Black
The Holosun 507COMP features an oversized window designed for competition and fast target transitions. The multi-reticle system offers 2 MOA dot, 8 MOA ring, 20 MOA ring, and 32 MOA ring options that can be combined for different engagement styles. The large viewing window maintains peripheral awareness during recoil and rapid transitions while still allowing precise aiming at distance.
Built with a 7075-T6 aluminum housing, the 507COMP handles recoil from platforms ranging from PCCs to 12-gauge shotguns. The side-loading battery tray allows CR1632 changes without removing the optic or losing zero. Lock mode prevents accidental brightness or reticle changes during use.
The 507COMP has found a following across competition, home defense, and tactical applications where a wide field of view and fast target acquisition matter more than compact form factor.
