The Thrive HD Reflex Sight is built on the Trijicon RMR pattern, a mounting footprint shared across pistol slides, rifle mounts and shotgun rails. That makes one 3 MOA Red Dot usable across several guns, with the same sight picture on each. The housing is 7075-T6 aluminum, with shockproof and waterproof construction and a working range from -4AdegF to 158AdegF. Multi-coated optics carry light through to the dot, and the sight weighs 1.48oz with the battery installed and before a mount, which keeps the finished setup light. A dot that transfers between guns becomes the constant in a setup that changes around it, the same 3 MOA aiming point on whichever host the day calls for. Backed by the ZeroTech Triple-A Lifetime Warranty, it is a sight worth building around.
