The larger objective of the Trijicon RX30 Reflex allows the user to move the firearm freely and remain on target at multiple shooting angles when surveying an area. Featuring a large 42mm clear aperture lens, advanced multi-layer coated lenses and a larger +/- 30 MOA (one click per inch at 100 yards). With no batteries to rely on, this dual-illuminated sight features both fluorescent fiber optics and a tritium lamp for a clearly defined aiming point in any light condition. Cast of A356-T6 aluminum with hard coat anodizing, per MIL-A-8625, the RX30 Reflex measures 4.87 inches long by 2.07 inches wide by 2.22 inches high and weighs only 12.5 ounces. It is also tested per MIL-ST-810F to stand up to and perform under the most extreme environmental conditions. The sight is compatible with all existing Trijicon Reflex Mounts (except the RX10).
