While iron sights have always been able to get people on target, they're often considered less precise than other optics options, as well as getting in the way of seeing the target at extended range. The Ultradyne C4 Offset Sights fix this problem by providing an innovative sight picture based on the company's Dynalign technology. This Ultradyne C4 rear sight provides AR-15 shooters with a rear aperture that, when combined with a compatible front sight, offers what the company calls a "circle-within-circle" sight picture, allowing users to simultaneously observe a target while dialing-in their iron optics.

• Mounts to any MIL-STL 1913 Picatinny rail
• Made from combination of 4140 chrome-moly steel and 7075 aluminum
• Weight: 2.5 ounces
• Treated with salt-bath nitride finish and anodized-black finish

Each Ultradyne C4 Offset Rear Sight is built with a folding mechanism that allows the unit to lie flat on a receiver rail until needed. The unit is machined entirely in the USA and is offset 45 degrees to the right side, allowing users to mount these sights in conjunction with a magnified optic for a total sighting system.
