Spring-loaded sights deploy at the push of a button to provide instant backup sighting. Quick Deploy System locks securely and requires a firm, positive press of the button to deploy or retract the sight, so it won’t accidentally activate when bumped—these sights stay where you put them. Minimal profile when folded—only .435” high—with radiused edges and a smoothly curved front surface to prevent snagging on foliage, gear, or clothing. Crossbolt and side bar provide solid attachment to MIL-STD 1913 Picatinny or Weaver-style rail systems. All-aluminum construction is lightweight, yet plenty strong to handle the hard knocks of tactical operations, with a durable, scratch-resistant hardcoat anodized finish for extra surface strength. Set contains the front sight with ears and the two-position rear sight.
