• Aluminium construction
• Compact Holographic style red/green dot
• Integrated 20mm Picatinny rail mount
If you like the styling of real steel holographic sights, the Delta Armory Holo-551 Style Red Dot Sight is one to watch. Patterned after the real steel 551 holographic sight, the Holo-551 is the shorter alternative to the Holo-552, ideal for compact platforms with limited rail space. Boasting an integral 20mm Picatinny rail mount, red and green reticle illumination with 5 brightness levels for each colour, the Holo-551 provides the same superb utility as the Holo-552 without wasting space on your primary.
