Delta Armory Holo-551 Style Red Dot Sight

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. 

Benefitting from a strong alloy hood protecting the delicate internals, the holographic sight design is often credited with being one of the more robust red dot designs on the market, insulating you against accidental bumps and scrapes, unlike other "open" red dot designs. If you're an aggressive, or dare we say it, clumsy skirmisher, this could save you some anguish! If you're looking for a holographic-style optic for your SMG-5, AR-9 or other compact SMG, this is the one to go for!
