Guerilla Tactical Holo-551 Style Red Dot Sight

Guerilla Tactical
Code: GO-KOL-05-BLK
  • Aluminium construction
  • Compact Holographic style red/green dot
  • Integrated 20mm Picatinny rail mount

If you like the styling of real steel holographic sights, the Guerilla Tactical 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!

Full description


The more compact variant of the Holo-552, the Guerilla Tactical Holo-551 Style Red Dot Sight replicates the classic holographic sight design we all know well from video games, movies and TV. Offering a multi-functional reticle providing two dots for precise shooting with an outer ring for rapid close-ranged work, the Holo-551 allows you to engage targets at close range very quickly using only the outer ring, or take more precise long-range shots using the central dot, provided you zeroed your sight before the game!

The Holo-551s' smaller form factor requires less rail space to mount than the much bigger Holo-552, making it perfect for short-barrelled setups with limited rail space and more slender platforms. Other than the change in battery type, the Holo-551 provides the same functionality as the 552 variant, including its rear-facing controls, integral 20mm Picatinny rail mount and multiple brightness levels with the choice of red or green illumination. 

Zero adjustment is provided by a pair of adjustment screws on the right side of the optic, recessed into its alloy protective hood. The front screw controls left-right adjustment (windage) and the rearmost screw provides elevation adjustment. The controls are located on the rear of the optic, with the "NV" button above the arrow keys functioning to change the reticle colour from Red to Green and the up and down arrow buttons allowing for brightness adjustment, with 5 brightness settings for both colour options. 

The Holo-552 Style Red Dot Sight features an alloy protective hood surrounding the sight's delicate lenses and electronics, giving it some additional drop protection to cover you for skirmish clumsiness. The battery compartment is positioned at the front and designed for four LR44 button cells. To open the battery compartment, all you need to do is lift the throw lever on the top of the sight and the battery cover can be lifted free. 

Mounting the Holo-551 is just as easy as with its bigger brother. Simply loosen off the thumb screw on the left side of the mount, position your Holo-551 where you like it and tighten it down, either by hand or using a flathead screwdriver. While the Holo style of red dot sight is one of the more robust designs used for Airsoft, we always recommend using a Lens Protector to keep the lens safe from incoming BBs. 

If you like the looks of holographic sights but run a compact primary with little rail space to spare, the Guerilla Tactical Holo-551 Style Red Dot Sight is the one to go for. A strong design with a unique multi-functional reticle and military-style looks, this red dot sight is perfect for Milsim builds!
