Aimpoint ACO – the sturdy and efficient red dot sight optimized for your Stribog SP9A3.

My Experience 

The Holosun HS510C was an absolute joy to use on my Stribog SP9A3. The dual power source was particularly handy when I was out in the field for extended periods. However, the absence of a green reticle and the heftiness of the unit did take a toll on the overall experience.

Aluminum Housing: Crafted from high-quality aluminum, the Spitfire is both lightweight and extremely durable, built to withstand harsh shooting conditions.

Battery Powered: The Spitfire uses a common CR 2032 battery for power, offering longevity and the convenience of easy replacement when needed.

What could be better: Despite its many strengths, the Vortex Optics Spitfire could be slightly smaller and lighter to better suit lightweight fighting rifle setups. Additionally, clearer instructions or markings to prevent backward installation would be a helpful addition.

When paired with my Stribog SP9A3, the Vortex Optics Spitfire has truly shown its prowess. The DRT MOA reticle has provided instant alignment with my target, ensuring fast and accurate shots at close to medium ranges.
