Strike Systems Advanced 552 Collimator — Black

The Strike Systems Advanced 552 is an open red dot sight for airsoft with a selectable red or green reticle, designed for shooters who need a reliable aiming solution on replicas with a Picatinny or Weaver rail. The metal and hard plastic body keeps weight down to 300 grams, balancing durability with practical handling in the field.

The dot is available in two interchangeable colours and brightness is adjusted via a control panel facing the shooter, reachable without changing your grip. This lets you adapt the reticle to lighting conditions — from a dim indoor environment to full sunlight — without breaking visual contact with the field. The trade-off is typical of sights in this price range: windage and elevation adjustment is done manually with a screw, which is effective and precise but requires a tool and some time compared to the field-adjustable clicks found on higher-end models.

Power comes from 2 AAA batteries housed in a compartment with a lever-release cover that allows quick replacement even during a game. The 21 mm screw-mount base is compatible with standard Picatinny and Weaver rails: installation is direct, with no adapters needed.
