Based upon the 551 optic from EOTech, with all the same features at a more affordable price. The 551 is the shorter, more compact model in the 55x range measuring only 105mm long and 62mm high.
The unit is powered by x4 LR44 batteries (not included but available here), which are easily accessible through the front mounted battery compartment. The lid is held in place with a clever locking lever.
The mount base is made from a heavyweight metal, as is the lens hood and throw levers.
The throw levers allow rapid attachment and removal of the scope from 20mm rail systems with no tools.
The scope sports fog proof internal optics and an illuminated reticle as shown in the picture.
The centre NV button changes the reticle colour between red and green.
This 551 model features two power switches. Press the left button from off to turn the unit on with the automatic brightness mode. Press the right button from off to power on in manual brightness mode. The left and right buttons then feature as up and down brightness settings.
Metal protective lens hood is removable with x3 allen screws
Easy assembly on your 20mm scope rail.
Fits virtually all AEGs with a 20mm rail mount.
Both horizontal and vertical adjustments for zeroing the reticle are located on the right side of the unit.
Reticle flashes when low on power, and the unit shuts off after 2 hours automatically.
Another high quality optic as we have come to expect from Strike.
