Description
ACM Holosight Clear ABS Cover (551/552)
This is a clear ABS protective cover from ACM for 551 and 552 style holographic sights. Holographic sights have a large flat front window that is easily scratched, chipped or cracked by BB hits and knocks, and a clear cover protects the glass while still allowing you to see through the sight normally.
ACM is a budget brand covering a wide range of airsoft accessories. A simple clear cover is one of the cheapest ways to protect your optic, and many players fit one as soon as they buy a holographic sight replica.
Why fit a protective cover
In airsoft your sight faces the same direction as your opponents, so it is often hit by incoming BBs. Replica holographic sights generally use glass or plastic windows that can crack from a direct hit at close range. A clear ABS cover takes the impact instead, and if it becomes scratched or damaged it can be replaced far more cheaply than the sight itself.
Fitting and use
The cover is designed to fit over the front window of a 551 or 552 style sight. Check that it sits securely and does not touch the lens, and look through the sight to make sure the reticle is still clear. Because it is clear rather than mesh, it does not obscure the view the way some lens protectors can.

Care and maintenance
Clean the cover with a soft damp cloth and mild soapy water; avoid solvents, which can cloud or crack ABS. Replace it if it becomes deeply scratched or cracked, as damage can reduce clarity. Remove it occasionally to clean any dust trapped between the cover and the sight.
