What should be avoided when cleaning the optics of the M16A3/M4A1?

The emphasis when cleaning the optics of the M16A3/M4A1 is on the importance of avoiding excessive pressure due to the potential damage it can cause. Applying too much force can scratch or distort the lens surface, leading to decreased optical clarity and impairing target acquisition. Keeping the optics in good condition is essential for maintaining accuracy and performance, so handling them with care is crucial.

Selecting appropriate cleaning methods and materials is also important, such as using a microfiber cloth which is designed not to scratch surfaces, and using specialized optic cleaners that are safe for lens coatings. Cleaning when the optic is dry can also lead to particles being dragged across the lens, potentially causing scratches. Therefore, moderating the pressure applied during cleaning is a critical aspect of maintaining the integrity of the optic equipment.
