28mm Red Dot Lens Protector – 3DM

3DM polymer lens protector for red dot sights with a 28 mm internal diameter: a clear shield, also known as a sacrificial lens, that stays fitted in front of the optic and protects the glass from BBs and accidental knocks. You aim straight through it, so the red dot stays ready for use throughout the game.

In the field

In airsoft the front lens of a red dot is exposed to direct hits, especially in close-quarters engagements and CQB: a single BB can chip it and put the optic out of action. The protector takes the hit instead of the glass and, if it gets marked, it can be replaced at minimal cost rather than replacing the red dot.
