FMA flip-up lens cover for scope and torch — Black

FMA flip-up lens cover, sold as a pair — one clear lens and one yellow polycarbonate lens — designed to protect the objective lens of a scope and the glass of a weapon-mounted tactical torch. The cover flips open with a single motion, without moving your hand off the grip, and snaps back shut with a click.

The clear lens keeps the reticle readable even with the cover closed, useful when you want to shield the optic from rain, dust and debris without losing your sight picture. The yellow lens filters light in low-contrast conditions — haze, strong artificial lighting — and can improve target definition at medium range. Both inserts are removable, so the shooter can use the cover purely as mechanical protection, with no optical filter.

The flip-up mechanism represents a trade-off worth understanding: the snap-shut closure keeps the cap firmly in place during transport and reduces the risk of accidental opening, but requires deliberate pressure to open — slightly slower than a spring-loaded quick-release system. Those operating in environments with a high likelihood of dirt and impacts tend to prefer this more secure retention; those prioritising maximum acquisition speed may prefer a spring-loaded flip-up. The black finish integrates with most standard Picatinny rail setups.
