Scope Caps

Scope caps shield the exposed glass at both ends of the tube from rain, blowing grit, and accidental knocks while the rifle is carried or stowed. The popular flip-up style is spring-loaded and hinged so it snaps open with a thumb when a target appears, then closes again to keep the objective lens and the ocular lens clean between strings. Simpler bikini-style covers and pull-on neoprene sleeves do the same job at lower cost, trading a little speed for security.

A scratched or fouled lens robs the scope of the contrast and clarity it was bought for, so caps are cheap insurance for an expensive optic. On the objective end, a flip cap also keeps stray light off the front element and can pair with a sunshade that extends the tube against glare. The main discipline is remembering to open them before settling in, since a closed cap is an easy way to lose a fleeting shot.
