Vortex Optics Defender 翻蓋式鏡頭蓋，物鏡 O-50 瞄準鏡配件

Installed this cap on my rifle scope and it fit tight without any wobble, the snap flat spring mechanism is a huge upgrade over the loose rubber caps I used before. Feels solid enough that I’m not worried about it cracking in the field.

The rubberized exterior gives a solid grip even in wet conditions, and it popped onto my scope without any struggle. I've accidentally knocked it a few times already and there isn't a single scratch.

The spring snaps flat with a satisfying click every time, and the fit on my 50mm objective is snug enough that I’m not worried about it popping off in the field. It feels tougher than the plastic caps I’ve gone through before, so this really might be the last one I buy.
