Vortex Optics Defender フリップキャップ 対物40 スコープアクセサリー

The rubber is thick enough to seal out dust, and the flip cap opens smoothly without much effort. I've been using it on my scope for a few range trips now, and it stays put even with recoil. Exactly what I needed for the objective.

Snapped right onto my 40mm objective lens with a satisfying click and holds tight. The flip cap feels sturdy enough to handle bumps in the field without popping open unexpectedly.

I was a little worried about the fit on my 40mm objective, but the Defender clicks right into place and stays put. It flips open easily even with gloves on, which is perfect for cold-weather hunts.
