Secure and fast acting cap - Vortex Defender Flip-Cap Lens Cover

I wanted a secure cap to protect my Vortex Viper pst. I ordered the package for a 44mm and hoped the lens’s cap would fit. It did! I like the dope sticker it comes with as well. Only complaint is the cap secures with a tight rubber sleeve and makes the focus ring unobtainable. Once you have it set most of your adjustment will be with the parallax. It flips closed with a confident secure click.
