Winged eyecups make it easy to block out light and get a sharp, clear image through your Swarovski spotting scopes, ensuring that you have the ability to spot game, wildlife or targets with ease. If your spotting-scope eyecup has been lost or damaged, grab a replacement that's made at the same factory as the old one. These OEM replacements ensure an easy fit and meet the same quality requirements as every Swarovski product. Mfg: Swarovski
