This is a replacement rubber eyecup for Pulsar Trail and Apex thermal riflescopes. The eyecup is meant to provide the correct eye relief for Apex and Trail series to prevent splashback from the display at night. It is compatible with all current and older model Apex and Trail series, including the Trail LRF and Trail 2 LRF. The Core RXQ30V will also be compatible with this eyecup.
