The 1” tube Optika5 2-10x42 is available in 2 configurations, with or without side mounted adjustable parallax (PA). Both models feature MeoBright lens coatings for optimal light transmission and MeoDrop hydrophobic water repellant coating. Fixed parallax 2-10x42s are set parallax free at 100 yards, while the parallax adjustable (PA) version has side mounted adjustable parallax from 10yds to infinity for fine-tuned focus at any range. Second focal plane reticle options include Z-Plex and MOA based Z-Plus. ¼ MOA adjustments are standard on both models.
