The Crossfire II 4?16x50 AO pairs versatile 4?16x magnification with a large 50 mm objective and fully multi-coated glass for better low-light performance. Its Dead-Hold BDC duplex reticle sits on the second focal plane, giving consistent aiming references at the top magnification. The adjustable-objective (AO) front parallax focuses down to close ranges, while capped, resettable turrets provide 1/4-MOA clicks. Built on a one-piece aluminum tube with a matte anodized finish, it?s sealed against the elements for water- and fog-proof performance.
