Vortex Crossfire II are the entry level of hunting rifle scopes, which come for an affordable price and nice build quality. This is already the second generation of Crossfire rifle scopes, where they made some improvement like the new resettable MOA turrets on all models from this series. Except for the 1x24 Muzzleloader rifle scope, all other in this series are variable magnification rifle scopes with 3 or 4 times zoom factor.
All lenses in those rifle scopes are full-multi coated to improve the light transmission, contrast, and resolution of the image. The turrets on all models are capped for more protection, and the whole main tube is made from a single piece aluminum, which is hard coat anodized. In this series are 1-inch models and 30-millimeter models.
The reticle is placed in the second focal plane, so it has the same dimensions at all magnifications and is non-illuminated. The smaller magnification rifle scopes have fixed parallax on 100 yards (91 meters), where the big magnification models have an AO (Adjustable Objective) to focus on targets on different distances. All rifle scopes have a fast focus eyepiece for easy focusing of the reticle. The whole housing is filled with nitrogen gas to prevent internal fogging on cold days. The warranty on these rifle scopes is 10 years.
