US Optics 5-25x52 GAP .1MRAD B-25 GAP

Reticle Image

This B-25 optic features the GAP MIL Scale reticle. The GAP MIL Scale reticle has both MIL and 1/2 MIL increment lines. It has a total of 9 MILS down and 4 MILS up on the vertical axis and 4 MILS to the left and right on the horizontal axis.

Modern rifle scopes must meet the demands placed upon them in an operational sense, as well as satisfy consumers. It's not always easy to do both, but U.S. Optics has come up with a winner in their new "B" Series, which includes the B-10, B-17, and B-25 scopes.

The B-10 is a medium-range scope, meant to engage targets out to a range of ~1,000 - 1,200 yards. The B-17 is a medium-long range scope, meant to engage targets out to a range of ~1,500 - 1,700 yards. Finally, the B-25 is a long-range scope, meant to engage targets out to a range of ~2,500-yards (and potentially further) in the hands of a capable marksman.

Though the general rule of thumb is 1x magnification power for every 100-yds (approximately) range between the shooter and the target, there are certainly scopes with low-grade lens materials that can make successfully engaging a target at moderate- to long-distance a real challenge. Not so with the B Series. U.S. Optics utilizes premium lenses and materials in the construction of these scopes, sealing them against the elements.

A series with premium features and numerous reticle options, U.S. Optics' B-series scopes are destined to find their way on to precision rifles owned by the most discerning operators and competitors.

The B-25 has the most features and highest magnification of the B Series optics.
