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.

Optical quality is great, best of any scope I have. Arguably on par or better than Kahles, Night force, etc. MK5 3.16-18 does not hold a candle to it. Low light is good, illumination works well. Eye Relief: It does decrease with increasing magnification. For PRS I would recommend setting up the eye relief for 12-15 power (mid range). Turrets: Wind is good, elevation could use improvements. Torque required is a bit much however I haven't used it much. Zero stop works well, follow the manual. MK5 turrets are better in my opinion. Scope caps click when zeroing, I recommend looking through the optic when drifting to ensure the reticle doesn't adjust. Using 30MOA base and plenty of usable elevation for zeroing at 100yds. Overall very pleased
