New U.S. Optics B-Series Rifle Scopes | SHOT 2017

U.S. Optics brought three new rifle scope options to the SHOT Show this year. The new B-Series rifle scopes are packed with quality features that separate high-end glass from ordinary rifle scopes. I was able to talk with U.S. Optics marketing representative Maggie, and she walked me through the specifics on the new B-10, B-17, and B-25 scopes.

The U.S. Optics B-Series rifle scopes have excellent features.

The B-Series rifle scopes receive their name for the highest magnification level they achieve. The B-Series scopes have been specifically designed by U.S. Optics engineers to have shorter and lighter tubes to reduce profile and bulk. The new B-Series scopes have moved the illuminated reticle controls to the outside of the Parallax adjustment knob, with a simple push button control. Holding the button in constantly will turn the illumination off regardless of power level. By moving the illumination controls U.S. Optics has provided easier access while at the same time eliminating the need for an additional knob.

The B-Series scopes place the reticle illumination controls on the Parallax turret.

U.S. Optics B-Series scopes will all come with zero stop technology. Once the zero has been determined, the B-Series scopes have a locking turret ring designed to push down (elevation) or outward (windage) to disengage the adjustment gears. The shooter can then dial the turret back to actual zero without interfering with their turret adjustments. Once the turrets are back to zero, the shooter pulls the turret ring up (elevation) or inward (windage) to re-engage the turret adjustment gears at actual zero. The B-Series turrets are shorter but a little wider to reduce profile without losing easy manipulation.

B-Series turrets are shorter and wider to reduce profile while keeping ease of manipulation.

The B-Series scopes also come with a zero stop function for the elevation turret, to prevent the turrets from going past the determined zero after an adjustment has been made. This is a very nice feature to confidently return the rifle to zero at the end of a day of shooting or hunting. To create a zero stop, the shooter uses a standard screw driver to tighten the silver screw in the middle of the turret top. This will not interfere with the shooter’s ability to make elevation adjustments, but sets a zero stop to avoid going past zero when adjustments are no longer needed.

Interestingly though, the B-Series scopes have a unique tactile indicator for full turret rotations. As the turret is rotated a full 360-degrees, the same zero stop screw rises out of the turret at varying heights to give the shooter a tactile feel for excess elevation. When the screw is flush with the turret, the shooter is back on to true zero.

The Zero Stop screw is in the middle of the elevation turret, and when flush with the turret indicates true zero.

Here the Zero Stop screw is slightly elevated from the turret showing the turret is in the first full rotation above zero.

All of the new U.S. Optics B-Series scopes will have first focal plane (FFP) reticles. The first focal plane reticle is ideal for long distances shooting, as it maintains the hash mark striation or mil-dot values of the reticle regardless of magnification level. Though the reticle becomes larger with higher magnification (somewhat reduces the visual picture in the glass), the shooter can still confidently use hold-overs. Second focal plane reticles magnify without adjusting the reticle, and therefore lose hold-over values.

The B-Series scopes each offer several reticle choices, with the longer range models greatly expanding the shooter’s options. The B-10 offers the GAP Mil; the MOA Scale Type I, or the Horris Vision H425. U.S. Optics places the B-10 as a great selection for shots out to 1000+ yards. The B-17 will provide the GAP Mil; Gen II XR; MGR; IGR; or the Horus Vision H102 reticles. U.S. Optics suggests the B-17 for shots out to 1700+ yards. Finally, the B-25 will allow shooters to choose from the GAP Mil; Gen II XR; Mil Scale MPR; MGR; IGR; PR2; H37; H59; or H102 reticles. For extreme distance shots of 2500+ yards, U.S. Optics recommends the B-25.

Considering the B-Series are set up for Mil-dot adjustments it would be unwise in my opinion to use the MOA reticle option. It is much easier to maintain the same adjustment values from the reticle and turrets, but U.S. Optics give the shooter the option. The highly complex Horris Vision reticles will cost the buyer an additional $300.00 however.

    My Leupold 3x9x40mm with illuminated reticle for under $500 does everything i’ll ever need a magnified optic to do, and for 1/3 the cost.

    • A Berta

      When most people look at these levels of scopes they are long range and or target shooters. For you a 3×9 Looper will work for you. THAT’S GOOD. For some a 99 dollar Barska is all they need. They both work but have different applications. Deer at 200yds vs deer at 1200 yds.

      • Bill

        Or hostage-taker’s eye socket at 90 yards.

  • Gary Kirk

    Do they still make a fixed 10??

    • bmstylee

      It appears the st10 is not there anymore. Which sucks because I wanted one. Settled on a Nightforce NXS. Never thought I would say settled and Nightforce in the same sentence.

      • Gary Kirk

        May have to start looking at Unertyl again..

        • bmstylee

          Schmidt and Bender make a 10x

  • Michael Guerin

    Aaron, the specs for each scope show exit pupil as 2.0 mm. You might want to contact U.S. Optics over that typo and get the correct info. Otherwise, a good report. Thank you.

    • Got it Michael, and thanks for the catch. The brochure U.S. Optics handed out at their booth has all three at 2.0mm. I’ve got the B-17 corrected to 3.0mm as shown on their website.

    I spoke with USO about the MOA reticle (IGR). They told me that with the B-series they made that one with IPHY and not actual MOA. So each click is 1/4 IPHY and each tick mark is 1 IPHY (inch per hundred yards)
