US Optics ER-25 5-25x Rifle Scope – Features and Dimensions
Crystal clear images, impossibly long distance shots and rapid target acquisition might be the dream of every shooter. With the ER-25 5-25X rifle scope, this dream becomes a definite reality. With USO’s ER-25 a 2000 yard shot, that might otherwise seem impossible, becomes achievable.
The 5-25X magnification potential of the 58mm objective lens ensures that the images even at a distance of 2000 yards are high on clarity and resolution. The lens is placed in front of the TPAL or the Turret Parallax Adjustment Locator. With the ER-25 on its highest power setting and the illuminated reticle at your disposal, acquiring targets at great distances in challenging weather and light conditions becomes fairly simple. The EREK (Erector Repositioning Elevation Knob) system with its umpteen options ensures the highest level of elevation travel adjustment. From the scope body to the objective housing, all components are built with 6061-T6 aircraft aluminum and coated with Matte Black Type III hard anodizing.
Base Model Specifications
- Color: Matte Black Type III Hard Anodizing
- Knob Elevation: EREK 1/10 MIL 110 Click
EREK= Erector Repositioning Elevation Knob. This knob has set itself into a new class of knobs in the industry.
The large diameter and the low height gives it a very uniques look. With 110 clicks per one revolution, it allows for a large amount of travel in a single turn. With 1/10 MIL click values you will get a total of 11 MIL's per one revolution.
The center rough zeroing screw allows the user to set where in the knob's travel the beginning and ending is, so you can adjust where the zero is located, or how many clicks below zero is set.
After the zero is set, the user must replace the top washer with the one provided with the tool kit, this will ensure an environmentally sealed scope.
- Knob Windage: US#3 1/10 MIL 100 Click (RIGHT)
The U.S. #3 knob is a little larger than the #1 knob and has 100 clicks per one revolution. In 1/10 MIL this knob will allow 10 MIL's per one revolution. Unlike the U.S.#1, this knob does not have the option of a screw on protective cover.
- Reticle Lighting: Digital Push Button (Red)
U.S. Optics has gone above and beyond the other manufacturers with our digital push button rheostat. This feature utilizes a three button design that allows the user to turn off/on and up/down. This unit allows the user to set a needed intensity, then turn off the unit and then back on to the prior setting. There is an automatic power shut off after 1 hour if no buttons are pushed. Battery life is 100 hours on the highest setting. A 2032 coin battery powers the unit.
- Reticle: Mil Scale GAP
Designed in conjunction with George from GA Precision, this MIL based reticle offers full MIL as well as ½MIL increments. A total of 9 MIL's from the center down on the verticle axis, and 4 MIL's left and right of center on the horizontal axis.
- Eyepiece Housing: Lo Profile - Rapid Focus
Due to its smaller diameter the Lo-Profile Eyepiece allows the scope to be mounted lower that the standard eyepiece. This improvement comes with no structural sacrifice.
