The ER 2.5-10x42 Riflescope from Leica features an outstanding optical design and reliable internal mechanics. This rugged, yet extremely refined, sighting solution is well suited for hunting or precision shooting.
Combining a magnification range of 2.5-10x with a 42mm objective offers excellent versatility that's optimized for twilight performance. Leica's legendary optical genius adds cutting edge technology to this already high performance optic; precision ground lenses with AquaDura coatings produce an extremely crisp and well-detailed sight picture.
This ER 2.5-10x42 is configured with a 30mm tube, a matte black finish, 1/4 MOA adjustments, and Leica's 4A reticle in the second focal plane.
A mounting base and rings are used to attach a riflescope to a firearm. A comfortable sight picture is contingent upon the height of the rings. A comfortable cheek-weld is the result of properly positioning the scope over the receiver. Mounting the scope close to the receiver is preferable, yet scopes with larger objectives need higher rings so the front bell can clear the barrel. It should be noted that in many mounting applications, a professional gunsmith's skills will be needed for proper installation.
Nitrogen-filled to prevent fogging
1/4 MOA tactile click-stop W&E adjustments
AquaDura lens coating: water rolls off lenses, dirt is easily removed
4A Reticle in the Second Focal Plane
Leica's 4A reticle features three long thin posts at 3, 6, and 9 o'clock. A single stadia at 12 o'clock intersects with cross hairs at dead-center.
This reticle is positioned in the rear or second focal plane; it does not change dimensions when the scope's magnification is dialed up or down.
