The Nikko Stirling Mountmaster Silver Crown 4-12x40 Rifle Scope is a precision optic designed for discerning shooters. Whether you’re an experienced hunter or a target enthusiast, this scope delivers exceptional performance and reliability.
Key Features:
Crystal-Clear Optics: The multicoated lenses ensure optimal light transmission, resulting in sharp, vivid images even in challenging lighting conditions. Whether you’re tracking game at dawn or lining up your shot during golden hour, the clarity remains unmatched.
Robust Construction: Crafted with a 1-inch matte black alloy body tube, the Mountmaster Silver Crown is built to withstand the rigors of the field. It’s shockproof, so recoil won’t faze it, and it’s also fogproof—no matter the weather, your view stays crystal clear.
HMD Reticle: The Half Mil-Dot (HMD) reticles provide precise holdover points for both elevation and windage adjustments. Whether you’re compensating for bullet drop or accounting for crosswinds, these reticles enhance your accuracy.
Fast Eyefocus: Quickly acquire your target with the fast eyefocus feature. No more squinting or adjusting—just crisp, clear sight pictures.
1/4 MOA Adjustments: Fine-tune your shots with 1/4 MOA adjustments. Each click corresponds to 7mm at 100 meters, allowing you to dial in your zero precisely.
Waterproof and Nitrogen Filled: The Mountmaster Silver Crown is waterproof, making it ideal for wet environments. Rain or shine, your scope remains reliable. Additionally, it’s nitrogen filled, ensuring it stays fog-free even in extreme conditions.
Versatile Mounts Included: As a bonus, we’ve included free 9-11mm dovetail mounts with your purchase. Mounting your scope has never been easier.
