For outstanding performance plus rugged construction, a BarskaA(R) 2nd Generation Sniper 4-16x50mm Rifle Scope provides high-resolution sighting of distant targets. The multi-coated lenses provide perfect clarity and enhanced light transmission for distant sighting of still and moving objects. The illuminated mil-dot dual color reticle includes green (ideal for daylight targeting) and red (for low light situations) with 5 different brightness settings, giving you the ability to adjust the brightness to match the environment. Impact-resistant construction ensures that the lenses stay secure after repeated firing and will maintain zero if bumped or dropped. Target-style windage and elevation knobs easily make 1/8 MOA click adjustments. Every Sniper Series scope is dry nitrogen-purged and o-ring sealed, which will prevent fogging inside the scope and offers waterproof protection. The Sniper scopes also come with a protective scope cap and a set of rings.
