The Vortex StrikeFire II Red Dot gives you fast target pickup, simple controls, and solid durability without a high price. It fits hunters and shooters who want a bright and clean reticle with both eyes open shooting. The eye box is open and clear, so you do not waste time lining up the dot. The controls sit on the back of the unit so you can adjust settings without breaking your stance. You get ten brightness levels. Eight levels are for daylight, and two are night vision ready. The sight powers back on at the last level used, which saves time in the field. The 4 MOA dot is easy to see and works well at close and mid range. Many shooters like the dot size because it balances speed and accuracy. The 30mm tube uses aluminum alloy that can take recoil. The unit is waterproof and fog-proof, so the weather does not stop your hunt. The lenses have multi-coating for better light use and sharp edges. Unlimited eye relief lets you mount the sight at different positions on your rifle and still shoot comfortably. The StrikeFire II red dot is light enough for long days outdoors and still tough enough for heavy use. You can use the Vortex StrikeFire Red Dot for hogs, deer, home defense, or range fun. It also fits well in setups that require simple, fast dots. The included cantilever mount puts the sight at the right height for AR style rifles. Flip caps protect the glass, and the unit runs on a CR2 battery that is easy to find. If you want a proven dot without gimmicks, the Vortex StrikeFire II 4moa red/green dot line makes sense. EuroOptic carries a solid range of Vortex red dots, so you can pick the setup that works best for your rifle.
