The Firefield Impact Duo Reflex Sight delivers heavy-hitting close quarters performance for MSR rifles and shotguns. Ideal for both target shooting and close- to mid-range hunting scenarios, the Impact Duo features multiple reticles, customizable by the shooter?s preference. The Duo adds a built-in red laser on the side of the sight, increasing target acquisition at close distances and allowing for precision shot placement. Digital switch brightness controls make adjustments quick and easy while an aluminum/polymer construction help with the Impact?s IP55 water resistant rating. Shockproof and with a maximum recoil rating of .308, the sight is powered by a single CR2 battery with 75-9000 hours of battery life. The Impact Duo is parallax corrected and delivers unlimited eye relief, making it the ideal optic for both-eyes-open, close range shooting.Features: Digital switch brightness controls10 daytime brightness settingsIntegrated quick acquisition red laser sightMultiple reticlesParallax corrected optical systemCR2 BatterySpecs: Reticle, Type:4 Pattern- 5 MOA dot, 3 MOA dot with 50 MOA circle, 3 MOA dot with 50 MOA crosshair, 3 MOA dot with 30 MOA circle/crosshairReticle, Color:RedIlluminated (yes/no):YesReticle Brightness Setting:0-10Magnification: 1Objective Lens:31x22Eye Relief:UnlimitedElevation Range of Adjustment:150 MOAWindage Range of Adjustment:150 MOAAdjustment Value:1 MOAParallax Setting:25 ydsFinish/Color:Matte blackBody Material:Aluminum/polymerMaximum Recoil:.308 CaliberIP Rating (waterproof):IP55-water resistantNitrogen Filled:NoShockproof:YesFog Proof:NoLens Coating:AR RedMount Type:Weaver/PicatinnyBattery Type:CR2Battery life, hours:75-9000Battery Voltage, V:3VOperating temperature, F/C:0 to 122/ -17 to 48Length (in/mm):3.46 / 88Width (in/mm):2.04 / 52Height (in/mm):2 / 51Weight, oz:5.6Laser Type:Red, Class IIIALaser Power Output:
