Burris FastFire E Features The Burris FastFire E is built around the ACRO P-2 mounting footprint allowing it to mount directly to dedicated ACRO slide cuts as well as aftermarket ACRO mounting plates for a wide range of optic-ready pistols and rifles. Its 3.5 MOA green dot reticle offers 100 MOA of both windage and elevation adjustment giving shooters ample room to zero the sight precisely to their point of impact. With 8 day and 2 night brightness settings plus automatic brightness adjustment and an auto shutoff feature the FastFire E adapts continuously to changing light conditions while conserving battery power when not in use. The sight s aluminum housing is shockproof and waterproof standing up to the recoil and environmental exposure of duty and competition use and at just 2.45 oz it adds minimal weight to a pistol slide or rifle mount. A single CR2032 battery delivers up to 60 000 hours of runtime meaning the FastFire E can be mounted and largely forgotten between battery changes. Burris includes a T10 adjustment tool lens cloth and user guide with every unit giving shooters everything needed to mount zero and maintain the sight right out of the box.
