Burris FastFire E 3.5 MOA Red Dot sight (SKU: 300266) is a compact reflex sight with a fully enclosed emitter, designed for installation on pistols, carbines and shotguns. Its monolithic housing, machined from 7075 aluminium, provides high resistance to recoil, impacts and demanding operating conditions. The enclosed construction protects the emitter against water, mud, snow and other debris.
The 3.5 MOA red aiming dot allows rapid target acquisition, while the 1x magnification supports comfortable both-eyes-open aiming. The sight provides eight daylight brightness settings and two settings compatible with night-vision equipment. The Always-On mode keeps the sight ready for use, while a CR2032 battery provides up to 60,000 hours of operation at brightness setting 5.
Aspherical lenses provide a clear sight picture with reduced distortion and glare, while the wide 22 × 17mm viewing window makes the aiming dot easier to acquire. The side-mounted battery compartment allows the battery to be replaced without removing the sight or losing zero. The FastFire E uses the ACRO P-2 mounting standard and is compatible with dedicated mounting plates, adapters and slide cuts.
