The FastFire E establishes a new standard in red dots with a 60,000-hour battery life and ultra-rugged monolithic machined aluminum housing. The waterproof, shockproof, and fogproof closed emitter construction protects the emitter from environmental damage and obstructions like snow or mud and is ready for any competition, duty, or hunting setup.  Combined with a 3.5-MOA “always on” aiming dot, means the FastFire E maintains reliable operational readiness for any scenario. The 3.5-MOA dot with an “always on” feature ensures instant readiness, and its aspherical lenses provide a distortion-free, glare-resistant view, enhanced by eight brightness settings (two night vision compatible) and choice of a red (BO300266) or green dot (BO300267). Featuring one of the widest windows, for an industry-leading field of view, and 1X magnification that enables fast, both-eyes-open shooting. Fully adjustable windage and elevation with a 100-MOA range and an Aimpoint ACRO® footprint ensure precise, secure mounting.
