Integrated low-profile sight

Abstract

Methods and systems are provided for an integrated low-profile reflex sight for a firearm. In one example, a system for a sight includes a housing including a collimating lens positioned before a front lens and an illumination assembly projecting a reticle on the collimating lens. A plurality of trajectory adjustment elements are coupled to the illumination assembly and a single side of the housing. The housing is shaped such that a slide of a firearm coupled to the sight may be removed without removing the sight from the slide, and a reticle of the sight and iron sights of the firearm may be co-witnessed.
