Firefield Impact Reflex Sight for MSR Platforms & Shotguns

The Firefield Impact Reflex Sight for MSR platforms and shotguns delivers rapid target acquisition with both eyes open at close to intermediate distances. Manufactured by Sellmark Corporation, this compact reflex sight weighs just 0.51 lbs and mounts securely to Picatinny rails common on modern rifles and shotguns. The wide-angle lens provides an expansive field of view that keeps shooters aware of their surroundings while presenting an uncluttered sight picture for quick engagements.

Operational flexibility defines this optic's design. The Firefield Impact features multiple reticle options allowing shooters to select the sight picture that best suits their engagement profile. Digital switch brightness controls enable rapid adjustment to ambient light conditions—critical for transitioning between indoor, overcast, and bright outdoor environments. The reflex design presents the reticle against the lens without magnification, eliminating parallax error and enabling fast target tracking during dynamic shooting. Compact dimensions of 7.1 x 1.75 x 7.8 inches position it low in the sight plane, reducing height-over-bore offset and minimizing interference with co-witnessed iron sights or secondary optics.

This sight suits operators, tactical shooters, and hunters running modern sporting rifles or tactical shotguns who prioritize speed over magnification. Law enforcement and defensive-focused shooters benefit from the both-eyes-open sight picture, which maintains target awareness and situational dominance in home defense or duty-weapon configurations. The wide lens also serves shooters with astigmatism better than enclosed tube designs, as the open window reduces internal reflections that can distort reticle clarity.

Reflex sights remain popular across the tactical and hunting communities because they match the speed of instinctive shooting while maintaining optical simplicity. The Firefield Impact's customizable reticles and brightness adjustment make it a versatile choice for shooters who transition between platforms or adapt to changing light conditions during extended range sessions or field work.
