Night Fision Optics Ready Stealth Series Sights Features The Night Fision Optics Ready Stealth Series front sight uses the company s patented injection molded sleeve to hold its tritium vial in place creating what Night Fision calls The Perfect Dot for maximum visibility in low light. Unlike aluminum sleeves with a painted-on ring this design produces a brighter more durable ring that resists chipping and fading over time. The front sight features a yellow fluorescent ring for fast daylight acquisition alongside its tritium glow for nighttime use. A plain black rear sight completes the set keeping the sight picture uncluttered for quick target transitions. Both sights are finished in a matte black nitride coating that resists corrosion and wear from daily carry and holstering. The set is built specifically to fit the Glock 43X MOS dropping into the factory sight dovetails without requiring modification. Its .220 to .227 inch blade height is matched to the pistol s slide geometry for a proper sight picture out of the box. Shooters looking to upgrade the factory sights on their Glock 43X MOS will find this Night Fision set for sale at GrabAGun.
