The Millett Series 100 Auto Front Sight (MPN: GL00004) is an aftermarket iron sight engineered for early-generation Glock handguns. Featuring an elevated .340-inch (8.64 mm) sight height, this solid steel front post is equipped with a high-visibility blaze orange ramp insert designed for rapid sight alignment and fast target acquisition during daylight shooting. The face of the ramp incorporates anti-glare horizontal serrations to deflect direct sunlight and prevent visual distortion. Engineered as a passive mechanical sight, it utilizes Millett's specialized stake-on/dual-crimp attachment method to deliver a secure, rugged interface capable of withstanding repetitive slide cycling forces.

Key Features

• Blaze Orange Ramp: High-contrast orange bar insert enhances rapid flash sight pictures and instinctual front-sight tracking in ambient daylight.
• Anti-Glare Serrations: Precision serrated ramp face eliminates distracting light reflection and sun glare.
• Elevated .340" Profile: Sits at a measured height of .340 inches (8.64 mm) to properly align with tall, adjustable aftermarket target rear sights.
• All-Steel Construction: Built from durable steel to withstand severe slide recoil forces and repeated range use.
• Stake-On Mounting Interface: Employs a dual-crimp staking design for permanent, rock-solid retention on compatible early-generation slides.

Who is the Millett Glock Front Sight with Orange Ramp for?

• Competitive Handgun Shooters — Requires an elevated .340-inch (8.64 mm) height profile on early Gen 1 to Gen 3 Glock pistols to properly match with tall adjustable rear target sights like the Millett Series 100 system.
• Daylight Target Shooters — Benefits from the high-contrast blaze orange ramp insert on this Glock front sight to achieve instant sight alignment and target acquisition under bright daylight range conditions.

Less suitable for: Low-light or nighttime shooting where passive ambient-reflection orange inserts fail to illuminate (a self-luminous tritium night sight is required), or modern Glock slides equipped with standard screw-on hex nuts and Glock MOS optics cuts, which cannot accept stake-on / dual-crimp mounting posts.
