Apex Optic Mount for HS 509T Footprint Optics to Glock Gen 6 Pistols

Description

The Arizona desert doesn’t care about your gear. Heat, dust, and relentless sun beat down on your pistol every time you step out. Your optic mount needs to handle that abuse without failing. This Apex Optic Mount is built for exactly that reality. Machined from solid billet steel in the Free State of Arizona, it’s designed to survive the 3,000g of acceleration your slide experiences with every shot. Aluminum mounts crack and tear off after a few thousand rounds — we tested 6061 and 7075 ourselves, and they couldn’t hold up. Steel doesn’t quit. The black PVD finish adds serious corrosion resistance, so sweat, rain, or range residue won’t eat through it. That matters when you’re running suppressed and the carbon blowback is heavy.

This mount is specifically made to fit Holosun 509T footprint optics onto your GLOCK Gen 6 Optic Ready slide. No adapter plates, no extra height, no slop. The mount drops directly into the factory cut and locks tight. Two 4mm x 0.7 mounting screws are included, each with a high-temp thread locker patch pre-applied. Torque them to 15 in-lb and you’re set. We recommend cleaning the slide surface before installation to ensure a solid bite.

• Built for Gen 6 slides — works with factory GLOCK Gen 6 Optic Ready cuts only. Not for Gen 5 or earlier.
• Steel construction — handles high round counts and heavy recoil without rail failure. Aluminum can’t match this durability.
• PVD black finish — resists corrosion from humidity, sweat, and cleaning solvents. Holds up in high-heat environments.
• Damper cavity under the front — reduces vibration and closes the light gap between the mount locking key and the slide. Keeps your zero consistent.
• Includes screws with pre-applied thread locker — no need to buy extra. Torque spec is 15 in-lb for proper retention.
• Made in Arizona — Apex manufactures the mount and hardware in the Free State of Arizona. Supports local production.

If you’re shooting suppressed, you know the extra gas and heat stress your gear. Steel handles thermal expansion better than aluminum, so your mount stays tight when the barrel gets hot. The PVD coating won’t flake or peel under sustained fire. Whether you’re running drills in the desert sun or stacking rounds at the range, this mount keeps your 509T footprint optic locked in place. No shifting, no loosening, no excuses.
