Flatback/Invincible Glock Switch – Semi/Full Auto Modes

Original price was: $210.00.Current price is: $180.00.

The original flatback switch was always “hot”—meaning once you installed it, you were locked into full-auto mode with no going back. Well, 2026 just changed the game. Our new Select-Fire Flatback Switch adds full toggle control, while staying just as stealthy

What is a flatback or incognito switch

Think of the flatback switch as the undercover agent of auto sears. It tucks flush against the back of your Glock’s slide so discreetly, you’d have to squint to know it’s even there. Unlike older switches with big selector buttons or safety notches, this one is all about subtlety. Our latest versions bring semi-auto and full-auto modes without breaking the flatback’s clean aesthetic. No knobs, no switches sticking out—just smooth operation.

Smooth as Stock: Flush-fit design with zero protrusion.
OEM Vibes: Looks like factory parts—because blending in is the mission.
Disguised to the Nines: Some even mimic Glock markings or slide cuts to complete the illusion.
