Angry Bear Arms Optic Height Sights — Glock, Lower 1/3 Cowitness
Stronghold Armament is now offering Angry Bear Arms sights — precision-machined, American-made iron sights built specifically for optic-equipped Glocks. This set pairs a blank black rear sight with a tritium front, dimensioned to sit correctly in a lower 1/3 cowitness position through your optic's window.
The blank rear keeps your sight picture clean and uncluttered when you're running the dot as your primary aiming reference, while the tritium front still gives you a fast, visible backup reference in low light if the optic ever fails or powers down.
Features
- Optic-height profile, dimensioned for lower 1/3 cowitness with common red dot optics
- Blank (no dot/notch marking) black rear sight for a clean, distraction-free sight picture
- Tritium front sight for glow-in-the-dark visibility in low-light conditions
- Precision-machined steel construction
- American made
Compatibility
Fits standard Glock-pattern slides milled for factory-width sights. Confirm your specific slide's sight cut (standard vs. Glock MOS/optic-ready dimensions) before ordering, as cowitness height varies by optic mounting system.
Why Lower 1/3 Cowitness
A lower 1/3 cowitness places your iron sights in the bottom third of the optic window rather than directly overlapping the dot. This keeps the sight picture uncluttered during normal dot-focused shooting, while still giving you a fast, natural transition to irons if you need a backup — without the irons crowding or partially blocking the optic's window like a standard-height or absolute cowitness set can.
FAQ:
What does "blank rear" mean?
The rear sight has no dot, notch marking, or U-shape reference — just a flat black rear blade. This is intentional for optic-focused shooters who want the cleanest possible sight picture with no visual clutter competing with the red dot.
Will these work with my specific optic?
These are dimensioned for a lower 1/3 cowitness, which works well with most popular micro red dots (Holosun 507C/407C, Trijicon RMR, etc.) on a factory or MOS-cut slide. Cowitness height can vary by optic and mounting plate thickness — contact us if you're unsure about your specific setup before ordering.
Do these fit a standard (non-optic-ready) Glock slide?
Yes, but No — these are designed for optic-height sight cuts. If your slide isn't milled for an optic, standard-height sights are the correct choice instead.
