💡 Why Add a Flashlight to Your AR-15?
A dedicated AR flashlight:
-
✅ Improves target ID in low-light or no-light environments
-
✅ Provides momentary and constant-on illumination
-
✅ Mounts securely to M-LOK, KeyMod, or Picatinny rails
-
✅ Works with optional remote pressure switches for fast activation

🔌 Mounting & Compatibility
Our AR flashlights are designed to mount on:
- Picatinny rails (MIL-STD 1913)
- M-LOK handguards (with adapters)
- KeyMod rails (select models)
Most models come with the necessary brackets or include offset mounts and adapters. If your rifle doesn’t have enough rail space, we offer cantilever and inline mounts to customize your setup.
❓ AR-15 Flashlight FAQs
Q: Can I use these flashlights on an AR pistol?
Absolutely. Most models are compact and lightweight enough for AR pistols, assuming you have the proper rail space.
Q: What’s better—flashlight only or flashlight with laser?
That depends on your use. A flashlight/laser combo gives you target identification and aiming assist, while a light-only setup keeps things simpler and lighter.
Q: Do I need a pressure switch?
If you plan on using your support hand to activate the light quickly, especially in a defensive or tactical setting, a pressure switch is a smart addition.
Q: Are these waterproof or shockproof?
Yes—most flashlights we sell are waterproof, recoil-rated, and built to withstand heavy-duty use.
