AR-15 Flash Hider
AR-15 Flash Hider – Control Muzzle Flash & Stay Stealthy
Sick of that blinding fireball lighting up your barrel every time you pull the trigger? An AR-15 flash hider is one of the simplest, most effective upgrades you can bolt on to your rifle — especially if you shoot in low light or run a defensive setup. It keeps your flash signature low, protects your vision, and makes you less visible to others. That’s a win on every front.
Here at Mounts Plus, we carry a wide selection of AR-15 flash hiders designed to tame muzzle flash without breaking the bank. Whether you want a classic birdcage, a minimal-profile suppressor, or something more aggressive looking, you’ll find it here.
Why Add a Flash Hider to Your AR-15?
Flash hiders — sometimes called flash suppressors — scatter the hot gas that exits your barrel so you don’t get that bright, fireball effect. That’s especially useful when you’re:
- Shooting at night or indoors
- Using night vision
- Trying to reduce your visual signature
- Protecting your vision and follow-up shot timing
Sure, it doesn’t reduce recoil — that’s not the point. Flash hiders are about stealth, speed, and eye protection. For defensive use or duty-style setups, they’re practically essential.

FAQ
What does a flash hider do on an AR-15?
A flash hider disperses the burning gases that exit your barrel when you shoot, which reduces the visible flash. This helps protect your night vision, hides your position better, and makes shooting in low light much more manageable.
What’s the difference between a flash hider and a muzzle brake?
A flash hider reduces the fireball. A muzzle brake reduces recoil. Some hybrid devices do a bit of both, but most AR-15 flash hiders are optimized for flash suppression, not recoil control.
Is a flash hider legal in my state?
That depends. States like California, New York, and others have restrictions on flash suppressors. Always check your local laws before buying or installing a muzzle device.
Do I need a crush washer to install it?
Yes — unless it’s timed differently or comes with shims. Most flash hiders work best when properly indexed with a crush washer, which we also carry.
Will this fit a .300 Blackout barrel?
If your .300 BLK barrel is threaded 5/8x24, this won’t fit. These flash hiders are designed for 1/2x28 threaded barrels typically used on 5.56/.223 rifles.
