Viridian 9120036 HS1 Hand Stop Laser M-LOK Mounted 5mW Red Laser with 100 yds Day/2 mi Night Range & Black Finish for AR-Platform

The Viridian HS1 Hand Stop Red Laser for AR-Platform rifles combines two essential features into one M-LOK mounted accessory: a functional hand stop for consistent grip control, and an integrated red laser sight for rapid target acquisition. If you run an AR and want a laser that doesn't eat up rail real estate, this is a straightforward solution that keeps your setup compact while adding aiming capability across a range of shooting distances and light conditions.

The HS1's pressure-activated button sits in an ergonomic position that works naturally whether you're using a thumb-over grip, C-clamp, or other common AR hold. That means you can activate the laser without fumbling for controls or breaking your shooting stance—a big plus in a defensive or duty context where speed matters. The red laser is visible out to 100 yards in daylight and extends range to roughly 2 miles under low light, giving you flexibility from tactical ranges to outdoor hunting scenarios where you want a backup aiming tool.

Windage and elevation are adjustable, so you can zero the laser to your rifle's point of aim. The HS1 ships in black and is built to handle operating temperatures from 14°F to 140°F, covering most hunting and shooting seasons without flinching. Battery life on constant activation runs about 1.5 hours, and it uses a 1/3 N battery type.

Frequently Asked Questions

Does the HS1 work with standard AR-15s and other AR-platform rifles?

Yes—it mounts via M-LOK, which is standard on most modern AR handguards. As long as your rail has M-LOK slots, the HS1 will mount directly without adapters.

Can I use the hand stop and laser independently, or do they activate together?

The hand stop is a passive component that works anytime your hand is in contact with it. The laser activates separately via the pressure button, so you can use the hand stop for grip control alone, or activate the laser whenever you need it.

What battery does it take, and how long will one last?

The HS1 uses a 1/3 N battery. With continuous activation, expect about 1.5 hours of runtime per battery.

Is the laser visible in bright daylight?

Yes—the red laser is visible out to approximately 100 yards in daylight conditions. At night or in low light, effective range extends to around 2 miles.
