NcStar APRLSMG Compact 5mW Green Laser Sight with Pressure Switch, 532nM Wavelength, Black Anodized Aluminum, Weaver Style Clamp

The NcStar APRLSMG is a compact green laser sight built for shooters who want a reliable aiming solution on AR platforms, pistols, or any rifle equipped with Weaver or Picatinny rail systems. At just 3.8 ounces and running a 532nm wavelength at under 5mW output, this green laser sight delivers a visible dot in moderate to bright conditions without the bulk of larger optic systems. It's especially useful for close to intermediate-range shooting, training, or as a backup aiming method when speed matters more than precision.

What makes the APRLSMG practical for the field is its dual-control setup: a momentary end-cap switch for quick on-off operation, plus a remote pressure switch that lets you activate the dot hands-on during shooting. The fully adjustable windage and elevation allow you to dial the laser point of aim to match your actual point of impact, so you're not guessing. Black anodized aluminum construction means it'll hold up to regular use without flash or corrosion concerns.

Setup is straightforward thanks to the included Weaver clamp and mounting tool—no gunsmith needed. A CR123A lithium battery (included) powers the unit, and the compact footprint won't interfere with optics mounted forward or compromise your sight picture. Whether you're running it on a home-defense rifle, training platform, or backup tactical setup, this is a no-nonsense green laser sight that does the job without unnecessary features or price markup.

Frequently Asked Questions

Will this green laser fit my AR-15 or tactical rifle?

Yes. The NcStar APRLSMG uses a Weaver/Picatinny clamp that works with any rifle or pistol equipped with standard Weaver or Picatinny rail systems. This includes most AR platforms, shotguns with rail-ready fore-ends, and many modern rifles.

What's the difference between the end-cap switch and the remote pressure switch?

The momentary end-cap switch is located on the rear of the laser and lets you toggle the dot on and off with your thumb or finger. The included remote pressure switch connects via cable and mounts separately, so you can activate the laser while keeping your grip on the firearm—useful for tactical shooting or one-handed operation.

How long does the CR123A battery last?

One CR123A battery is included with the laser. Runtime depends on usage pattern and operating conditions, but CR123A batteries are widely available and affordable. Since this unit uses a single standard battery, replacements are easy to source.

Can I adjust the point of aim after I mount it?

Yes. The laser is fully adjustable for windage and elevation. An adjustment tool is included in the box, so you can dial the dot to match your firearm's actual point of impact without additional tools.
