Laser

Laser Types

Visible (Red/Green): Can be seen with the naked eye. Green is easier to see in daylight than red. Used for CQB and civilian defensive applications.

Infrared (IR): Only visible with night vision devices (NVDs). Standard for military and LE night operations. Useless without NVGs.

Dual (Visible + IR): Both beams in one unit. Maximum flexibility for varied conditions.

Designator Classes

Class 1/Class 3A: Eye-safe visible lasers. Consumer legal, suitable for most uses.

Class 3B: More powerful, can cause eye injury. Restricted (typically IR for military/LE).

IR Illuminator: Not a pointer but a "flashlight" in IR spectrum. Illuminates for NVG use.

Key Features

Adjustability: Windage and elevation for zeroing. Quality units hold zero under recoil.

Activation: Pressure switches, push buttons, or constant-on options. Remote pressure switches are highly recommended.

Power Source: CR123A or AAA common. Battery life varies significantly between visible and IR use.

Popular Configurations

Pistol/Compact: Small units for CQB or pistol use. Examples: Streamlight TLR-8, Crimson Trace.

Full-size Rifle: Larger units with more features. Examples: Steiner DBAL, L3 ATPIAL (PEQ-15).

Combo Units: Combined light and laser in one package. Streamlines controls.

Limitations

Range: Visible lasers have limited effective range, especially in daylight. Beam disperses at distance.

Visibility: Red lasers nearly useless outdoors in daylight. Green better but still limited.

Target Indication: Your laser shows the target where you're aiming—both ways.

Battery Dependency: When the battery dies, so does your aiming solution.

Use Case Considerations

Lasers are most effective for:

• Close quarters where speed beats precision
• Night vision operations (IR)
• Situations where you can't get a proper cheek weld
• As a training aid to diagnose trigger control

They're less effective for:

• Precision shooting at distance
• Daytime outdoor use (visible lasers)
• Primary aiming solution on a rifle

For most civilian AR-15 uses, a quality optic and weapon light serve better than a laser. Lasers excel in specific niches—know if yours fits before investing.
