How to Mount and Zero a Steiner DBAL-A2 on Your AR-15: Complete Guide

Introduction

The Steiner DBAL-A2 is one of the most reliable dual beam aiming lasers available for civilian and military use. This comprehensive guide will walk you through the proper mounting and zeroing procedures for your AR-15 platform.

What You'll Need

  • Steiner DBAL-A2 laser device
  • Appropriate mounting hardware (usually included)
  • Torque wrench
  • Blue Loctite
  • Night vision device (for IR zeroing)
  • Laser safety glasses
  • Target at 25 yards

Step 1: Choosing the Right Mounting Position

The DBAL-A2 should be mounted on the top or side rail of your AR-15's handguard. Most operators prefer the 3 o'clock or 9 o'clock position to avoid interference with optics and maintain a clean sight picture.

Key considerations:

  • Ensure clearance from your primary optic
  • Consider your shooting stance and hand placement
  • Verify the laser won't be blocked by accessories

Step 2: Mounting the DBAL-A2

Installation process:

  1. Clean the rail surface with degreaser
  2. Apply a small amount of blue Loctite to the mounting screws
  3. Position the DBAL-A2 on your chosen rail section
  4. Hand-tighten the mounting screws initially
  5. Use a torque wrench to tighten to manufacturer specifications (typically 15-20 inch-pounds)
  6. Verify the device is secure and properly aligned

Step 3: Initial Setup and Safety

Before zeroing:

  • Install fresh batteries
  • Familiarize yourself with the controls
  • Ensure you're in a safe shooting environment
  • Wear appropriate laser safety glasses
  • Verify your backstop is adequate

Step 4: Zeroing the Visible Laser

Daylight zeroing procedure:

  1. Set up a target at 25 yards
  2. Zero your rifle's primary optic first
  3. Fire a 3-shot group with your primary optic
  4. Activate the visible laser (red beam)
  5. Using the DBAL-A2's adjustment knobs, move the laser dot to match your point of impact
  6. Make small adjustments - each click typically moves the point of impact 1/2 MOA
  7. Fire another group to verify zero

Step 5: Zeroing the IR Laser

Night vision zeroing:

  1. Ensure you have proper night vision equipment
  2. Use the same 25-yard target
  3. Activate the IR laser mode
  4. View through your night vision device
  5. Adjust the IR laser to match your established zero point
  6. The IR and visible lasers should now be co-aligned

Step 6: Verification and Final Checks

Final verification:

  • Test both visible and IR modes
  • Verify zero at different distances if needed
  • Check that all mounting hardware remains tight
  • Document your zero settings
  • Test the device's durability with some light handling

Maintenance Tips

  • Regularly check mounting screw tightness
  • Clean the laser apertures with appropriate lens cleaning materials
  • Store with batteries removed for long-term storage
  • Re-verify zero after any impacts or rough handling

Troubleshooting Common Issues

Laser won't activate: Check battery installation and charge level

Inconsistent zero: Verify mounting hardware tightness and rail condition

Dim laser output: Clean apertures and check for obstructions

Conclusion

Properly mounting and zeroing your DBAL-A2 is crucial for effective use. Take your time during installation and always prioritize safety. With proper setup, your DBAL-A2 will provide reliable aiming capability in both daylight and low-light conditions.
