Introduction
The Tacticon Laser Boresighter is designed to assist in zeroing the optics or iron sights of .223 Rem and 5.56 mm NATO rifles without firing live ammunition. This device projects a visible laser beam, allowing for precise adjustments to your firearm's sighting system. It is constructed from durable brass and is lightweight for ease of use.
Key features include:
- Accuracy: Facilitates precise adjustment of optics or iron sights.
- Visibility: Laser is visible up to 100 meters in various lighting conditions.
- Durability: Crafted from rugged brass, weighing approximately 0.4 ounces.
- Power: Operates on three LR41 batteries, with two sets included for extended use.
Setup
Follow these steps to prepare your boresighter for use:
- Install Batteries: Unscrew the end cap of the boresighter. Insert three LR41 batteries with the positive (+) side facing the laser emitter. Ensure proper orientation. Screw the end cap back on securely. The laser should activate upon proper battery installation and cap tightening.
- Prepare Firearm: Ensure your rifle is unloaded and pointed in a safe direction. Engage the safety.
- Insert Boresighter: Gently insert the boresighter into the chamber of your .223 Rem or 5.56 mm NATO rifle. Carefully close the bolt to secure the boresighter in place. Avoid forcing the bolt, as this can damage the boresighter or the firearm.

Operating Instructions
Once the boresighter is installed, proceed with zeroing your sights:
- Position Target: Place a target at a desired distance (e.g., 25 yards, 50 yards).
- Aim Rifle: Rest the rifle securely on a stable surface. Aim the rifle so the laser dot from the boresighter is visible on the target.
- Adjust Sights: Adjust your rifle's scope or iron sights until the reticle or front sight post aligns with the laser dot on the target. Make small, precise adjustments.
- Verify Alignment: After initial adjustments, re-check the alignment by slightly moving the rifle and re-aiming to ensure the laser dot consistently aligns with your sights.
- Remove Boresighter: Once zeroing is complete, carefully open the bolt and remove the boresighter from the chamber.

- Cleaning: After each use, gently wipe the boresighter with a clean, dry cloth to remove any residue. Do not use harsh chemicals or abrasive materials.
- Battery Storage: Remove batteries when the boresighter is not in use for extended periods to prevent corrosion and battery drain. Store batteries in a cool, dry place.
- Storage: Store the boresighter in its protective packaging or a suitable case to prevent damage.
