ON PAPER, FIRST SHOT
True-to-bore alignment puts your point of aim where the barrel actually points. Your first round is on paper, not in the berm.
Get on paper before your first live round. Zero in 2-4 shots, not 2 boxes of ammo.

Built to actually get the job done
No gimmicks. Spend less time sighting in and more time shooting.

-
Visible in full daylight
The green beam stays easy to pick up in full sun where red washes out. Zero outdoors to 50 yards, or up to 100 indoors.
-
One kit, every gun you own
Six tool-free adapters for .22 – .50 cal plus 12GA and 20GA. Rifles, pistols, and shotguns. Batteries and case included.
-
Pays for itself fast
Zeroing the old way burns 15–20 rounds per gun. At centerfire prices, the X03 pays for itself by your second zero.
Zeroed in three steps
If you can load a magazine, you can use the X03.
-
Seat it
Pick the adapter for your caliber or gauge and seat the X03 in the muzzle. Tool-free.
-
Match the dot
At 15-25 yards, adjust your optic until the reticle meets the green dot.
-
Confirm & go
Fire 2-4 rounds to confirm, fine tune, done. Head home, money saved.

FAQ
How accurate is the X03? Can it really get me on paper?
Yes, easily. The X03 does its job. The X03 seats snug in your bore, so the dot shows exactly where the barrel points. That puts your first round on paper at 25 yards, and most shooters confirm zero within 2–4 rounds.
Should I get the Red or Green version?
Choose Green (X03) if:
✓ You zero outdoors or in bright daylight
✓ You shoot at 50+ yards
✓ Visibility is critical (e.g., aging eyes, bright sun)
Choose Red if:
✓ You mainly zero indoors or low-light
✓ You want longer battery life
Pro tip: 80% of our customers choose Green for the daylight visibility advantage. The pulsing beam also helps distinguish it from your reticle.
Will X03 work with a subcompact gun?
Yes, as long as the barrel is at least 2.25 inches long, excluding the chamber.
How is this different from a magnetic bore sight?
Magnetic bore sights mount on the muzzle externally, they're quick but less accurate due to slight tilt variations.
The X03 inserts directly into the bore, providing more precise alignment along the actual barrel axis. This is the same principle
used by professional gunsmiths.
Trade-off: Slightly slower setup (10 seconds vs 5), but significantly more accurate.
What calibers does this bore sight work with?
It works with most common and popular calibers from.22 to.50.
It is not recommended for subcompact or short-barrel handguns, or rifles with long muzzle devices.
Will the adapters damage my barrel?
No. The adapters are made of precision-machined brass and aluminum (softer than steel barrels) — they cannot scratch or damage rifling.
The fit is snug but designed for easy insertion and removal without force. Always ensure the barrel is clean before insertion.
Concerned about expensive firearms? We've tested with Cerakote, chrome-lined, and polygonal rifling — no issues reported.
Why does the green laser flash?
The flashing beam is intentional and serves three purposes:
1. Easier identification: Distinguishes the laser dot from your reticle, other lights, or reflections
2. Daylight visibility: The intermittent flash is easier to spot against bright backgrounds than a steady beam
3. Battery efficiency: Extends battery life by ~40%
This does not affect zeroing accuracy — the pulse is fast enough that the dot appears continuous to the human eye.
Is the laser eye-safe?
The X03 uses a Class 3R laser (5mW±0.2mW) — the same classification as most consumer laser pointers.
Safety guidelines:
⚠️ Always treat firearms as loaded — verify chamber is empty before installing the bore sight
⚠️ Never look directly into the laser beam
⚠️ Don't point at people, animals, or aircraft
⚠️ Class 3R is safe for momentary exposure but can cause eye damage with prolonged direct viewing
