Description
Sighting in a fresh scope the old way means burning through a stack of ammo just to get on paper. The Allen X-Ring Laser Boresighter takes most of that guesswork out of the equation. You attach the right adapter, drop in the laser, and it projects a bright dot downrange that shows you where the bore is actually pointing. From there you dial your crosshairs or iron sights onto the dot, and you'll be close to zeroed before the first shot leaves the barrel.
What makes this one worth keeping in the range bag is its range of fit. The kit adapts to rifles from .177 all the way up to .50 caliber, plus 12 and 20 gauge shotguns, so one tool covers just about everything in a mixed gun safe. The body is built from steel rather than cheap plastic, which is a nice touch on a piece that gets tossed around and handled a lot. A positive on/off switch means the laser isn't draining the battery every time it rattles around in your gear.
Getting the Most Out of the X-Ring Boresighter
The setup is straightforward enough that first-timers won't get lost. Thread on the adapter that matches your bore, seat it snug against the crown, flip it on, and adjust your optic to the dot. Folks who've run it report getting on paper at 100 yards with only minor fine-tuning left to do at the range, and it plays nice even with a muzzle brake threaded on. Always double-check the firearm is unloaded and pointed somewhere safe before you start, and pull the unit out before you send any live rounds.
What Comes in the X-Ring Kit
Allen sets this up as a value pack, so you're not hunting down extras before your first use. The boresighter arrives with the adapters and mounting screws you need for assembly, plus a CR2 battery already included. Toss it in your toolbox or range bag and it's ready whenever you mount a new optic or want to confirm an existing zero without wasting a box of shells.

Frequently Asked Questions
How does the Allen X-Ring Laser Boresighter work?
You thread on the adapter that fits your caliber or gauge, seat it against the muzzle crown, and switch on the laser. It projects a bright dot downrange showing where the bore is aimed, and you adjust your scope or sights to line up with that dot. This gets you close to zero before firing, so you spend less time and ammo at the range.
Will the X-Ring Boresighter fit my rifle and shotgun?
It covers a wide range, fitting rifles from .177 all the way up to .50 caliber along with 12 and 20 gauge shotguns. The included adapters let one tool serve most of the guns in a typical safe. That versatility is a big part of why it earns a spot in the range bag.
Does the boresighter come with a battery?
Yes, Allen includes a CR2 battery in the box, so it's ready to use right out of the package. The positive on/off switch also helps stretch battery life since the laser isn't running while it's stored. That means less worry about a dead battery when you actually need it.
Does it work on rifles with a muzzle brake?
It does. Users have run it on rifles fitted with a muzzle brake and still landed on paper at 100 yards with only light fine-tuning needed afterward. Just make sure the adapter seats properly against the crown for the best alignment.
