Multi-Caliber Brass Arbor for Serious Magnum Rifles

Supported Calibers (as listed):
Additional retailers also note compatibility with related Weatherby and magnum calibers like 270 Wby, 7mm Wby, 8mm, and .416 Rem Mag, making this one of the most versatile arbors in the AimShot system. sturgisguns.com+1
If you own multiple magnum rifles, AR264 lets you cover them all with one compact, caliber-specific adapter.
Designed for the AimShot .223 Laser Boresight Module
The AR264 is part of the modular AimShot Laser Boresight System, which uses a central .223 laser module combined with caliber adapters (arbors) to cover dozens of chamberings. Cheaper Than Dirt+1
Insert the AimShot .223 laser boresight into the AR264 arbor.
Insert the arbor (with laser installed) into the rifle’s chamber.
The system projects a laser precisely along the bore axis, giving you a clear point of reference on the target. Cheaper Than Dirt+1
This modular design means you buy the laser once and then equip it for multiple calibers using inexpensive brass arbors like the AR264—far more cost-effective than buying separate boresighters for each rifle.
Solid Brass Construction for Precise, Repeatable Fit
AimShot builds the AR264 from solid brass, chosen for its durability, chamber friendliness, and dimensional stability. AmmoJoy+3AimShot+3BattleHawk Armory+3
Material: 100% brass for precise machining and a snug, repeatable chamber fit.
Brass is gentle on chambers and extractors compared to some steel tools.
Corrosion-resistant and tough enough for frequent use across multiple rifles.
The tight, cartridge-specific profile helps keep the laser perfectly centered, which is critical for accurate bore alignment—especially with long-range magnum rifles.
Fast, Accurate Zeroing – Save Time & Ammo
Using the AimShot AR264 + .223 laser module drastically speeds up your zeroing process and reduces wasted ammunition: Cheaper Than Dirt+2KYGUNCO+2
Get “on paper” in minutes without multiple guess shots at close range.
Align your optic, red dot, or iron sights to the laser at 25–50 yards, then fine-tune with a few live rounds.
Ideal for scope changes, new optics, mount swaps, or confirming zero after travel.
For expensive magnum calibers, saving even a handful of rounds every time you change or check an optic adds up quickly.
Simple, Safe Operation
Using the AR264 is straightforward and doesn’t require any gunsmithing skills: Cheaper Than Dirt+1
Verify your rifle is unloaded. Remove the magazine and visually/physically clear the chamber.
Insert the AimShot .223 laser boresight into the AR264 arbor.
Carefully insert the arbor into the chamber like a live round.
Close the bolt gently, point the rifle at your target (in a safe direction), and turn on the laser.
Adjust your optic or sights until the point of aim matches the laser on the target.
Remove the arbor, load live ammo, and fire a few rounds to confirm and refine your zero.
Always follow safe firearms handling practices even when using a boresighter.
Ideal for Hunters, Long-Range Shooters & Gunsmiths
The Aimshot AR264 Arbor is especially useful for:
Big-game hunters running classic long-action magnums like .300 Win Mag, .338 Win Mag, and 7mm Rem Mag.
Long-range shooters who regularly tweak optics, swap scopes, or travel to different ranges.
Gunsmiths and armorers who mount optics on customer rifles in multiple magnum chamberings.
Enthusiasts with multiple Weatherby and Norma-based cartridges, who want one arbor to cover an entire family of rifles.
If you’re serious about making your zeroing process more efficient across several high-power rifles, the AR264 is a must-have accessory.
