Description
The Aimshot AIMS Hunting Bore Sight Kit is built around the company's original patented chamber-style laser design, and it takes a lot of the guesswork out of setting up a new scope. Instead of burning through a box of ammo just to get on paper, you drop the brass laser module into the chamber, project the beam onto a target, and adjust your reticle to match. From there you head to the range knowing your first shots will land close to where you're aiming. It's a simple system that saves both time and money.
How the MBS223 Bore Sight System Works
The heart of this kit is the .223/5.56 laser module, which Aimshot uses as the foundation for their whole bore sighting lineup. The trick is the arbor system: hollow sleeves that slip over the .223 laser so it fits the chambers of other calibers. This kit ships with two of the most useful arbors, the AR243 and AR3006. The AR243 covers .308-based cartridges like .243 Win, .308 Win, and 7mm-08, while the AR3006 handles .30-06-based rounds. That gives you real coverage across the calibers most hunters actually own, and you can expand later since the module works with all 16 Aimshot rifle arbors.
Power Options That Keep You Going
One thing that sets the Aimshot MBS223 apart is the dual power setup. It runs on the included button cell batteries for quick closed-chamber work, but the included modular battery pack takes two AAA cells and stretches run time past 20 hours. That's a big jump over the roughly 10 minutes you get from button cells alone, so if you're sighting in several rifles or working through a long bench session, you won't be swapping cells constantly.
Getting the Most Out of Your Kit
A laser bore sight is meant to get you on paper, not deliver a finished zero. Set up around 25 yards on a stable rest or gun vise, line your reticle up with the laser dot, then confirm and fine-tune at your true distance with live fire. Done right, it turns a frustrating range trip into a quick one. Keep it in the storage pouch and it's easy to grab whenever you mount a new optic or check last season's zero before the hunt.

Frequently Asked Questions
What calibers can I bore sight with the Aimshot Hunting Bore Sight Kit?
Out of the box the MBS223 laser handles .223 and 5.56 directly, and the two included arbors expand your coverage. The AR243 fits .308-based cartridges such as .243 Win, .308 Win, and 7mm-08, while the AR3006 covers .30-06-based rounds. Since the module works with all 16 Aimshot rifle arbors, you can add more calibers down the road without buying a whole new tool.
How long does the battery last on the MBS223?
The included button cell batteries are fine for quick, closed-chamber sighting sessions but only give you around 10 minutes of run time. Swapping to the included modular battery pack, which takes two AAA cells, stretches that to over 20 hours. If you're working through several rifles or spending real time at the bench, the AAA pack is the way to go.
Does a laser bore sight replace zeroing at the range?
No, and it's not meant to. Bore sighting gets your reticle roughly lined up with the barrel so your first shots land on paper, usually set up around 25 yards. From there you still need to confirm and fine-tune your zero with live fire at your actual shooting distance. Think of it as a head start that saves you ammo, not a final zero.
Why choose the Aimshot chamber-style bore sight over a muzzle-mounted laser?
Aimshot holds the original patent on the chamber laser bore sight, and dropping the module into the chamber avoids the fit issues you can run into with muzzle-mounted units, especially on rifles with a muzzle brake. The brass construction and caliber-specific arbors give you a consistent, snug fit. It's a solid pick if you want repeatable setup across multiple rifles.
