Tipfun Bore Sight Cal 223 5.56mm: A Practical Tool for Quick Scope Zeroing
Getting a scope or red dot sight properly zeroed at the range can be a slow, ammunition-consuming process. The Tipfun Bore Sight for .223 and 5.56mm is one of those tools designed to speed things up by giving you a rough alignment before you fire your first shot. It’s a simple concept: a laser cartridge that fits into the chamber, projecting a red dot downrange to match where the barrel is pointing.
In use, the device is straightforward. You chamber it like a regular round, and the laser activates. Then, you adjust your optic until the reticle aligns with the laser dot at a known distance, typically around 25 to 50 yards. This gets you on paper, saving time and ammo. The Tipfun comes with two button-cell batteries included, which is a nice touch—no need to hunt down a separate purchase before you can test it.
The key functional features here are the caliber-specific design and the simple on/off mechanism. The .223/5.56mm version fits snugly into the chamber, though you’ll want to ensure the bolt closes gently to avoid damaging the laser unit. The red dot is visible in low light, but it’s not bright enough for use in direct sunlight at longer ranges—a common limitation of budget bore sights. You’ll need a shaded area or overcast conditions to see the dot clearly beyond 25 yards.
One trade-off worth noting is that this is a chamber-type bore sight, not a muzzle-mounted one. That means it aligns with the bore axis, but the laser’s position can shift slightly if the cartridge doesn’t seat perfectly. For precision rifles, this can introduce a small error. Also, the laser isn’t adjustable for windage or elevation—it’s fixed, so you rely entirely on your scope adjustments. If the laser is off by a few inches at 50 yards, you might chase it with your scope, only to find the real bullet impact is slightly different. This isn’t a precision instrument; it’s a rough guide.
Comparing this to a laser bore sighter that mounts in the muzzle, the Tipfun’s chamber design is more convenient for repeat use because you don’t have to remove the bolt or attach anything to the barrel. But muzzle-mounted laser sights often have a more stable alignment and can be used with multiple calibers if you buy adapters. The Tipfun is caliber-specific, so if you own multiple rifles, you’d need separate units for each. That said, at its price point, it’s cheaper than a universal kit.
Who is this for? It’s suitable for casual shooters, hunters, and anyone who wants to save a bit of ammo during initial scope setup. It works well for AR-15s and similar rifles chambered in .223 or 5.56mm. It’s not ideal for long-range precision shooters who demand sub-MOA accuracy from their zeroing process, or for those who shoot in bright desert conditions where the laser dot is barely visible. It also won’t replace the need for final live-fire confirmation—every bore sight has a margin of error, and this one is no exception.
On the downside, the build quality feels a bit plastic-y. The cartridge body is made of metal, but the laser housing and cap are plastic. Over time, the battery compartment can loosen, and the laser may flicker if the contacts are dirty. Some users have reported that the laser stops working after a few uses, though this varies. It’s a budget tool, and it performs like one—adequate for the price, but not something you’d rely on for competition-grade gear.
Overall, the Tipfun Bore Sight does what it’s supposed to do: get you close to zero without burning through a box of ammunition. It’s a practical helper, but it’s not a shortcut to perfect accuracy. If you’re patient and understand its limitations, it can save you time. If you expect pinpoint precision straight out of the box, you’ll be disappointed. It’s a tool for the range bag, not the gunsmith’s bench.
