Let’s Talk About Tiger Rock .303 British Cartidge Laser Bore Sighter
The Tiger Rock .303 British Cartridge Laser Bore Sighter promises a quick and easy way to get your .303 British rifle roughly zeroed before heading to the range. Made by Tiger Rock, it utilizes a laser diode housed in an aluminum cartridge to project a red dot, allowing for initial sight alignment without firing a shot. This little tool aims to save you time and ammunition, but does it live up to the promise, especially at its budget-friendly price point?
My journey to acquiring the Tiger Rock .303 British Cartridge Laser Bore Sighter stemmed from a frustrating experience at the range. I had recently mounted a vintage scope on a Lee-Enfield No. 4 Mk I, and the initial shots were so far off that I nearly ran out of adjustment range on the scope. I needed a quicker, less ammo-intensive way to get on paper, and the Tiger Rock bore sighter seemed like a potential solution.
Upon unboxing, the bore sighter felt surprisingly solid, given its price. The aluminum casing seemed reasonably well-machined, though the metallic finish lacked the polished look of higher-end models. It came with three LR41 batteries already installed, a welcome touch.
I considered other bore sighting options, including magnetic models that attach to the muzzle and more expensive cartridge-style lasers. Ultimately, the Tiger Rock won out due to its specific .303 British chambering and incredibly low price. Could it be a hidden gem, or would it prove that you get what you pay for?
My initial excitement was tempered by a healthy dose of skepticism. At this price point, I wasn’t expecting perfection, but I was hoping for a tool that would at least get me close to zero. Would it be accurate enough to make a difference, or would it be just another cheap gadget destined for the back of the drawer?
Real-World Testing: Putting Tiger Rock .303 British Cartidge Laser Bore Sighter to the Test
First Use Experience
I first tested the Tiger Rock .303 British Cartridge Laser Bore Sighter in my workshop before heading to the range. The setup was straightforward: simply insert the bore sighter into the chamber of my Lee-Enfield, then align the scope reticle with the projected red dot on a target placed about 25 yards away. The red dot was visible, but not particularly bright, even in relatively low light.
I noticed that the dot seemed to shift slightly as I rotated the cartridge in the chamber. This raised concerns about accuracy. It was manageable, but definitely something to note.
After making the initial adjustments, I took the rifle to the range. I was relieved to find that my first shot landed on paper, only a few inches from the bullseye. This was a significant improvement compared to my previous range trip.
Extended Use & Reliability
After several range sessions, the Tiger Rock .303 British Cartridge Laser Bore Sighter has proven to be a useful, albeit imperfect, tool. It consistently gets me on paper, saving both time and ammunition. The initial dot shift is still present, requiring a careful average when aligning sights, which can be tedious.
The aluminum casing has held up well with no visible signs of wear. Maintenance is minimal, simply requiring occasional cleaning with a dry cloth and battery replacement as needed.
Compared to previous attempts at bore sighting using just my eye and the rifle’s bore, the Tiger Rock is a clear winner. While it doesn’t replace a proper zeroing process at the range, it significantly speeds up the initial setup. It doesn’t outperform more expensive options, but given the price, it performs admirably.
Breaking Down the Features of Tiger Rock .303 British Cartidge Laser Bore Sighter
Specifications
The Tiger Rock .303 British Cartridge Laser Bore Sighter is designed for use with rifles chambered in .303 British. It is constructed from aluminum with a metallic finish. The bore sighter emits a red laser beam with a wavelength between 635-655 nm and a laser beam of less than 5mW.
The product uses three LR41 batteries. According to Tiger Rock, the sighting range is 20-30 yards, and the dot size is approximately 1.5 inches at 100 yards. It features a universal gun model fitment, implying chamber fit is the only relevant specification.
- Caliber: .303 British
- Material: Aluminum
- Laser Wavelength: 635-655 nm
- Laser Beam Power: < 5mW
- Sighting Range: 20-30 yards
- Dot Size: 1.5″ @ 100 yards
- Battery Type: LR41 (x3)
- Finish: Metallic
- Color: Red
These specifications translate to a tool best suited for initial sight alignment at close ranges. The aluminum construction offers reasonable durability, while the red laser provides sufficient visibility for indoor or shaded outdoor use. The small dot size at 100 yards suggests potential for fine-tuning, but is ultimately limited by the device’s precision.
Performance & Functionality
The primary function of the Tiger Rock .303 British Cartridge Laser Bore Sighter is to project a visible laser dot down the barrel of a .303 British rifle, allowing the user to align their sights or optics with the point of impact. It achieves this function reasonably well, especially for the price. The bore sighter is reliable enough to consistently project the laser dot after each insertion.
However, there is a notable weakness: the slight shift in the laser dot’s position when the cartridge is rotated in the chamber. This imperfection affects the precision of the initial alignment. The product does meet the basic expectations, getting the shooter on paper without wasting excessive amounts of ammunition.
Design & Ergonomics
The aluminum construction of the Tiger Rock .303 British Cartridge Laser Bore Sighter provides a decent level of durability and is lightweight. The bore sighter is similar in size and weight to a .303 British cartridge, making it easy to handle. It is designed for simple insertion and removal from the rifle’s chamber.
The bore sighter is exceptionally user-friendly. There’s no complex setup or adjustment needed. The simple on/off function via battery removal means even novice shooters can operate it effectively.
Durability & Maintenance
Given its aluminum construction, the Tiger Rock .303 British Cartridge Laser Bore Sighter should last for a reasonable amount of time with proper care. The lack of moving parts minimizes the risk of mechanical failure. The metallic finish is reasonably scratch-resistant.
Maintenance is minimal. Simply wiping the bore sighter clean after use and storing it in a dry place is sufficient. Occasional battery replacement is the only maintenance required.
Accessories and Customization Options
The Tiger Rock .303 British Cartridge Laser Bore Sighter comes with the necessary LR41 batteries. There are no included accessories beyond that. There are no customization options available for this product.
The bore sighter is not designed to be compatible with accessories from other brands beyond the standard LR41 batteries.
