First Impressions of P2M 7.62x39mm Caliber Laser Bore Sighter
The P2M 7.62x39mm Caliber Laser Bore Sighter promises a quick and easy way to get on paper without burning through precious ammunition. Manufactured by P2M, this in-chamber bore sighter utilizes a red laser to project a point of aim, allowing for initial sight adjustments before heading to the range. At a price point hovering around $20, it’s an enticing option for budget-conscious shooters looking to save time and money.
I’ve always been a stickler for efficient zeroing. Wasting rounds trying to get on target has always felt like a cardinal sin, especially with today’s ammunition prices and availability. The P2M 7.62x39mm Caliber Laser Bore Sighter seemed like a practical solution to this problem.
Upon receiving the P2M 7.62x39mm Caliber Laser Bore Sighter, my initial impression was of its compact size and lightweight aluminum construction. It felt surprisingly solid for its price. Compared to magnetic bore sighters that attach to the muzzle, this in-chamber design seemed potentially more precise and less prone to accidental movement.
I had considered other options like universal bore sighters, but the dedicated caliber specificity of the P2M seemed like it would provide a more secure and accurate fit for my 7.62x39mm rifles. My first thought was, “If this thing even gets me close, it’ll be worth the price.” I was cautiously optimistic.
Real-World Testing: Putting P2M 7.62x39mm Caliber Laser Bore Sighter to the Test
First Use Experience
I tested the P2M 7.62x39mm Caliber Laser Bore Sighter at my local outdoor shooting range before a proper zeroing session with my SKS rifle. The day was clear, but slightly breezy, which can sometimes affect laser bore sighter accuracy, especially at longer distances. The process was simple: insert the bore sighter into the chamber, close the bolt, and observe the red laser dot on the target.
Initially, the dot was significantly off from my iron sights at 25 yards. However, using the laser as a guide, I was able to make substantial adjustments to my sights before firing a single round. This saved a considerable amount of time and ammunition. I did notice that the dot flickered slightly when the bolt was fully closed, indicating a potentially imperfect fit within the chamber.
Extended Use & Reliability
After several range trips spanning a couple of months, the P2M 7.62x39mm Caliber Laser Bore Sighter has remained a useful, though not perfect, tool. It still provides a good starting point for sight adjustments. The aluminum construction has held up well, showing no signs of wear or damage despite being tossed in my range bag.
Cleaning is simple; a quick wipe with a dry cloth is usually sufficient. It’s important to note that the battery life is limited. I found myself replacing the LR41 battery after approximately 2 hours of total use. While it outperforms the frustration of blindly adjusting sights, the flickering laser dot and limited battery life are notable drawbacks.

Performance & Functionality
The P2M 7.62x39mm Caliber Laser Bore Sighter performs its primary function – getting you close to zero – adequately. It significantly reduces the number of rounds needed for initial sight adjustments. However, it’s not a substitute for final zeroing at the range.
The main strength is its simplicity and speed. It’s quick to use and requires no specialized knowledge. The weakness lies in its precision. The laser dot isn’t perfectly stable, and the bore sighter itself can have slight variations in its positioning within the chamber. This means the initial zero will need fine-tuning with live ammunition.
Design & Ergonomics
The aluminum construction feels solid, although not premium. Its lightweight design doesn’t add noticeable weight to the rifle. The P2M 7.62x39mm Caliber Laser Bore Sighter is designed to mimic a standard cartridge, making it incredibly user-friendly.
There’s virtually no learning curve. Just chamber it like a regular round.
Durability & Maintenance
Given its aluminum construction, the P2M 7.62x39mm Caliber Laser Bore Sighter should last for a reasonable amount of time with proper care. The main concern is the battery compartment, which could potentially be vulnerable to damage if overtightened. Maintenance is minimal; just keep it clean and dry.
Accessories and Customization Options
The P2M 7.62x39mm Caliber Laser Bore Sighter doesn’t come with any accessories beyond the included battery. There are no customization options available. It’s a simple, self-contained tool. It is compatible with any optic or sight system mounted on a 7.62x39mm rifle, as it simply provides a visual reference point for initial adjustments.
Pros and Cons of P2M 7.62x39mm Caliber Laser Bore Sighter

- Significantly reduces wasted ammunition during initial sight-in.
- Simple and easy to use, requiring no specialized knowledge.
- Lightweight and durable aluminum construction.
- Affordable price point.
- Provides a good starting point for zeroing, even if not perfectly precise.
Cons
- Laser dot can be slightly unstable or flicker, reducing precision.
- Limited battery life requiring frequent LR41 battery replacements.

Who Should Buy P2M 7.62x39mm Caliber Laser Bore Sighter?
The P2M 7.62x39mm Caliber Laser Bore Sighter is perfect for budget-conscious shooters who own 7.62x39mm rifles (like the SKS or AK-47) and want to save ammunition during the initial sight-in process. It’s also suitable for those who frequently swap optics and need a quick way to get back on paper. It’s a great tool for new gun owners learning the zeroing process.
Those seeking pinpoint accuracy right out of the gate should skip this product. Competitive shooters and long-range enthusiasts will likely find its precision insufficient. A must-have accessory is a supply of LR41 batteries.
Conclusion on P2M 7.62x39mm Caliber Laser Bore Sighter
