Let’s Dive into SightMark Laser Bore Sight, 45 ACP, SM39017 – 1 out of 29 models
The SightMark Laser Bore Sight, 45 ACP, SM39017 – 1 out of 29 models promises a faster, more efficient way to zero your .45 ACP firearm. Made by SightMark, this laser bore sight aims to reduce wasted ammo and get you on target quickly. For someone who’s spent countless hours and dollars sighting in firearms, the promise of a quicker, less wasteful method is definitely appealing.
My quest for this bore sight stemmed from years of frustration with traditional sighting methods. I was tired of burning through boxes of ammunition just to get a new optic dialed in, and my shoulder was certainly complaining. The SightMark bore sight offered a potential solution to both problems: saving money and reducing felt recoil.
Upon unboxing, the SightMark Laser Bore Sight, 45 ACP, SM39017 feels surprisingly lightweight. The plastic construction doesn’t immediately inspire confidence, but it does make it easy to handle. The included carrying case is a nice touch, keeping the bore sight and batteries organized.
I considered other bore sights, including magnetic models and those with expanding arbors. However, the cartridge-style design of the SightMark seemed simpler and less prone to damaging the barrel. I chose this specific model due to the .45 ACP chambering and the seemingly straightforward operation.
My first impression was cautiously optimistic. The device seemed simple enough to use, but I was skeptical about its accuracy and durability. I was eager to get to the range and see if it lived up to its claims.
Real-World Testing: Putting SightMark Laser Bore Sight, 45 ACP, SM39017 – 1 out of 29 models to the Test
First Use Experience
I tested the SightMark Laser Bore Sight, 45 ACP, SM39017 at my local shooting range. The range offered both indoor and outdoor lanes, and I opted for the 25-yard indoor lane to minimize environmental factors. I primarily use a 1911 platform and this caliber is staple in my inventory, making the bore sight perfectly suited for my firearms.
Conditions were controlled, with consistent lighting and minimal wind. Inserting the bore sight into the chamber was straightforward, just like loading a regular cartridge. The red laser dot appeared clearly on the target, even under the range’s bright lights.
I immediately noticed that the laser dot wasn’t perfectly centered on the target, even at a relatively short distance. This required some mental adjustment when aligning my sights, meaning it got me in the ballpark but did not allow for a perfect zero, which defeats some of the purpose. The adjustment process was much less precise than I had hoped.
Extended Use & Reliability
After several weeks of sporadic use, the SightMark Laser Bore Sight, 45 ACP, SM39017 has held up reasonably well, but the initial issues have persisted. The plastic housing shows no significant wear, but the battery compartment feels flimsy and I worry about its longevity. The batteries have also started to loosen on occasion which makes for inconsistent readings.
Cleaning the bore sight is simple; a quick wipe with a cloth is usually sufficient. Storing it in the included case protects it from dust and impacts. My biggest concern is the inconsistent laser dot, which makes precise zeroing difficult.
Compared to my previous method of visually aligning the bore with the target, the SightMark offers a marginal improvement in speed, but not in accuracy. In fact, the visual bore alignment allows for a higher degree of precision. It doesn’t drastically outperform my old methods, which is a bit disappointing.

Conclusion on SightMark Laser Bore Sight, 45 ACP, SM39017 – 1 out of 29 models
The SightMark Laser Bore Sight, 45 ACP, SM39017 offers a simple and affordable way to get your .45 ACP firearm close to zero. Its ease of use and lightweight design make it appealing for beginners. However, its plastic construction and inconsistent laser dot raise concerns about durability and precision.
At $35.99, the price is justified for what it offers, which is a basic bore-sighting tool that will get you in the neighborhood, so to speak. Just don’t expect pinpoint accuracy straight out of the box. It is a great tool for starting the zeroing process.
I would cautiously recommend it, with the caveat that it’s not a substitute for careful live-fire zeroing. Verify the accuracy of the bore sight with live rounds and be prepared to make adjustments. If you’re looking for a quick and easy way to save a bit of ammo, the SightMark might be worth a try.
