Useful but prepare to buy new batteries,
I bought the 9mm SightMark to zero in my Viridian X5L tactical green laser/light (Viridian Green Laser Sight with LED Tactical Light, with Universal Mount for All Weaver, or Picatinny Open Railed Handguns, Except Sub-Compact Models.)
As you might expect it’s a matter of putting the bore sight in, turn on your laser or red dot sight/holosight/scope – whatever sight you use – and your good to go.
The laser itself was visible up to 82 feet (25 metres) without problems (this is the maximum distance we shoot at, at our indoor range).
As with all red lasers, usage in daylight might be a problem, so I suggest to use it at an indoor range or around dusk.
As such the SightMark performs good and is useful.
The unit does not have an on/off switch (I guess due to its tiny size), so once you screw the cap on (which holds the batteries) it’s on and stays on until you unscrew it again.
Note that due to the bullet’s trajectory the red dot the bore sight shows you is not 100{660353129f8d892044c993645a1c75194301fec6786a7f617c15adde0b0011e9} accurate. However, for distances up to 82 feet you should not have to worry too much about that with 9mm ammo.
So far so good, but the three tiny batteries (AG1, 1,5v Alkaline batteries) that came with the unit are really crappy. Within less that 4 minutes the batteries ran out. However, after a few minutes they worked again. This is due to the nature of how Alkaline batteries work. They loose their voltage really fast and then run out.
4 minutes is way to short to zero-in your gun.
If you want better performance, get silver oxide batteries as they do not leak once they get old and have a better lifespan. Prepare for the fact that they are about 75-100{660353129f8d892044c993645a1c75194301fec6786a7f617c15adde0b0011e9} more expensive.
All in all a handy, useful tool, but SightMark needs to include better batteries (silver oxide and not dirt cheap alkaline) because it would enhance the “out-of-the-box” experience a lot.
For this reason I give it a 3 out of 5.
SightMark: if you read this, please deliver this bore sight in the future with better (silver oxide) batteries. For me it’s to late but for other customers you should change it.

|Works great. Get some SG5 silver oxide batteries at the same time,
I have four of the Sightmark laser boresights – the 12 gauge, 9mm, 7.62x39mm, and .223.
I had used a Bushnell laser boresight before getting this set of chamber loaded laser boresights. The Bushnell is the kind that you stick into the muzzle end of the gun, fitted with an arbor matched to the barrel size. The problem with this device was that the arbors never fit quite right – they were always either too tight or too loose, plus you had to try to seat the body of the boresight in the center of the opening of the barrel (or muzzle break) in order to properly align the center axis of the boresight with the center axis of the barrel. This rarely if ever happened just right as the slightest tilt in the seating of this boresight in the barrel would take it off the center axis so that rotating the laser would cause the laser light to mark out a small circle that was several MOA in diameter rather than being dead centered. Ugh.
Of course with these chamber loaded laser boresights, there is also the potential for the lasers to be mis-aligned off the center axis. Plus there is the potential for the boresight to not fit the chamber properly. The key is to find a brand that has a measure of quality control so that you aren’t stuck with these problems.
I read through a lot of reviews before deciding on Sightmark. It is definitely not the cheapest out there. There are so many different brands and generic versions of these chamber loaded laser boresights now that almost look alike, with many much cheaper than the Sightmark. However, it was clear from reading the reviews that as the prices went down, so did the quality control. Several of these cheaper brands came with complaints that the lasers were not aligned to the center axis (resulting in the laser painting a circle as it rotates in the chamber) or that they did not fit properly in the chambers and so would either get stuck or wiggle.
I have this theory that the really cheap laser boresights must be factory seconds or some such.
I considered the Osprey line with the adjustable arbors, which saves money by allowing you to use one laser bore sight for different calibers. But, the reviews indicated that hassling with arbors would have an effect on accuracy and reliability.
I almost got the Firefield, which seemed to have a similar number of decent reviews. Ultimately I decided against it because the entire line is made of an aluminum shell, and I think the brass shell of the Sightmark will hold up better.
It should be noted, however, that the 12 gauge Sitemark is made out of aluminum, unlike the others, and is only painted a brass color.
The biggest complaint against all of these laser boresighters are the frequent DOA batteries and poor battery life. The Sightmarks all come with alkaline button cell batteries. The small caliber ones (9mm, 7.62mm, .223) come with two AG5 batteries while the 12 gauge came with three AG13 (LR44) batteries.
To get you all confused, the printed information on the back of the packaging for the 7.62mm and .223 says you can use 3 AG3 batteries in place of the 2 AG5 batteries (since the AG3 is a thinner battery with the same 7.9mm diameter), while the printed info for the 12 gauge says you can use 2 AG5 or 3 AG13 batteries. This is flat out incorrect since 2 AG5 batteries are too small to fit into the 12 gauge Sightmark battery chamber.
Confused? Go to wikipedia and look up the article “List of battery sizes”. Scroll down to the section titled “Silver oxide and alkaline cells”. The table lists all the different names for each battery, their dimensions, and their mAh power rating. Note how the silver oxide batteries contain 1-1/2 to two times as much energy as the alkaline batteries.
So the key is to go out and get some silver oxide button batteries, size SG5 for the AG5 powered Sightmarks and SG13 for the AG13 powered lasers. And don’t go to your nearest retail store, since that will cost you an arm and a leg. Google shop for these batteries online. I found two Made in China “brands” one called Vinnic and another by Chung Pak Battery Works which were pretty cheap. The names aren’t important, since I’m sure they will change rapidly. Just remember to get some silver oxide batteries online at the same time you are getting these Sightmark bore sights.
How well did these Sightmarks work? The very first time I used one (the 7.62x39mm), I plugged in the included AG5 alkaline batteries and the resulting laser light was exceedingly weak. My initial reaction was that this was a bad laser. Then I remembered the silver oxide batteries I had gotten. When I switched out the batteries, the laser suddenly glowed brightly. Later, when this set of silver batteries finally wore down, the laser light faded again. That’s a sign to change batteries.
The larger AG13 alkaline batteries for…

|Cartridge Laser Boresight,
Excellent product in original packaging. This item works perfectly and is an excellent way to pre-sight in a handgun. Laser is bright and provides a sharp pinpoint to check initial setting of sights. Shipping was prompt and well packaged. Thanks.
