Thank you so much , I just purchased a sight mark and will be sighting my rifle for the 100 yd mark. Like many comments your video is very clear and one of the best illustrates this product . Cheers 🇨🇦
Watched this for a re-fresher, been quite a while since I used mine. Getting ready to sight in a new AR I built and haven't used it for 5-6 years at least. I agree, this is just to get you close, too many variables like you said. I actually cut some small round thick paper to put in the battery compartment, between the battery and screw on cap. Got it out today and it still worked, I'm shocked the batteries weren't dead from the length of time it's been sitting in the safe. Thanks for the video.
I have seen other videos on these products and one of them the person marks the ( iron, reflex, scope) sight aim point on the paper target as a reference point after that they made a ( small dot) mark on the laser bore sight and turns the bore sight in 4 positions 12,3,6 and 9 o'clock while maintaining sights with reference point. Mark each of the 4 bore sight positions on the paper target and use a ruler and draw a lines 12 to 6 and 9 to 3 using the 4 dots then zero in on that center point that should help overcome the imperfections in the "laser bullets".
That was a fair and accurate review in my opinion. I myself utilitized the 9mm version for my carry gun, which has an trijicon SRO on it. I thought "oh simple, just match up the red dot from the boresight and the red dot and I'm good to go." NOT. As I used it for several pistols I noticed all my red dots or lasers were way off according tot he boresight. Hmmm. So I went back and checked the first one I'd just lined up, and it was way off. And the same store on the next gun and the next gun. Very disappointing and I feel their packaging should be a little more clear of what the user can actually expect from their product. I mentioned it to my gunsmith and he said "oh , yeah, don't be your life on those." Thank you Mr. Desert Dog for the review.
Thank you - Your instruction on the use of the boresighter is spot on! I especially appreciated the tip about setting the crosshairs about 2” above the laser dot as I can see this will allow for scope distance from the barrel centerline. Thanks again. 😃😁😎 and of course I have the Sitemark in 243 Win.
many thanks for your video but I have never knew what to do with my hunting riffle, many times I missed my hunting, now I know and will change my way of using, I just use it from the gun store and never accurate my target, thank you for teaching and showing this
I bought a sight mark . It comes with the laser connect by wire to a battery pack. It has an on and off switch. Worked great. . I guess the battery life complaints were heard
Good basic instructions. Red in low light, and now there are green for daylight levels. Use his target references and adjust it in you house to those measurements and you will be closer to zero than you'd expect. Of course that brings math in to the house wall measurements. Well done Desert Dog! Always shoot Paper First!
I used to just eyeball it down the bore, you'd be surprised how well it works. But, my eyes aren't what they once were, and this little devise works well for getting your first shot on the paper.
Thanks for taking the time to publish this video - great Job in that it was very well produced with the pertinent info upfront, localized, to the point.
Great video - thanks - I just ordered one and will be here Wednesday. You won’t believe but I’m using with it a New England Firearms Single-Shot break-open and Vortex scope. I’m a scope beginner so should be fun. Thx again👍🇺🇸
Thank you for that video that was very informative because I'm getting ready to go to the range myself and zero my scope on my AR15 and I have that type of bore site or one similar
Seems all the ones like this I've used are always to the right about 8 inches at about 20 ft. Like the shell extractor pushes the cartridge to the right some.
I just purchased two for .223 and .308. The .223 laser beam is not concentric to the cartridge and unfortunately the calibration set screws are crazy glued in. If they weren't, people could make adjustments themselves by putting them into a drill chuck and turning the micro-screws until the laser light was concentric inside the device thus eliminating the famous crescent half moon people are experiencing from the beam reflecting off the barrel bore.
Take some blue painters tape and lay out the batteries on it and fold it over, leaving a flap to help open it up again. Or you can stick the tape on the inside of your carry case. I have the 9mm and put everything in an old translucent plastic 35mm film can. That protects everything from water getting to it.
Ok… i have a question. Before i drop a bunch of money on a bunch of different boresighters for a bunch of different calibers i need to know. I understand a specific boresighter fits the chamber of your firearm. I understand you have to chamber the boresighter in the firearm. I bought one for my .308 M1A. The package says it fits .308, .243, and 7.62x51. Now I get that it would work on both the .308 and 7.62. What i DON’T get is how it chambers tight in a .243 AND .308. They are 2 completely different case sizes so the chamber has to be a different size. Please advise.
odd question. what if you tried to bore sight it at 100 yards? if you were able to see the laser do you think it would be closer to zero? I don't even know if anyone's ever tried it or would even be able to see the laser that far.
They are fragile and the laser will not point true if dropped. I made a mistake and used it at a100 yard sign and bullet hit way low at 100 yards so learned to use it at 25 yards. Apparently it works inside the house too
I just received my Sightmark 9mm boresighter, and my initial assessment is it's the most accurate 9mm laser I've tried (and I've tried a bunce)--but since I have an RMR, a combo laser/light and suppressor height sights, I can still see that it's a few inches from being perfectly zeroed (it's a tiny bit high and about 1.5" to the left). Has anyone used the tiny screws on the top to fine-tune the point of aim of this laser? Since I can vice mount this to keep it perfectly steady, it sure would be nice if I could refocus it to be exactly zeroed with my irons.
THIS GUY TELLS IT MORE LIKE IT IS THAN MOST I HAVE SEEN-----ALSO TO MAKE THINGS EVEN FASTURE MOUNT A LASER TO THE SIDE AND SHOOT ONE BULLER___THEN ALIGN THE LASER TO THE BULLET___ THEN ALIGN THE CROSSHAIRS TO THE LASER____ONLY TWO SHOTS AND YOUR ON THE MONEY.
the only purpose of these is to bore sight the gun so that you somewhat on the paper before you go to the range and finish dialing your scope in. In other words, the bore sight is simply to save you your initial shots when at the range. and by the way, that gun is a tack driver!!!
This may be a stupid question but will these work no matter what your height over bore is? For example if you had a riser on your weapon giving a significant lift to your optic?
Yes. they simply point straight down the barrel to get you on paper before you go to the range and do a real sight-in. These are to get you on paper, not to zero your gun.
@@desertdogoutdoors1113 Roger that. Ok so that being the case would you say you'd be better off spending less money on a cheaper version? For example, the sightmark one is listed at almost 50 bucks but I found one by tacticon armament for like 15 bucks. Just buy the cheaper one since it's just a tool to get you close? They operate in the same way as near as I can tell.
I recognised that they are damn canted? Everytime i put the 9mm variant inside it puts the laser dot on another spot! Same for my 223 and 7,62x39 boresight! Pretty inaccurate, cant really recommend them
I've used these for the glock g35 and it is really bad. I had to adjust my adjustable sights all the way left and the laser says its still not needs to move more. Will have to just try at a gun range.
I bought one of these and the laser is not visible through the bore. Does anyone know if there are adjustments screws or another way to troubleshoot? Thanks
@@desertdogoutdoors1113 I thought about that but it looks like the light comes out like a half moon line it is hitting an obstruction in the bore or my muzzle device
An unnecessary expense in my opinion. Why not simply place the rifle in solid bags, remove the bolt, place a red target dot at 30 yards. Manipulate the rifle in the bags until the red target dot is dead center of the image created by looking down the bore. Then look through the scope, turn the W and E turrets until the crosshair aligns with the dot. You may have to readjust the sight picture through the bore a few times to fine tune it but with a little care and concentration you will can fire a shot at 30 yards and be within an inch. Just my two cents.
I get they're not "perfect" for setting your aim... but let's use mine as example. .40 S&W. Laser isn't even set to zero in the brass, causing the laser dot to move more than one inch in a 5ft distance. This is a BIG reason to steer clear of these boresights.
I’d somewhat disagree with you. If you take the laser out to the range and sight it out to the range you desire it can put you dead on. Going to my local range at dusk I could get out there pretty far. I used a higher powered laser I got my hands on. Nice video though.
Good video. BUT, why would a laser (which is used in many application for highly ACCURATE measuring) be less accurate than a group of rounds that may be affected by conditions.
Short answer = because the laser is housed inside a case of "generic" dimensions and is manufactured cheaply. Long answer = these laser boresighters are made to fit "cartridge families" rather than a particular cartridge. Most cartridges (even most belted magnums) headspace off the shoulder, and since these laser boresighters are a one-size-fits-all item, they will most likely be a sloppy fit in the chamber, particularly without a bullet helping to align the cartridge with center boar axis. Also, these cheap Chinese items are NOT made to exacting standards that precision military and industrial equipment is made to (really no better quality than a cat toy). Sight in you rifle with one of these, then shoot a target at 200 yards and you will see for yourself.
@@desertdogoutdoors1113 Thanks, that does make sense. I was thinking along the line of barrel ballistics as opposed to the actual center of the bore-even if the sight WAS right on it would not make that that the actual hit point of the rounds.My rounds have been surprisingly close to the sight; but they still did need dialing in, a bit.
Great video! I just changed the sights on my 9mm, Glock 19 (night sights), do you have any advice on using this on a handgun? I never done this before and would love to know your thoughts? Currently shooting low left at about 7 yards. I want to hit targets at a much farther distance... Lol.
...don't bother mentioning the fact that you have to buy a dedicated bore site for each caliber you plan on using. ....multiplying the COST! hhmmmm.....no thank you.

You do understand that this is to get you on PAPER so you can sight in using the ammunition you will be shooting on the hunt, I hope.
Thank you! It’s the best, detailed and very honest sightmark review I ever watched.
They get you close every time. Bought one for my 10/22 today and it got me about an inch off at 100 yards I got lucky.
Great quality product.
Best way I've ever heard it put. Use it to help get it close. Then fine tune it at range.
many thanks for your video but I have never knew what to do with my hunting riffle, many times I missed my hunting, now I know and will change my way of using, I just use it from the gun store and never accurate my target, thank you for teaching and showing this
It looks like you could do your initial zero against the bore sight at a distance longer than 25 yards, based on the strength of that beam
I bought a sight mark . It comes with the laser connect by wire to a battery pack. It has an on and off switch. Worked great. .
I guess the battery life complaints were heard

Dead on. I have several, and to your point, I use them to get in the "ball park". I save a lot of ammo...
Hi here down from the Netherlands 🇳🇱… thanks for outstanding explanation, nice video !
I just flip the first battery upside down and leave them in the laser.
Good video, I have one for my .300 WM and use it only to not shoot in the other targets ;)
An easy way to store the batteries is to put the second battery in backwards and store in the bore sight.
hey this was actually really helpful. thanks!
Thank you for that video that was very informative because I'm getting ready to go to the range myself and zero my scope on my AR15 and I have that type of bore site or one similar
Short but very informative video. Looks like a Sightmark laser sight tool is in my future. Nice job..thanks.
Seems all the ones like this I've used are always to the right about 8 inches at about 20 ft.
Like the shell extractor pushes the cartridge to the right some.
Mine came defective. When you insert it in the chamber, the laser becomes distorted. When out side of my rifle in my hand the dot looks fine
Thank you for a very concise and informative video.
Of course, note the kitty on the right hand side of the field of view, starring at the red light. LOL. Thank you!
I just purchased two for .223 and .308. The .223 laser beam is not concentric to the cartridge and unfortunately the calibration set screws are crazy glued in.

Where I work we tell the customer it is sighted in to hit a Paper target at 25 yds, you have to do the finale adjustments yourself.
Good info. I just purchased one. Gonna try it out . Thanks.

Thank you very much for you advice I learn from you something very interesting that I didn’t know about this.
I used it an bore sighted my 300 WM.At 1 inch high above the red dot at 70 yards I was almost dead on at 160
Great video, please keep up the good work.

How do you remove a the boresighter from barrel without disassembling the firearm?
You eject it from the action.

I got this for my 44 mag, it was horrible. The laser was not zero in the cartridge. Put it in a cradle and it made a 2 inch circle on the wall.

Ya know i'm good with this video too.
Lost count
I store my laser boresighter with one battery turned upside down, So when I need to use it, all I need to do is flip the one battery.

Like the packages says “Bore Sighter”. I don’t understand why anyone would think these “zero your rifle scopes” 🤦🏻♂️
I recognised that they are damn canted? Everytime i put the 9mm variant inside it puts the laser dot on another spot! Same for my 223 and 7,62x39 boresight! Pretty inaccurate, cant really recommend them
These things should have a pressure switch that gets pressed when chambered but I guess that's too simple.
I agree
I've used these for the glock g35 and it is really bad. I had to adjust my adjustable sights all the way left and the laser says its still not needs to move more. Will have to just try at a gun range.
Check your trigger pull
@@Charlie-xs9kb lol my thoughts exactly
So does the boresighter have a lip on it so you can eject it or do you have a heck of a time getting it out ?
Ejects like a normal.case when the bolt is pulled back.
I bought one of these and the laser is not visible through the bore. Does anyone know if there are adjustments screws or another way to troubleshoot? Thanks
Perhaps you need to use it in darker lighting conditions.
@@desertdogoutdoors1113 I thought about that but it looks like the light comes out like a half moon line it is hitting an obstruction in the bore or my muzzle device

I keep seeing mixed reviews, some pistol shooters delighted with these, and some are "ehhh, it doesn't fit".
excellent
Sounds wonderful, too bad they do not aim the weapon well.
i think you used 6 rounds to sight that rifle in not 3!
Mine I just got is like 3 inches to the right in my glock 17. Garbage
All it's meant to do is get you on paper, so you can properly zero your optic. It seems like it did that.
These are garbage.. laser is not close at all
...don't bother mentioning the
fact that you have to buy a
dedicated bore site for each
caliber you plan on using.
....multiplying the COST!
hhmmmm.....no thank you.
Still saves money
