StrongTools Red or Green BoreSighter 177 to 12GA Caliber Rifle Scope Handgun Hunting Red/Green Dot Boresight Kit Press Switch Bore Sight 800mAh Battery

Works perfectly, easy zero, easy storage, fits most calibers, pistol and rifle, just buy it, it is 100% worth it. "Not a paid promotion"

Inexpensive, simple but well made little kit that makes basic initial bore alignment when first mounting a scope on a rifle or pistol fast and easy. Works well, nice case, and includes a complete array of plastic bore-centering adapters to fit almost any caliber rifle or pistol, including my .177 air rifles. Well written instructions, even includes a CR2 battery AND a spare. Five stars for quality, value and utility.

Let’s start with the obvious, this unit is cheap. Relatively speaking a round of most rifle ammo can be close to a dollar, and even pistol rounds are fifty cents plus for match grade. If you can eliminate 5-6 shots from your usual zero SOP you just saved some dough ray me. I haven’t had a true opportunity to take this to a range, but have three new pieces and one is missing a front sight (ordered) I want to make sure they are all up to our standard and zeroed and ready to go. The way I tested this was I have 3 known zero weapons, hand gun, bolt action Rifle and AR platform. I installed the bore laser in each of them and they were all within 1-2” at 30yds and the bolt action was dead on although the laser is pretty large diameter at 30-50 yds so getting absolute zero will take additional effort beyond the bore tool. With the AR platform the muzzle device seemed to add variations as I turned the laser in the bore, for truer initial set up I would recommend removing the muzzle device. And if you have a can on this likely will only help with left to right variance and not drop. Bottom line this was very inexpensive compared to most high end models, the bore plugs are not well marked and are small plastic pieces. Likely you will only use this for initial setup of new optics or after a swap, possibly to align handgun sites after changing etc. This unit came with 2 batteries meaning it shipped with a spare that was nice, the bore plugs are numbered but the numbers are 1-2mm in size on molded plastic (barely visible) plugs are colored so maybe long term it becomes more intuitive. Green laser is extremely bright at 10-15 yards it is great, out past 30-50 and the laser beam seemed pretty large it dwarfed my bolt action steel open sight post, and on an AR 3x optic with 4 MOA center dot it was larger than the dot so absolute zero would be impossible but it would likely get you to within 3-4” groups before you needed to start sending rounds down range.

Item works very good all you need in one box,

I recently bought, reviewed, and returned the LaserLyte competitive product. I knew what kind of tool I wanted and bought the most expensive version of it in the belief that it would be the "best". After returning the LaserLyte, I decided to try again with the Strong Tools boresighter in green. The price was approximately half that of the LaserLyte. In comparison: 1. Strong Tools boresighter comes in a nice plastic case that closes tightly and has a properly fitting place for each component of the kit. LaserLyte comes in a fragile foam sleeve with no place to keep anything. 2. The instructions for Strong Tools, while containing grammatical and typographical errors, are clear, and there is an explanation not only how to set the sighter up, but also how to use it. LaserLyte was incoherent with illustrations that were useless, and with no advice on how to use the tool. 3 The Strong Tools sighter has an on-off switch. The only way to turn the LaserLyte off is to remove the three fiddly little batteries, which are prone to falling out of the uncovered recess anyway. Also, Strong Tools uses one single battery (and comes with a spare). 4. Both the Strong Tools and LaserLyte have multiple plastic inserts for different calibers. In the Strong Tools kit, the adjustment screw is already IN the plastic insert and ready for use. The LaserLyte screws and plastic inserts are loose in a plastic bag, and the little screws DO NOT FIT THROUGH THE HOLES in the insert. I note (retroactively) that this is a common problem with LaserLyte, and many users report having had to drill the holes in the plastic inserts to get the screws in. The plastic inserts are extremely fragile and seem prone to breakage while doing the drilling, which you would think would not be necessary anyway. I did not find out, because after taking 20 minutes to figure out how to power up, and 15 trying in vain to get the screw through the insert without breaking it, I returned it (the LaserLyte). 5. The green laser was bright and easily visible both through the scope, and without, at the 50 yard measured distance at which I was sighting. In an hour, taking my time, I had sighted or resighted two 22LR rifles, a 221FB handgun, and a 22-250 rifle. It was easy as could be. I was working outdoors in cloudy daylight and there was no problem in seeing the lasers. For each weapon sighted, I would match the scope to the laser dot, then remove the sighting tool and replace it and resight to see if the laser point of aim was the same. It was not, but the variance was only about 1-3 clicks, mostly windage. This gave me confidence that the Strong Tools is working consistently. 6. I have not yet fired any of the guns, so I cannot yet say if "consistent" is matched by "accurate". However, one of the rifles sighted was an extremely accurate Brno Model 1 with a Leupold 2-7 Rimfire scope that I knew to already be sighted properly. The StrongTool laser and the scope crosshair were almost perfectly aligned on the first try, so I am optimistic that the other three will be "on the paper" when I start the firing tests. I almost gave up on this type of tool after my experience with the LaserLyte. I'm glad I did not, though I'm glad I gave up on the LaserLyte. At half the price, the Strong Tools option is the best. In fact it would also be the best if it were twice the price of the LaserLyte. It would also be better even if the LaserLyte were FREE, assuming that you want your tools to conveniently accomplish what they were designed to do. I do.

The red laser works well indoors. I tried to use it outdoors and the red laser dot is not visible beyond approximately 12’.

This is one of the easiest boresighter I have used, very simple to set up and the IR's point of impact stays fairly consistent in relationship to the barrel. A lot less cumbersome to use than a traditional optical boresighter and certainly more precise than the cartridge-shaped ones, which are dependent on how they sit in the chamber. Definitely a time and ammo saver, it is a bonus that it can be used across different calibers with the appropriate adapters. Seller is also very responsive in replacing a missing adapter.

Ease of use good quality

Depuis cet achat, toutes mes armes et celles de mes amis sont faciles à calibrer. Il y a des embouts pour tous les calibres. La seule critique vient pour l'ajustement d'un calibre 12 (50mm) où le canon est vrillé pour la "slug sabot". Il y a un tout petit jeu qui peut faire perdre de la précision. Il faut simplement "s'armer" de patience et voir à ce que l'appareil soit bien fixé. Aussi, le laser VERT est plus visible que le rouge, surtout en journée. Cela a été testé à même un champ de tir avec un grossissement 1X :... 25 mètres (très très visible) - à 50 mètres (il faut être attentif). Avec une lunette de visée de 3,5 à plus, le point vert est très facilement repérable. EXCELLENT OUTIL DE CHASSE. Assurément, vous vous ferez des amis!!!

i expected it to be both red and green however it is only red that being said it seems to be well made and accurate but it will only show to about 40 yards possibly poor batteries i would have liked use it at 100 yards

This boresighter was well designed. It has excellent accuracy and consistency, and is mostly easy to use. The accuracy is proven by using the boresight multiple times, with the product being rotated to different posiitons for each test. The laser dot does NOT move on the target. It stays in one spot, which means that the boresighter is truly concentric with the firearm's bore when installed correctly. It is mostly easy to use, with one exception: Any "labeling" on the inserts that customize the device to each specific actual barrel bore is too tiny to actually read, even with a magnifying glass! But I got around that by simply starting by trial fitting inserts that were just a bit too visibly large, going smaller, until I got an insert that would insert into the bore (BEFORE being expanded), and then using the provided (!!) tiny screwdriver to enlarge the insert's diameter by tightening it a BIT at a time until it would JUST slide into the bore but NOT be sloppy at all. That made the boresighter PERFECTLY truly concentric with the bore, as evidenced by the styability of the laser dot on the target no matter how the boresighter was "clocked" in the bore. I imagine that if you use TOO small a base insert and then expand it, there might be some flexibility possible due to the (necessary) rubber composition of the inserts, so don't do that. Use the largest base insert that will fit into the bore before being expanded. This kit is unusually complete too, including TWO batteries (one is a spare!), the tiny screwdriver, and a really nice case to keep everything safely, and nicely, stored. The red laser light is VERY visible. Highly recommended.

Very impressed with the green laser. I have bore sighted a lot of rifles but when it comes down to ones you can’t this is very impressive. Laser at 40 yards was very bright at the range. I had no issues sighting in my rifle, just wish I would have found it sooner to save on ammo as this is so easy and convenient to use that it takes the guessing game out of it.

It seems to be ok to get your first shot on paper. Use a large paper. At only 20 - 30' and in a bench rest, you can spin the laser and make a 1 1/2" circle on paper. That may equate to the accuracy of a hand grenade at 50 yards. I suspect that rotating it to the top or bottom of the circle will sort out the vertical aim. Yes, it fits tight in the barrel.
