SME Sight Rite Durable Shooting Hunting Accesories Bullet Laser Bore Sighter | Batteries Included

Great product, easy to use and accurate.

Pretty cool device,,,didn't know it existed, works way better than the kind that stick in the end of the barrel. In my opinion, much more accurate.

Just received the 22lr version in the mail. I put it into my Vudoo which is already zeroed, and the dot will move a good bit at 20 yds as the laser is wiggled. Note a Vudoo has a match grade chamber so not a result of a large sloppy chamber. Found that if I move it and watch the dot move on the target was able find the middle of the movement and lock it in place by snugging the bolt against the laser. This put the dot very close to my windage zero. Bottom line when the new rifle and scope arrives, I will be able to get it on paper at 25yds to get started with a zero. To be honest that is what I need. An interesting other point is the URL suppled to register it for warranty does not work. Yes, I verified that I typed it correctly.

works perfect, no complaints.

Works just as expected. Finding a light for 22cal bore is not cheap but it works. They shipped fast but as usual USPS is not the fastest.

I bought this for my first rifle with a scope, if only to attempt to get a good sense of where my boreline is landing downrange, and perhaps save 10-20 bullets.What I got, however, is an imprecisely "bullet-shaped" laser enclosure attached by a flimsy minimal-gauge wire to a somewhat less-flimsy battery+switch compartment.The tolerance is far too wide. My caliper indicatess .2215 for a federal 40g HV round, while this "bullet-laser" registers a .2195. Even a seemingly small play of .002" at the breech multiplies it's inaccuracy at every distance.There is so much play in the barrel (as this is a bull-barreled target rifle with finer tolerances than the standard 10/22) that my initial setup @25 yds exhibited play/wiggle of ~ 6" at the target. This occurs while attempting to seat the 'bullet'-laser in the breech-end of the barrel as well as it can fit.TL/DR: IT DOESN'T FIT because the tolerances are too wide.I suspect that this would translate to a dreadful MOA when attempting to zero with this @50-70 yd - possibly something in the order of a ~25+ (!) MOA. I don't care to find out....I should not have bothered. I'll just have to shoot more groups at 10&25yd and and zero my scope to 50yd the traditional way.

10/22... The ubiquitous Ruger miracle. I've enough of them to know that they are not precision built, and the chamber is a hit and miss at best. We're not talking VooDoo here. So yeah, this little laser is like an undersized bolt in the wrong size nut. You... get the picture...But what if (and I did) you put some sort of “condom” on it. At first, I thought I wrap it up in 5mil rubber glove (pinky) but that would have made it impossible to insert - too much friction. Then, I came across Scotch 3M Magic Tape - it's 2.5mil thick. So wrapping it around the boresight laser adds total of 5mil to diameter. And you know what else it does also? STAYS PUT IN THE CHAMBER LIKE NOBODY'S BUSINESS! The Magic tape's UPC is 34-8724-6004-2 - nothing fancy, just straight run of the mill (mil, sic) tape.Once I enveloped the laser in the tape, it fit snugly in all of my 10/22s (I'll keep the number to myself as not to reveal my 10/22 insanity). Tomorrow I'll also test it on the rest of my 22 buddies (The HKs, the Brownings, GSG, Mr. Henry, Wather, Winchester, the Savages, the Rossys, Heritage, Taurus, Blueline (Mauser), the Bergaras, the CZs and my two friends Mr. Smith and Mr. Wesson). Some of the CZs, Browning, Savages, maybe Mr. Henry and for sure one of the Bergaras are precision match chambered (bentz chamber), most likely, so in those cases, I'll take the tape off - got knows I have plenty of Magic Scotch tape.Anyways, prior to this little trick, I was seeing pretty much what every disgruntled reviewer of this little laser saw. But again, an under $500 10/22 is meant to "eat" most anything you through at it - don't expect a tight chamber. And Ruger's been known to set their stock firearms to the widest possible margin of compatibility (Mini14 anyone?)Bottom line, this laser gets me within 5” at 50’ and 3 at 25’ for guns. I can take them all to surgical precision, where possible, from there. So for under $30, yeah, sure, I recommend it. Even though with 22lr prices coming down to .04-5 you actually might have more fun just walking it in.. At any distances 😊

Pros: Bright. Runs on AA batteries.Solid fit in the Ruger 10/22 and Grandpower K22.Solid connection between power cable and laser.Cons: Small connector cable between battery and laser.Loose fit in the Marlin Model 60 SB.Overall, the laser cartridge and design is good. Unfortunately, the 22LR rifle this was purchased for shows laser drift due to weak alignment in the Marlin Model 60.
