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

Works great in both of the semiautomatic .22 rifles I have, a Marlin Model 60 and a Ruger 10/.22. The end of barrel type won't work with the Model 60 and this Sight-Rite worked great at putting it on paper and extremely close to the center of the crosshair and required only a few clicks to zero. Nicely made boresight. Just keep in mind that it's an electronic device and they tend to be a bit on the fragile side. That being said, it's best to put a Q-Tip between the bolt and the device, remembering to always close the bolt against the boresight by hand to avoid impact damage to the unit. Works fantastic!

Great Item - Great seller- Fast shipping

This thing is almost perfect. The laser is very bright and make it very easy to site optics, peep sights or open sights on a 22 caliber rifle. When the laser is placed in the chamber, the fit is secure keeping the laser pointed in a perfect direction out the end of the barrel. The battery life has been great and the unit functions exactly as you would expect. I would like to have seen longer lead wires going from the battery to the laser. Being short makes it difficult to hold it in place while adjusting sights.

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 😊

Item arrived on schedule and is satisfactory. Thank you

Simple to use, fits like a normal round. I used this on a 1961 Glenfield Model 60 22lr. After inserting into the barrel be sure to close the bolt carefully and do not damage the power wire. After using the bore sight the 1st round was within 3 inches at 75 yards. After 2 more rounds I was zeroed at 75 yards. I prefer to zero at 75 so I can plunk at 150 with ease. Ty

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.

not a true fit
