Sightmark .17HMR Boresight with Red Laser

works great very small laser point for good sight zeroing ability at longer ranges without blowout

This little boresight is awesome! You have to take your time and be patient. I placed it in my Savage Arms to sight in my scope and it is a little difficult to get in and out of the chamber, but patience is a virtue. Once I got it in and placed the laser on the bulls eye at 25 yards, sighting in my scope was a breeze. I used it to sight in my new Nikon P-RIMFIRE BDC 150 reticle scope and had it sighted in at 25 yards in 2 shots and less than 10 minutes. I spent more time putting the boresight in and removing it than I did sighting in the scope. The laser is bright and easy to see at 25 yards. I will be using this to sight in another Nikon scope on my Ruger 10/22. Well worth the $, and although I have not used the mini boresight that looks like a thermometer, I can say that this type seems easier and more accurate to me if you just need a boresight for .22 LR or .22WMR. I like it. You have to be careful not to pull on the cord or slam it in the action when placing it in and taking it out but like I said, "with patience", it works great.

Bought this to sight in a .22 LR. The first one I got was used and broken. It looked like they accidentally let the breech close on the wire. It should always be locked back when using. This bore sight gets you very close and to zeroing. It sits a bit loose in the bore, which requires holding it centered in the bore. I like it and use it whenever I zero in my .22’s.

works fine on a 10/22 RUGER has good battery life easy to load in and mount adjustment good sights were almost dead on at 200 ft bright laser

Is simple to use and protect the wire. This works for any laser boresighter whether it has a wire or not. Cut a small bit of cloth rag. I used an 8" x 6" piece of a pair of athletic shorts. For larger caliber & wireless sighters a much larger rag can be used. Lock the bolt back. Put the sighter in thru the ejection port. Roll the rag & push it up thru the mag well. For wireless sighters you can jam the rag in through the ejection port. Slowly (very slowly) let the bolt compress rag against the the sighter. Push the rag toward the far wall of the receiver so that it doesn't stress the wire but securely holds the sighter in the chamber. (This step doesn't apply to non-wire sighters.) I wasn't impressed with the storage case - I think it is it too small and will stress the wire to use it. (But it is a good size to put other wireless cartridge type sighters in.) I very carefully opened the package so I could store the sighter in the clear plastic it was packed in (with the sighter appendage part removed).

The best I have used. Far more secure than the end of barrel type. Gets you close and priced fairly. Bright, and no tiny watch batteries. Very nice.

I tried the magnetic kind that go outside the bore, (don't bother wasting your time on that! They scratch your gun, overpriced, and inaccurate). This product however works great, it is plug and play. It does seem to aim high, but I don't know if it's due to bullet drop or physics. Aside from that, side to side it is centered, and I like that you can turn it on and off by the switch. I would have liked to have had a thicker cable, but I haven't had any issues. I tried cheap laser sighters, I tried really expensive laser sighters, and they all failed terribly. This is the one that was just right in terms of consistency and functionality. I wish I'd tried it first, it would have saved me a lot of time and effort!

This is a decent tool to have for sighting. I've used this on a couple of rifles and it seems to be pretty accurate for the most part. (Meaning I was able to get the rounds on paper in the black but not close enough to zero). I haven't been able to take the rifle to the outdoor range to verify the sighting at 25/50/100 yards as I've only shot it in an indoor range at 15 yards, standing with no bench rest. The only big issue I have with this unit is that it fits really tight in the barrel. So you will need a rod to push it out. Don't try to pull it out by the cord, otherwise, you'll completely destroy it. Also the bulking power supply is a real pain. It gets in the way if you need to move or pick up your rifle. I ended up just strapping it to the hand guard with a rubber band. And like the other review, the laser does stick out and prevents me from closing my bolt.

Das Teil war eine grosse Hilfe.

Spedizione amazon come sempre conforme agli standard. Boresight SM39021 semplice e pratico da usare consente precisa taratura sia per pistola che carabina il prezzo ritengo sia elevato ma attualmente no si trova niente di meglio qualità 4* prezzo 2*. Comunque fa quello che deve fare

👍😊😊

Works as expected. Boresighted my .22s with this. Did the job. Laser is strong enough for bore sighting. The connection wire from the battery pack is thin, it has to be handled gently. A gentle tap with a finger and the brass laser holder will stay in the chamber.

works to get you on paper but you still need to adjust scope to sight in the rest of the way. may save some ammo but not enough to offset the cost for 22LR ammo
