MidTen Bore Sight Laser 9mm/223 5.56mm/30-06/25-06/270 Laser Bore Sighter Boresighter with Batteries

Great iron sights alignment tool and for setting up a red dot. no on or off switch, just pull out included batteries. works great!

Worked great in my Legion. Maybe I received a good one or QC has improved; there was no slop in the 9mm chamber. I removed it just to put it back and check and the dot was still on. $17 is too much. Wish I tried the longer $10 one to try.

Works perfectly. Easy to use. Saves lots of time and ammo. no way to turn off except remove batteries.

The Bore Sight was package well and the batteries were easy to install and an extra set of batteries are included. I used the .223/556 bore sight in my house to adjust the scope, a very close range. At the range the drift was off about 1.5" but the elevation was off 12-14". I think the elevation would have been closer if I used more yardage when bore sighting but I got it on paper. So, now I know what to expect when home bore sighting.

Great product fit perfect, feels well made not cheap. Batteries are included would highly recommend.

The MidTen 9mm Bore Sight Cal is functional and does what it’s meant to do, with a few limitations to be aware of. I used it to help zero a red dot on my Canik TP9 Elite SC, paired with a Holosun optic. As a starting point, it works well and realistically gets you about 90% of the way there before heading to the range. The laser is bright enough to see clearly indoors and makes initial alignment much quicker. That said, there are some downsides. There is a bit of play once it’s seated in the barrel, which limits precision. Battery life is also fairly short, and since there’s no on/off switch, you have to unscrew the unit and remove the batteries for storage, which is inconvenient. Overall, for the price, it does a decent job and is helpful for rough sighting and setup. Just don’t expect it to replace live-fire zeroing. Useful as a tool, but with clear compromises.

Worked great. Great value.

Got a new cow glock and had also paired it with a micro red dot. This helped me to quickly load the chamber and focus my red dot on the red laser from a 30 yard distance. Easy to set and configure. Be sure to use blue loctite though. I missed this step and my glock began loosing proper sights after 150 rounds give or take. Turns out the screws where self loosening from all the shell ejection vibrations. Lesson learned. Save yourself from damaging good sights. Easy alignment is as expected. Excellent build quality. Easy to install batteries.
