Bore Sight Kit Red Dot Boresighter Fit Any .177 to 12GA Caliber Firearm…

I have never used a bore sight of this type. I have to say it is easy to use, and when you have trued your sight weather it be a stock sight , red dot, or scope this little honey gets you true in just minutes... The directions are a little sketchy but it's not hard to figure out that you either have the batteries in correctly or need to turn them around and then just dial the knurled round battery housing to turn it on.... Once you have it turned on it's time to get to work.. I say work because if you are like me and not have an automated target return I have to walk down to the target and back to make my adjustments on my scope... But that's a small price to pay when you are counting on your scope for when taking aim... Good luck, and good shooting... P.S. : Be careful not to direct the light of the laser into your or anyone else's eyes...

I've never in my life experienced such a convoluted over-complicated way of putting batteries into something. After 10 minutes I gave up. You will want to throw it through a wall if you get this, and also be aware there are ZERO instructions on how to properly insert the batteries.

Works as advertised and expected.Nice being able to bore sight anything I want to.

Adapters are flimsy and should be labeled not easy for beginners and doesn't stay straight even with proper adapter...broke my .22 adapter first time used...sad but will be finding a different type of bore sighter
