12 Gauge Bore Sight Red Laser Bore Sighter Red Dot Boresighter with 2 Sets of Batteries

Good quality. Works as intended. I would've minus 1 star because of no on/off switch; however, it was very inexpensive and it was a powerful beam so I give it 5. Just take the batteries off. It's really a one-time use; however, you can pass it along or keep to sight a new optic. I am very satisfied with the purchase.

Was skeptical about this at first, But it Zeroes exactly up to my already-zeroed iron sights at 50 with slugs, then I just adjusted my new red dot as needed to align with the laser bore sight on my mossberg built in usa. But the laser was wobbly in my turkish shotgun, and couldnt get zeroed til I placed a rubber o-ring on the laser to fit snuggly in the chamber, they milled out the turkish chamber bigger than regular specs I bet, not the laser’s fault. So it works on good quality shotguns, just not cheap imported shotguns.

This is a well-made heavy aluminum laser sight. The R44 battries are a big plus because they are inexpensive. Note that there is no way to turn it "off "......You must remove the batteries. For the price, this unit gets a 10+ !!!

Simple to use....worked as advertising.

I bought this to bore sight my auto shotgun. I bought one of these before for my AR-15, and it's definitely worth the money. You can literally adjust your sight picture in your living room.

Is there a 0 rating..Who makes this item without an on off switch..$15 wasted..Went right into the garbage..wow unbelievable RIPOFF !! SHAME ON YOUR COMPANY !

It works but no off button get out of here

The back is solid steel/metal, there should be moveable/rubber/sprint spot on the back to hit the pin and not to let it demange, I beleive its not for Dry Fire, it would break the Shortgun's pin! Overall quality is good but I woudl say to Seller to please mention in the product description that its not for Dry Fire. Just recevied and planning to return it today!
