MidTenGreen Laser Bore Sight 223 5.56mm/ 9mm/ .243 308WIN Laser Boresighter with 4 Sets of Batteries

seems to be a ways off. but i don't understand how. because rotating it in the chamber doesn't change the impact point. so must be my understanding of it that's off. works great once you know the offset to figure in though. nicely built, and seems to be great quality.

Zeroed all my AR units. No issues or problems

Excellent piece to reduce fine-tuning. Works as it should.

Chambers well for accurate sighting. With the cost of ammo, this is a better and faster way to sight your weapon.

Purchase my first firearm which is a Walther PDP F Series and it came with an optic. Naturally I needed something to make sure the dot was accurate.This Bore sighter was my first option however I cannot complain about it at all. I purchased the green laser because my optic is a red colored sight. The shipping was relatively quick, and item worked excellent. I would recommend it to anyone thinking of purchasing a bore sight.

I like the green laser as you can sight in easier at range and in daylight than you can with a red laser. I bought both the 9mm and 223 bore sights and they both operate great. The one feature that is missing is an on/off switch. You have to take the batteries out every time you are done with the sight. On an outdoor range, you can easily lose the button batteries. Not sure how you could re-engineer it with a switch, but it would be a nice feature.

This is a close range sighting tool for low light. Not great bur not terrible.

Works well to line up red dot sight. Saves ammo.
