BoreSighter for 22LR/223/9MM/7.62X39MM/30-30/30-06/.25/270/243/308/7MM/ 45ACP Colt Caliber Rifle Scope Handgun Brass Red Dot Boresight Kit for Hunting with AG3 Batteries (Special, Bullet Type)

First time user, friend suggested it as he has one. Works great and easy to do.

Bear bore sight so far. Protective case, most others once opened find a way to protect. Adjustable O rings for a secure end of barrel sight alignment. Keep in mind, a bore sight will get your optics aligned to get you on paper when zeroing your sights. Battery holder is great. No wrappings to remove. Batteries are not touching to prevent a slow discharge of power. HIGHLY RECOMMEND.

Have used to preliminarily zero .22lr & 9mm red dots. Bore sight worked well requiring relatively small adjustments at the range. The barrel fit was snug and 0-rings are included if necessary. Tiny batteries are a bit of a pain, but all in all a good tool.

The boreSighter is amazing.. It save time and money!

simple but functional. i used this to test out a new laser sight. it worked well. the fit int he .22 barrel was nice and snug for excellent alignment. i had another one years ago that slipped too much to be useful - this one is good. i apprecaite all the extra batteries and the extra o rings to keep things tight.

Worked perfect on a stock ruger 10/22. Works great, gets you on target very quickly.

Does exactly what itvsays

Decent product. Appears to be made of brass. The lazer diodes are bright. The .22 centers on the muzzle w o-rings, several different sizes are included for slightly different bore sizes. The 9mm appears to center off the headspace in the chamber. I centered 2 pistols and a scoped rifle in about 5 minutes. Using a bore sighter is a great and quick way to get sights on target wo using any ammo. Obviously final adjustments require actually firing the weapon but it can cut the amount of ammo u need to burn to get new sights on the paper in half. Its best to use bore sighters at a known point blank range (a distance before the bullets path is changed by physics). I used 15 yards for the pistols and 25 yards for the .22lr. After point blank range the lazer will become inaccurate as light has less mass than lead. That being said the lazer is easily visible at 50 yards.

This was a very well loved gift for my husband. He says they work very well. It was impressed !!. Sights perfectly. The product was exactly as described in the item description. I live in Canada and the parcel arrived at my door in less than a week. I find that to be decent shipping speed. I would recommend this product to my friends and family. I would definitely buy again!

Would have liked a switch on the cartridges, but it is a very good deal for the price. Plenty of batteries included. The customer service is very quick to answer and react. I had a small issue and it got resolved within 2 days.

9mm too long to eject,223 fits good did not try others yet

A-1

Used a few of the calibers and they worked fine with the exception of the 9mm. Laser failed to work after one use.
