ADAFAZ Bore Sight Kit Red/Green Boresighters for .22 to .50 Caliber Pistols Rifles Bore Sighter for Hunting

Bought this on because the laser was adjustable so you can find that true bore axis. Didn't need to do any adjusting because it came pretty zero out to 50yards! Don't listen to people who say they shot 5feet of at 20 foot range or that it was so off at 100yards because they ate too many crayons. Also the reason it isn't tigh in the berral is because you need to insert and twist clockwise in order to tighten the screw and expand the rubber insert to fill the berral. Most of this stuff is on the instructions and is common sense.A good way to make sure you have the correct bore axis zero is to turn the device snugly in the barrel and look for it to circle around. It is nice and zero when you turn it and the laser doesn't move.As far as ballistics goes I have pages long of fun formulas but here's a good trick. Find the ballistics for your bullet and say your going to sight in at 100yrds. Find the bullet position at 25 yards mine with a 2.825" scope height(bullet starts at -2.825") is -1.9". I then pluged this in to est angle (tan^-1(1/[25*3*12])) and got 0.06366°. Then I plugged in tan(0.06366)*50*3*12=~2" so I know at 50yards I want my optic to be 0.825" above the boresight and I want my shot group to be 1" below my optic according to ballistics data. This makes it so I use as little ammo getting that zero at 100yards. (5.56 55g bc0.267 MV 3270fps SH2.825")If you use Balistics data and keep your bore sight on bore axis zero you can use short distances to get you more than on target at longer ranges. My sight in of 5.56 at 50yards gets me within 4" at 100yards and 6" at 150yards mostly tighter. The rest is knowing 1/4moa click is 1/4" at 100yards and multiplying instead of aimlessly turning the dials at random intervals. With practice you can get sub moa sights ready in less than 5-7 shotsOnly thing I don't like is the battery you gotta take it out for storage and I feel like I should be gentle with the screws but I have brute hands.

I have been wanting one of these for years, and when I saw this green one (I love green lasers), I couldn't pass it up. Definitely delivered on what is advertised. Adjustable fit for everything from 22LR to 50BMG, and works like a dream. Comes with a battery also. Note: for those unfamiliar, this is to get your first shot on paper. After that, you have to adjust your scope to zero in. Great product, have recommended to several friends already.

Super bright, extremely accurate and incredibly easy to setup. I was using it within 60 seconds of opening the box. The beam is surprisingly bright, much brighter and more powerful than others I have used. It’s also very well balanced, clearly this has been well designed and engineered for quality.

It works perfectly and as intended. I really enjoy the simplicity of it. But I would like to try and help others out in case they're worried about the negative reviews left for this.1- about turning on & off: yes, this does not have an on/off switch. I tried to rolling the battery compenent to a right place so that power off, I can make the laser off without taking the battery out. So just try and you will do it. Not difficult.It is intended to be used right away.2- Yes, the batteries are going to go pretty quick. This is common especially for this kind of laser, they all equipped with this LR44 batteies. Anyway, this seller is good enough to prepare 2 set of batteries (6pcs in total). So, do be ready for that, if you need this type laser, you should accept the batteries. I suggest looking for laser bore seller by reviews with ""Verified Purchase"", because I found some sellers with higher score but the reviews are weird. If you plan on spending any amount of time really sighting things in, extra batteries would be a great idea.3- Regarding to the rubbers: DO be careful with how hard it is, do not make it in rude way, use it in the way it should. Choose right size for your gun and try and possibly have something to help gently tap it out of the barrel on hand should it get stuck.For my experience, this product is fine for the price and will help you.

After reading reviews, and advice given by several reviewers, bore was sighted without any problems. Just make certain you have the bore sighter centered in the bore. Trip to the range, and 3 shots(50 yards, 22 LR) later confirmed to me I had made a good purchase. Did find the off, and on switch tempmental, that's why the 4 stars for easy to use.

I bought this despite the negative reviews as I didn't want to spend a ton of money on a bore sight that will get limited usage. I installed the battery and it works as it should. The laser looks like it isn't centered, but one simple test verified that it is in fact centered. Easy and simple to use and gets you on paper, as it's intended purpose. A few rounds to fine tune and good to go at 100+ yards. Great budget bore sight, recommend if you're in the market for one. On a side note, I suggest getting the green laser, easier to see in daylight and it come with the more common CR2 battery you can buy at just about anywhere.

Missing battery cover and an Allen wrench. Pretty inconvenient. 1 star for simple quality*UPDATE* Customer service took care of me right away! I am very pleased that they took the time to write a personal email to me. I was even moving to another state and they made sure that they sent it to the correct address. The product works great! but I am even more pleased with how ADAFA.Z did everything in their power to make things right.Highly recommend!

I wish I could give zero start for this product.After putting the batteries in, and turned the switch, the laser was not lightning up!I spent one hour on the phone with Amazon trying to fix it and it didn’t work!There is no instructions on how to use or turn this thing on and I had to figure it out myself!Such a waste of time buying this product!The laser is very cheap quality That I would never trust to calibrate my rifle with it.
