Good? bad? Lazy mans way, or??
LOL..

Waste of time/money. You're assuming a Walmart like product was precisely machined to be centered in the bore and for the Lazer to be centered in the bore sighter.

Also you can't see the laser on a sunny day unless it 2ft in front of you

Bore sites are only good as a very preliminary way of being sure the gun sites will get you on paper at very close distances.

They are sometimes marketed as training aides.

They aren't since they have you looking at the wrong thing.

remember: front sight, front sight. Look at the front sight, not the target.

Thanks for the replies..

I was mainly considering one for an initial tool for getting my scope and laser in the ball park..

I've always used the redneck bore sight method. Remove the bolt, set up on a sandbag, look down the bore and then look at the sights/scope and adjust as needed. I've always been on the paper first shot and most of the time only needed minimal adjustments to be dead on.

I have one for .223 Remington. Within the limt of what such a device can be expected to do, it has always worked well for me. I've seem Hollywood movies where some guy uses a laser sight to zero in a scoped rifle for a head-shot of several hundred meters and it's prefect the first time. If you're expecting that, you'll be disappointed. If you're expecting to be on an 8.5 by 11 piece of paper on the first round so that you can continue to make appropriate adjustments, that's possible.

I use it with a military-style sighting in target calibrated for 25 meters to obtain zero at 100 meters. I set it up in the longest hall in the house (45 feet) so I don't have any glare or sunlight issues, and adjust sights to line up with the laser dot. When I later get to the range, it is usually just a matter of making some small adjustments across three, four or five, five-round strings to get point of aim and point of impact to coincide.

In the end, I would say the laser saves me three or four five-round strings in getting a rifle sighted in and if you consider my reloads cost about 22 cents each, it saves $4 or $5 in ammunition costs per gun and so has pretty much paid for itself.

I agree that Ballistic147's bore-sight method is also effective, but there are guns (i.e. Ruger Mini-14, Marlin 60) you can't bore-sight.

I have no experience with the laser types. I've used the old school BSA model that works well enough to get the scope on paper but doesn't work well with high mounted scopes. For example. I have an M&P10 and a 7.62 MVP Patrol bolt rifle, both using the same scope and mount. I could bore sight the MVP but could not bore sight the M&P10.

For ARs, I've had to resort to the old method of starting at 25 yards to start the zero and move the target back every 25 yards until I get the range I need to zero the rifle. It takes more time and ammo but it works and I like shooting anyway.

I have the Leupold one with the magnet that sticks on the end of the barrel.Sounds like **** right? I have used it on my hunting shotguns,handguns and up to my 50BMG and it gets you on paper right away.Properly measure scope to barrel distance and stick it on.Adjust your scope to the target in the boresighter and done.Works great!

I use the Leupold as well; works most of the time. With a few rifles, it didn't get me on paper. With a bolt gun, you really don't need such a device. They're handiest with long guns like semi-autos, pumps and lever guns where you can't bore sight by looking down the bore.

Have used all of the above methods to get on the paper and having looked up the trajectory I zero the rifle to achieve maximum dead hold on range that will still hit a deer sized target. Most rifles will hold dead on farther out than I want to shoot at game.

It's not a waste of time/money for a boresight but it is a waste of money in the cost of ammo unless you're real lucky or get your ammo free.

I bought the "SiteLite" laser to sight in two Henry's and my AR15.I sighted all of them inside my house using a distance of 8yds for a 100yd zero.With only one minor adjustment at my range I was consistently hitting 5" steel at 100yds.If that's not good enough for hunting or self defense I don't know what would be.I don't shoot anywhere near as much as some members here so I'm not concerned with 2" groupings on paper.

The SiteLite laser comes in 3 models and each one can accommodate calibers from .22 to .50 and some shotguns.That alone should justify the money spent.

And that's my .02 cents for what it's worth.

If that's what you're looking for you won't be disappointed. Yes you have to wait until it gets to the twilight part of the day to get them to work. But depending on the scope setup you have they can be a godsend. Try setting up a 36X scope without some kind of help. It takes all day doing it the old fashioned way. Believe me I've done it. And you can't see down the bore of every rifle. That is different for rifles like an AR where you can see through the bore just fine. But I have rifles that there's no way to look through the bore. And one of them has a 36X scope on it.

Even for something as easy as a red dot sight a laser can get you going faster. The first thing I do is check the laser with the iron sights if the rifle I zeroing has them. If the bore sight is close to being right I turn on the laser and adjust my red dot until it lines up perfectly with the bore laser. You can't tell me that isn't faster than the old fashioned way.

Of course final adjustments have to be done by actual shooting. For that I want something I can see where my bullets are hitting as I shoot. I will be in the ball park already and I just walk the scope or red dot in to the POI.

I have a .223 bore sight almost identical the one you linked in the OP. It has saved me time the 2 or 3 times I've used it. It's not something that will get used a lot by most poeple. Other types of bore lasers don't work as well - not even close. This kind doesn't work nearly as well IMO.

Thanks for the replies everyone!

friend of mine has that amazon prime, so I decided heck with it, for about $12, why not give it a try.

I'll be sure and report back if anyone is interested..

I take one shot at 25 yards. If I'm not on paper, I walk downrange and shoot at 12.5 yards. Adjust your sights accordingly.

If you want to bore site the gun, pull your upper and place it on sandbags. Place a target at 50 yards look down the barrel and align it with the target. Adjust your sights so they coincide with the 50 yard target. Double check that the barrel is pointed at the target. Verify by shooting the target and adjust accordingly.

I enjoy shooting and load my own. I really could care less if it took me 20 rounds to finesse my zero. I probably would shoot another 20 rounds to verify, but the only time it took me more that 10 rounds was when I had a finicky scope.

THIS! - been doing it all my shooting life and not only ALWAYS on the paper but sometimes damn close to the center!

did the redneck bore sight method last night... and to my absolute SHOCK.. My laser was DEAD on at roughly 50 yards.. LOL

I got an old camper out in my back yard with has a 3in X 3in sticker on the back door area....
I then used a baby high chair at my patio door (LOL), some tape (and news paper for a buffer between tape and rifle to keep sticky **** off it), anyway, I propped it pretty solid..

got it set to where that sticker was dead center looking down the bore.. Then clicked on my laser, looked down the bore again and dead center..

what are the chances of that with a recent bolt on scope/laser.. wow..
Cross hairs were VERY close as well.. Might have been about one inch (if that?) off center on the 3in x 3in sticker..

the distance, sticker size and bore/hole size etc.. all worked out perfectly, if I moved the riffle, even in the slightest! the outside corner of the sticker would go out of view.. when in just the right position the sticker perfectly took up the view.. (Four corners)

I just drew this to help describe.. Thanks again for all the replies, helpful suggestions etc!

I use the redneck method to get on paper then shoot and adjust to get the zero I want. I don't consider it wasted ammo because anytime I'm shooting I'm having fun.

I've had a laser bore sighter for several years now and love it. Got it from Midway...works great.

Bright day light is not a problem at 100 yards IF one uses the adhesive backed reflective "target" that usually comes with the laser. Just don't shoot that reflective aiming target or it will be ruined...it's just for setting the scope or sights. I applied mine to a thin piece of aluminum about 8" x 12"

Don't really need it on a bolt action rifle but it is awesome with lever rifles, pumps, and AR and AK style guns.

If mine broke today I would buy another ASAP.

I've read of folks forgetting and leaving one in the muzzle then shooting...not good.

Once again you can't always look down the bore of a rifle. Not all rifles are AR's. He asked about bore sights. He didn't ask specifically about how they work with an AR. You can't do the redneck method with this one:



I grew up sighting every rifle the redneck way and with a semi-auto rifle that often meant trial and error just to get on paper. I actually learned to shoot something where you could see where your bullets were hitting even if they were missing by 3 feet. Picking the right water hole to try this is tricky but it can be done. You just want to make sure nothing is downrange no matter what. In that type of gun a bore sight is a big plus.

Agreed, but this is the S&W M&P rifle forum, so one could assume he was specifically talking about the M&P 15 rifle so thus the responses here about the redneck method.

Actually, you can... keep a dental mirror in your range bag and you can use it to look down the bore.

Regardless of rifle... I just take it down to the plinking range. Aim at a small rock, weed or debris against the dirt backstop at 60yds and see the dirt splat in relation to where I was aiming. Adjust the optic accordingly, second shot will be on paper.

If you have no reference other than a paper target it can be frustrating if the paper target can't be moved in close to start. A laser bore sight might be worthy of consideration in such conditions.

I've seen a lot of guys struggle zeroing an optic and have helped those who asked. Generally, it isn't the lack of a fancy laser but the operator not knowing what he's doing. And that's not limited to newbies. I've seen seasoned hunters struggle over the simple stuff.

When I bought my bushnell scope from Cabellas, it came with a laser boresight as part of the package. First time to use one-always used the "red neck" method in the past. That method worked great on my Contender barrels. After scope mounting on the Sport II, tried the laser and all it honestly told me was I would be somewhere on the paper at 25yds. And that's all I expected based on the design, inserted into the muzzle.

Peace was my Profession

The only time I've ever needed a bore sight was when I was zeroing a 36X scope. If you don't have a spotter it can be frustrating even when using the "redneck method". I've used that method plenty and I've also spent over an hour trying to zero a 36x scope. I used one on my AR but only because it was so easy. It is easier to do it with a bore scope. I've done it both ways. That's my opinion anyway. I don't see a lot of reason for using one with a 3-9X scope because you can generally see where you bullets hit if you did the redneck thing first. Again without a spotter it's hard to fell with a fixed power 36X scope. Until you're very close to being zeroed you won't see where the bullets hit and if you're trying to zero at 100 yards then it really gets tough. That's my reason for thinking there is some use for a bore scope. I'm not addicted to them or anything. It was cheap. And it worked better than the redneck method with a high power scope.

Oh and the dental mirror thing - that sounds tedious to me. A bore sight has to be better.

well my cheapie bore site came in today.. so this evening i will be doing some comparisons as far as the Red Neck Method VS what the bore site says etc..

Wont be till this weekend (Hopefully) that I will be able to live fire to see whats up..

That said, it did not take me long to figure out why some folks wrote bad reviews consisting of..

"It is not bright at all and flickers on and off"
"it barely comes on when I jiggle it around"
etc..

Well, it comes packaged with FOUR batteries on the side.

On the unit its self, it has a battery position diagram (+ -) on the side of it.. that shows TWO batteries, so I assumed it must have just came with Two spares, so I installed TWO batteries, and sure enough, it had to be jiggled around etc to get it to come on, flicker etc, and was in fact, dim..

So I then tried THREE batteries (LOL). it then came on perfectly, VERY bright!, NO flicker or any other kind of issue..

Apparently.. they include ONE extra battery (But it takes three).. not sure why, other then thinking someone might drop one of the tiny things and loose one.. LOL

Needless to say, I now know exactly why the bad reviews talking about the dim, flickering etc issues.. LOL

P.s.. It turns out that, even though it came with FOUR batteries, shows TWO batteries on the unit its self.. That if you break out a magnifying glass and read the instructions, they do in fact state that it uses 3 batteries..
I wonder how many people sent theirs back, or into a trash can, due to only trying it with two batts.. ouch..

Well, here is the conclusion on comparing the Red Neck view, VS what the bore site says..

Late yesterday afternoon, right as day light was starting to fade a bit, I once again checked my Laser/Dot Via the Red Neck method at a set distance..(ROUGHLY 40/50 yards)
There is NO doubt the Laser/dot was/is dead centered with the red neck method.. (My laser is GREEN)

I then installed the Bore site (Which is a red Laser)..

At the Same exact set distance and target area, there was about a 4, if not a 5in gap between the two Dots.. (possibly more, I'd have to have someone stand out there and measure, cause considering the low light i am dealing with while doing this, I am not likely to see numbers unless i make them glow in the dark.. LOL)

Hopefully very soon, I'll be able to get the time to actually go shot the thing, to confirm which is closest..

I HAVE already ran some rounds through my Sport Two, but have had no time to start dialing things in yet.. (Stock sites were dong fine for the day)..

That said.. I am leaning towards the Red Neck method Being closest, but we'll see..

All I know right now, is they don't match and are a fair amount off from each other..

I don't think either method is perfect. It's just good enough to get you on the paper. After that you walk the shots in to zero.

I am not fond of the laser bore sight, but I have started using one to save a few rounds of ammo. When I assemble a rifle and scope, I will use the laser bore to align the cross hairs with the bore at about 25 yards, so my first shots have a greater chance of being on paper. Without using a laser bore sighter, I have become very frustrated when I experienced difficulty getting on paper. The laser bore sighter is not the end all device, but it does make first trips to the range with a new rifle and scope combination more successful.

Judge control not gun control!

I hear y'all..

I don't expect either method to be an end all etc..

i'm just passing time basically until I can get time to actually go shot it some more, and curious as to the results between the two methods etc..

I gave up on them when my boresighter had me zero'd in on a wall 25 yards away at home, then when I went to the range I couldn't even hit paper. Used the redneck at the range and got her on paper first shot. Anyway, after going home and rolling the boresight on the table I noticed it was out of round. So much for cheap chinese stuff. Redneck for me and it works just fine.

I'll be really interested to hear your final results.

You don't think they're all like that do you? Mine works just fine.

Many stories like mine, so you decide.

Really? Where? I hear people saying they don't like bore sights and that they aren't helpful if you can use the redneck system but you claimed your bore sight was defective. I never saw anyone else say that.
