I have never used a bore sighter before, just wondering if they are a good tool to have around?

Will they put your rifle pretty close at 100 yards, without having to shoot it?  

Also, can anyone recommend a good one?  I've seen the little 223 size ones, that you can fit in a sleeve of another caliber to fit your rifle.

Thanks

i don't really have any use for them. with iron sights you should be close enough on paper to see where the shot went and adjust accordingly. if needed one could get closer to dial in a scope at 25yds and then move back from there. i can't really justify the price of a bore sighter.

Bore sighters are for folks with more money than common sense IMHO.

Bench a bolt rifle, remove the bolt and while sighting "through" the bore align the bore with the center of a 100 yard target.

Holding the rifle tight w/ the bore aligned as noted - simply crank the scope crosshairs until they have the same POA.

You'll be on target w/ only minimal adjustments required.

Do the same with a semi-auto like the AR15.

Seperate the upper from the lower and w/ the BCG removed from the upper; bench the upper.

Just like the bolt rifle, sight thru the bore, hold the upper tight and adjust the scope to the same POA you are seeing thru the bore. With minimal rounds fine tune the zero.

How hard is this? it ain't.

ps - yes there are rifles for which this method will not work "lever action rifles" for one, M14s and Garands for others - but then I have never found a need to waste my money on a bore sighter for them either as I simply start at 25 yards where there's far less chance of missing the backstop/target. A few rounds gets ya squared away up close making the fine tuning at whatever range afterward fairly simple

I just bought a bushnell laser sighter and used it to sight in the new night sights and the laser pointer.  It is actually very helpful.  I wish I had it when I sighted in my STG556.  I fired 50 rounds at 100yds without a  spotting scope.  Not one printed on the target.  It was rainy so I could not see the impact on the ground to even know if I was close.  I like mine and it's good for all common calibers.  What was nice was to be able to pinpoint my laser aimer on my USP40 at CQC ranges in the house without shooting.

An optical collimator or laser boresight is simply a tool.
If you do not see the need for said tool, than chances are, you don't need it.

I find the one I have has been well worth the money, simply in customer satisfaction.
I spend less time fiddling at the range, potentially burning up frighteningly expensive ammo.

I have also found them useful for when I have to fabricate front sights for old military rifles to adjust the battlesight zero. The customer still has the origional sight, and now is putting shots on paper without resorting to gross hold under at 100 yards or inward.

Save your money and buy more ammo with what you were going to spend------and learn how to bore sight old school.

I have a cheapie one I picked up for $30 or so. It just shoves in the muzzle and goes.

I've used it for pistols, rifles, etc. It works the vast majority of time without having to hold the rifle steady, etc.

I've also used the "sight through the bore" method and it also works depending on what you have to sight at.

Ideally the best either of these methods do is get you on paper within 6 inches or so at 50 yards.

Is it necessary...no, but it does make it convenient.
