Laser pointers? I think in the last 20 years they've been unfairly maligned as worthless mallninja shit, but they probably do have merit. Thing is, its the sort of thing you'd have to train with to be good with (if you're used to lining up sights, then ignoring the sights and focussing on the laser dot is going to feel pretty unintuitive), and because nobody takes them seriously nobody is good with them, and so the reputation persists.

For less than 20$ they’re ok for roughly aligning a sight or dot before you get out to a range.

>>64374285
they're okay if you can't see through the bore yourself, but you gotta watch if the laser is off-center

>>64374285
If you have a ~25yd. space in your house/yard, they are actually surprisingly useful and can be used to get a pretty good zero.
I forget the name of the ones I bought from (b)ass pro, but I zeroes KAC micro 25/300 sights in my backyard and they were dead on when I went to the range, didn't even need to be adjusted.

>>64374285
I personally prefer the cartridge shaped laser bore sighters. I've tried the ones in picrel and they'll get you on paper but the ones you actually chamber seem to be significantly more accurate out of the gate in my experience.

Spin it in the barrel and see if it stays at a point or scribes a circle

>>64374285
It'll get you on paper (usually), but don't expect anything more accurate than that.

>What's the consensus on these, waste of money or useful tool?
You already know the answer to your stupid question. You also know that asking it isn't going to change the answer to what you want it to be, so fuck off.

>>64374285
depends on how much it costs and how many guns & optics you have and what ammunition they use and how much each ammo costs
if it costs less than lets say 4 or 5 rounds of ammo of each of the guns & optics you own that you haven't zeroed then it's worth it

I have a sitelite brand one. it works well enough. I might consider it a waste of money if I was only using it on my own guns, but I charge people $20 to use it on theirs and made back what it cost in a week before hunting season.

>What's the consensus on these, waste of money or useful tool?
This is purely and objectively a matter of numbers anon. The point of a bore laser is to get you on paper, at 100yd even, the first shot, even if for guns where visual bore sighting is annoying/impossible. Even if you're on your own rough land so that it's challenging to spot misses. It's direct savings of some number of bullets.

So how often are you rezeroing from scratch? How many rounds does it normally take you otherwise? What's the cost per round? When you add that all up is it more than the cost of the bore laser, yes or no? That's all there is to it. If you've got a ton of guns, are shooting expensive rounds, don't have the best zeroing spot, and/or for whatever reason you tend to shift around optics a fair amount (jumping back and forth between vis and thermal say) and don't want to spend the $$$$ for multiple zero-holding Spuhr qd rings or shit like that, bore laser will easily pay for itself. Or if you've made a small business of it or side bit to your gun smith business and are zeroing other people's guns regularly and you charge for it. Again, literally paying for itself and then some, you might even want some fancier magnetic thing.

If you're one dude with a rifle or two that you take apart basically never then nah.

I like mine. A laser boresighter is just nice to have.

>>64374285
I shot one of these out of my AR. I'm not joking.

>>64374309
jfc the fact that you cant tell its a boresight shows how noguns you are

This will get you on the paper most of the time without a lead sled.

Good for practicing trigger pull and zeroing.

why are you even in this thread posting?

Idiotic. You can zero in two shots

Gets you on paper usually

No you can't see tits and I'm unwatching the tread be happy with your tidbit.

>>64379771
my point is that saying "A boresight is good for zeroing" is the most banal shit you could possibly say

>>64374285
Not really. It gets you on paper, but it isn't hard to get on paper.

>>64374285
I just buy the individual ones for specific calibres that fit in the chamber. Easy to use, helps get the scope or red dot lines up quickly before a trip to the range for final adjustments. For rifle and you dont want to spend the money and have shooting sled to hold muh gun you can just look down the barrel of a bolt gun and then adjust scope/dot before firin' muh gun.

If you can't get it held by someone just fire a shot and calculate the moa difference. I do it at 25yd, then with my scopes it's just 4 clicks per 1/4 inch off. Often like 70 clicks if I boresighted. Then go to 100yd and do it again, leave 1.5inch or so high at 100 so its flat at 200
