Laser questions

Yes, I know that adding a laser to your rifle makes you a mall ninja. However, I have a pretty good reason for wanting to do it (I'll explain at the end). Yes, I'm going to do it. No, I'm not going to change my mind. Let's not turn this into a discussion of the relative worth of tacticrap.

Here are my questions:

Fed.gov limits the outputs of lasers (for our own safety), and many of the makers seem to say or imply that their laser is the brightest allowable under the law. From this I gather that the light output from most of the lasers is substantially similar. Is this correct?

If so, is it correct to believe that most of the price difference is due to the basic quality/durability of the device and the battery life, and not so much due to the quality/visibility/brightness of the dot? I am aware that green seems brighter to the human eye and the lasers that produce green beams are more expensive to manufacture, so that is one price difference.

Finally, if you were to select a laser for a rifle, which laser would you go with, and why? Assume the purpose would be night-time CQB and engagement out to 100 yds.

Thanks,

Mike

PS The reason is this. I have a KTR which has a dust cover rail/iron sight which holds its zero very well. However, the return to zero capabilities are less than ideal, which is problematic if you actually believe in cleaning your rifle. It looks like the RTZ error is well eithin the "wobble area" of me using iron sights in practical combat shooting, so this leads me to try and not turn this rifle into something it isn't (by trying to figure out a way to put a red dot or low power scope on it) and embrace what it is (a simple little iron-sight fighting carbine with rails on the forearm). One way to do this is to keep the irons and add a laser and light to the forward rail system, and turn it into a nice "night fighter".

i've wondered the same thing, coronach, but I assumed that even though input power was limited, there was still a wide degree of variance in quality of optics and electronics.

i'd go with an IR laser :)

I have tried several lasers over the years and this AimShot laser is by far the best I have seen. On a cloudy day I can see the laser at 100 yards fairly well even with my old eyes.

i'd go with an IR laserKnow where I can get one? I'd love to have one, along with a AN/PVS-14. :D That would make this thing a real "night fighter"!

Also, anyone know where I can find a winning lotto ticket? :rolleyes:

Mike :D

I think it has more to do with the wavelenghth more than the output power level, since as you mention, they are all at the same or darn near the same power output due to the govt limit. At the same power, the wavelegth will determine how far the dot is visible, especially in other than low light, and I think it also affects how much the size of the dot increases with distance too.Not 100% sure on all this, but I seem to recall hearing/reading all this at some point when I was looking into lasers too. Of course, quality/durability will obviousy affect price a fair bit too like you said, as it does wth everything else, so a laser will be no different.If I'm wrong on the wavelenght thing, some physics geek :neener: will be along to straighten it out I'm sure.If I'm on the right track, they should be able to tell you whether its shorter on longer wavelengh you want for what, as I dont recall, and physics was a LONG time ago.:o

coronach, i know where the guy is i sold my IR laser to :)
i'm sure he'd part with it if you offered enough. I think he gave me $550 for it.

Hmm! Most places sell them to LE or .mil only. I'm LE, but my chain of command won't allow letterhead for personal purchases (and well they shouldn't), so it would have to be an outlet that sold just based upon credentials (which I do have, naturally).

Where'd you get it?
