How do gun sights work?

Mine work quite well, thank you.

they make the seals for connection points such as where the tank and the gun connect.  they prevent leaks so you dont have to keep refilling you tank every other game or so

Yes, it's called the AN/TPQ-37 Counter-Battery Artillery Radar...  It can tell you the point of origin and point of impact for an indirect round before it even impacts...  Good counter battery gun crew can return fire and take out the enemy tube before they can move...

The sling usually attaches to a but stock swivel and a swivel attached to the barrel band. Other variations have been used but thus is typical. See the examples below:\n\nhttp://www.gunsworld.com/exploded/le4mk1s.htm\nhttp://www.6th-airborne.org/index.html

Maybe your right eye is shooting the ground at its feet?

Depends on the type of monitor you have - lets assume the old tube type monitor.  In that case, the entire monitor inside the shell is a big vaccuum tube with something called an electron gun in the back.  There is phosporous compounds on the back of the glass.   The electron gun fires a particle beam at the back of the glass starting at the top left and then move to the right.  WHen it gets to the right side, it goes back to the left and down a line (I won't got into interlacing - you can look that up).  This continues until the beam gets to the lower right corner and then it shuts off and goes back to the top left and starts all over.  \n\nSo, there is a constant beam going across your screen in that typewriter fashion - it happens many times per second (depends on the monitor - this is your refresh rate).  What happens when the beam hits the glass - well, the phosphorous glows.  For each little spot on the screen, there are three colors - red, blue, and green - that can be lit up by the particle beam.  The combination of colors gives you the screen.  The more spots you have that you can light up as a rgb unit, the better the resolution on your screen.\n\nHow is this electron gun moved?  Well, it doen't really move.  The  direction of the beam is altred by electromagnets aroudn the yolk of the glass tube (the yoke is the smaller part near the back).  power is applied to the magnets to control or bend the electorn beam.  These control magnets are controlled by the inputs from the video card from the main pc.\n\nSo, if you opened up an old tube TV or tube based (analog) monitor, you will find a big vaccuum tube wiht wires running around it and a circuit board or two.\n\nLCD and plasma work a bit differently.

yeah right...i suppose green pigs swim upside down in you're world too eh? my apologies...a friend told me today that a dummy round can be inserted into the breach which has a laser pointer mounted in it to allow fine scope adjustment...i eat my words...

try looking at http://www.gunpartscorp.com/ they have a large assortment of gun parts.  If you have no luck there then you may want to go to http://www.trijicon-inc.com/home.cfm they make very good nite sights.

I will only add to what mousehound says, since his answer is so good.\n\nAs to if silencers work on all guns - no. \n\nTwo reasons:\n\n1) Gas operated automatics tend to channel some of the expanding gases to operate the rechambering of another round, the sound from these gases isn't suppressed, because it doesn't go thru the suppressor.\n\n2) Some, BUT NOT ALL, guns fire rounds which are supersonic. Virtually all handguns fire rounds that are subsonic. Supersonic rounds will create a shock-wave after leaving the barrel. The suppressor only suppresses the sound made by the expanding gases of the exploding powder.\n\n\nThe mechanisms for suppressing sound is, like a previous answer said, act like a muffler - it forces differing portions of the expanding gases through differing length baffles, both slowing and causing the differing path's peak shock wave to escape at a slightly different time, thus widening the sharp crack (shock wave crest) made by the (exploding) expanding gases. \n\nThis is a form of harmonic sound suppression.

With all due respect to bobo, guns fire just fine underwater - just make sure the entire barrel is flooded with water and that your bullets aren't hollowpoint so they don't expand in the barrel.\n\nDoing that will really screw up your gun, but the cartridge will fire unless it has water inside. Metallic cartridges make their own oxygen as they combust; they'd work just fine in outer space minus the loud noise.

A Laser jammer uses a infra-red LEDs or laser diodes to distort the signal of the police lidar gun.\n\nA great place to find out about laser jamming products results would be to go to the websites I linked below: http://guysoflidar.com/index.html\nhttp://guysoflidar.com/radar-detector-laser-jammer-shootout-2005/laser-jammer-tests.html\nhttp://guysoflidar.com/laser-jammer-test-july-2005/index.html\nRocky Mountain Radar products do NOT work!\nhttp://www.radarjammer.com/\n\nYou can see some videos of Laser jammers and Laser stealth coating here:\nhttp://www.laserveil.com/cool%5Fvideos/

first make sure the scope mounts are matched as a set\nthen check to see that they are mounted properly to the base\nalso check that the scope base is properly mounted and is the correct type for your gun\nif all is good cut up an aluminum can and try shimming the scope inside the rings\ncans typically are .005 thick\nyou may use up to 2 pieces\ncut the aluminum to fit exactly to the size of the rings and shim the bottom half of the ring where the scope sits in it\nwhile you have the scope off check carefully to assure that the scope tube is not bent\nthis happens when people dont set the scope in the rings and over tighten the screws

on the gun theres the bolt you have to pull it back before you screw the tank in.

There is another reason.\n\nOnce this convention was set up, video game makers brought out optical sensing guns / pointers that would make use of this scanning feature to determine where the gun was pointed when the trigger is fired.\n\nBasically, these devices blank out the screen when the trigger is depressed, and start a counter. Since the screen has to be refressed from L to R and then the next row and so on, it can determine the time required for the screen to blank to the position it is aimed at. The controller then determines the position by interpolating the time.\n\nSince no one wants to break these devices by choosing any other convention, it stuck.\n\nThere may be reasons why it was chosen in the first place. The ray is actually moved by magnetic fields, and usually a ramp is used to generate this field. Therefore once it has moved to the right, the ramp is reset and the motion resumes from the left.

You can use these sights.

My son has a cheap red laser pointer (well under $10)\nwhich has a few "lenses" that he can screw on the\nfront to make different patterns.\n\nI don't know if these things are strictly "lenses",\nbut they distort/focus/shape the laser dot to\nlook like a star, a line, or a couple of other\npatterns.\n\nIn any case, one causes the laser pointer to produce a\n"line" rather than a "dot", and that seems like it would\nsatisfy some of your needs.  The width isn't readily\nadjustable, but the the length would be (by covering\npart of the "line" just past the light source).

it is almost impossible for the novice.\n\nYou can drift the sight over a bit using a pin punch and a small jeweller's hammer\n\nOr you can invest in one of the sight adjustment vices that push the sight over using a small screw device\n\nOr you can try to find a competent gun smith who will guarantee his work.\n\nGood luck, the rear sight should drift to compensate for a bad frontsite
