    Ok here is my problem. How do they work??? If you move your eye just a bit it move the dot. How do you know when your on target? Is a front sight required?

    Wherever the dot is, is where the round goes (assuming you have sighted it in correctly). Doesn't matter if the dot moves.

    That is the beauty of the red dot sights.

    I think KAG is referring to parallax. I also would like to know the answer to this. I understand how it works in rifle scopes but red dots seem to have a much bigger problem with it (maybe i've only seen the cheap ones).

    We'll just have to wait for one od the smart fellers to come along. :D

    While I put an ACOG on my AR, I can tell you that the vast majority of our soldiers in combat have Eotech's on their rifle (my son does). From talking to my soldier buddies, the cheapies are basically a waste of money and won't hold zero or stand up to any hard use.

    This is why I love where I work, I get first hand info from the folks that actually use their weapons in real combat environments. If I had not needed magnification (old eyes) an Eotech would have been my choice.

    I know a couple of soldier types testing out this one and initial reports say it's a keeper...

    I looked at one a friend bought for $30 to put on his 10/22, and while I was in his house I was playing with it. If it was a the same position and my eye moved around, so did the dot. Now I am not dot scientist but I dont think the bullet will some how follow the dot around.

    My explanation:
    Brain cell #4555566 must have stopped talking to #4555567.

    They work like a HUD (Heads Up Display), basically. There is no magnification, so no paralax. When a fighter pilot moves his head, it does not affect his weapon sight (HUD), because the sight moves to compensate.

    I have used Aimpoints for years (first tried in the late 80's), and can tell you that as your head/eye moves and the dot moves, so does the bullet impact.

    This is an oversimplification, but I hope it makes sense.

    I might have to spend the $30 just to find out. I understand what your saying it just does not compute. :confused:

    That was my response originally. Ha.

    One thing to remember with the $30 units is that they do not have the durability, repeatability and longevity of the Aimpoints. I mounted a cheapie on one of my .22's a few years ago and was pissed when it would not turn on early one morning in the dez (20 degrees). Once the day warmed up it was fine. I blamed the batteries, but found out later it is the electronics.

    The Aimpoints are tested down to insane temps, and back up to insane temps (like -165deg f to +200deg f). It is the same reason the AP battery life is measured in years, when the cheapies are in hours. I have an Aimpoint for my backup hunting rifle (along with a magnified scope) and it works just fine at well below 0deg f, and it keeps it's zero after days of rough riding and hundreds of miles on a hard rack on my ATV.

    But get a cheapie and play with it. You will enjoy the versatility and simplicity of a red dot once you get used to them, most likely.

    there is no parrallax, as ther is no magnification involved with this type of red dot.

    when sighting in, keep the target in the center of the glass and adjust the red dot until you hit what you are aiming at.

    the red dots are nice for fast target aquisition, both eyes open QCB style shooting and short range target as well. the variable brightness dot offers you the oppurtunity to not get distracted by the glare of the dot, and is nice for night varminting.

    i have a similar one, (this style is basically tasco, bsa, and a half a dozen other names printed on the side) on a .357 revolver. held true for years. then i put it on a shotgun 835 3.5" dead coyote loads, still stays true.

    i'm about to buy another (tasco offers them with lifetime warranties) to put back on the .357

    I have the same red dot for my AR. I sighted it in at about 25 yards, and it works quite well. I got it using my credit card reward points! :D

    Here is a good experiment for you. I you or a friend have a rifle with a red-dot type optic on it, put it in a vise, adjust the vise so that the dot is centered on a terrain feature that you'll remember. Now, move your head up and down, and side to side behind the optic. Watch what the dot "Does."

    Was wondering if you had gotten a chance to try this out? Sorry to resurrect an old thread, and you may have already posted the response, but I'm pretty lazy.

    Thanks :)

    I have this on my AR.

    Trijicon, Inc. : Brilliant Aiming Solutions

    I have an Aimpoint on a Ruger 22/45 that stays true all the time. As far as the red dot goes, I can't explain it, but I know for a fact that it doesn't matter where the dot is in relation to the center of the display, the bullet will hit where the dot is (if it's sighted in correctly). This is what makes the red dot system so great, you don't have to worry about sight picture like you do with open sights. Quicker on target, easier also on a moving target. My 2 cts.

    As long as it's zeroed, it'll still hit where the dot is.

    The annoying part is zeroing it in. I always have more trouble zeroing in red dots than I do iron sights 'cause I fidget to much and don't always maintain the same cheek weld.

    I have one with 3 dots. The idea is to sight in the top dot at say 50 yards and the bottom dot will be set on some longer distance. What does the instructions say?

    If multi-dot sights blend or blur together then the power is set too high. The power should be set where you can just see the dot depending on light conditions.
