Adjusting My Red Dot Sight.

I've been having problems adjusting my front sight...

When I'm shooting 3-4 meters away from my target, my shots are always under the red dot.

But when I move back another 1-2 meters, my shots are always above the red dot.

My hop up is completely off and I use an ICS 41 A1 (M4).

Any help?

Well you need to use your hop up to make your BB have a level flight path. Why try adjusting your red dot sight to the BB's trajectory with no hop up?

Try to zero your sight at around 50-60 feet.

You're experiencing what's called "Parallax."

http://en.wikipedia.org/wiki/Parallax


Basically, you're comparing two different trajectories... at some point, they will meet in the middle, but when you're trying to zero at such a close range, if you try to hit a target out at 150 feet, you'll be so far off your RDS picture, that you won't even know where the BB is. It'll be right out of your sight picture.

There's no point in zeroing at 3-4 metres, because you'll almost never shoot a target that close, and it will give a very extreme parallax difference between your sight trajectory and your actual shot trajectory. The *minimum* distance you should be zeroing in at is 30 feet, ideally 50 or even 70 feet.

Hop doesn't effect bb's until about 30feet out... which is about 10 meters.

My suggestion.

1. Get a straight area to the target of about 75feet (20M)
2. Adjust your hop so that the BB will curve upwards a bit before hitting the target, don't bother with your iron sights yet.
3. When you get the bb flying straight-ish with the hop. Adjust your irons until your bb strikes where you aim with the irons.
4. Now adjust your red dot so that when looking through the rear sight, you can see the red dot in line with the front sight.
5. Now when you look over your rear sight, your red dot will be above your front sight, but should still be on target with where you are aiming.

And after you've done what the guys up top here say, zero your iron sights also.

The sad part is, I already saw off the front sight because the scope was too low compare to the front and rare sight's line of sight.

Is there something else I could do?

You didn't have to saw off the front sight... A rail riser or carry handle mount would have done the trick. In any case, you're using a range that's too short to zero. You can still use ShelledPants' instructions, just omit the lining it up with iron sights part. Once the hop is set properly, use paper targets to see where the point of impact of your BBs are and adjust the red dot to meet that.

Without the ironsights... you'd need to strap the gun to a table to match the red dot with the bb impact.

This reminds me of that picture where the guy sawed off some tabs on his GFX card so it'd fit in the slot :P

Alright, so I tested my gun out today and it seems there's another problem appear.

When I fire my bb while looking through my red dot scope, the bb look like it's going in an arc motion. But when I push the hop up down a bit, it's almost look like it's going in an long "s" shape....

Like, from the looks of it thhrough my scope, it goes up a bit, then falls down a bit, and then the hop up comes into play...

Maybe it's the way I'm holding the gun that's giving me the error, any help is appreciated.
