easy..you cant.
The front sight is mounted on a "dove tail", you just tap it out of the notch in the ramp with a hammer and a punch or drift pin. The ramp is welded on, you cant take it off.
IF IN FACTORY CONFIGURATION, The front sight is fixed and not adjustable. The rear sight is drift adjustable for windage changes - you need to loosen the set screw that holds the rear sight in place. From what I've found, it may take some doing to get that set screw loosened.
press down on the front sight and turn the hopper downwards
You are looking for the "sight picture". that is formed when you align the rear sight with the front sight and the target. Here is how to find it. At the very end of the barrel on top is the front sight. About 2/3 of the way back and still on top is the rear sight. If you hold the rifle stock to your shoulder and support the front of the weapon with one hand you can look down the barrel. You will notice the rear sight looks something like a V and the front sight will look like a dot. If you move the rifle so that the dot appears to be in the middle of that V you have accomplished your initial "sight picture". Now keeping the dot in the center of the V align that with the target you wish to hit. This is your complete sight picture. It will take practice to figure out if the wind is affecting you and distance to the target and a lot of other things but that is the correct way to sight the rifle in and should get you started. Good luck.
You have to remove the drive shaft and take to to a machine shop. It has to be pressed off Rob
Most air rifles have the front sight pressed on. Others have a small Allen screw that holds them in place. If it's pressed on then you can take a small block of wood and using a hammer you can budge it off. If it's an Allen screw then back off the screw and slide off the sight.
take the laundry to your mum.
The front sight is secured by the top screw above the barrel, while the rear sight is secured in place by a screw just behind it.Check your manual, it may provide tips or have a troubleshooting guide.
You don't take it to a professor you take it to Celio in the one island Pokemon center he's the guy standing in front of the very large machine.
if your starting at level 1range and level 3-15 combat it will take around 4 months combat level 16-30 it will take 2 and a half months combat level 31-60 it will take around 1 and a half months combat level 60+ will take 1 month or less
it should be in your manual (pretty recent machine), could have a sight window and or writte as a part of the casting and if all else fails, call the dealer
