Making a .22 supressor without a license is a federal crime.
You use the Supressor. It is an attachment for your gun
A shoulder stock permits a more steady aim, and generally improves accuracy.
This is a device which dampens the flame which comes out the muzzle of the gun when it is fired. The supressor reduces the dazzling light that would temporarily blind the shooter or reveal his position.
You can't. In order to make the game seem more lifelike Activision made it so your hand moves from just like in real life. It is nearly impossible to hold a gun completely still when it is not on a base of some sort.
Take a steady aim.
Sometimes it will.
A BAU agent is allowed to carry a gun as long as they have passed their test to be eligible to carry and shoot a gun. To be able to carry a gun you must know how to shoot and hold the gun steady. More correctly, you have to be able to pass the FBI shooting qualification test, and that applies to all agents, not just BAU.
I'm not sure which type of supressor you mean. There are external supressors which screw on to the end of the barrell like a real gun and there are internal supressors. External supressors are purely cosmetic and will not change the way your gun fires. Internal supressors will decrease the noise your gun makes as it fires. They are not too common and need to fitted by a profesional airsmith. My best advice is if you want one fitting to go down to your local shop and ask about them. Hope i helped . :) You can get a mock suppressor that just makes your gun look cool (and it actually decreases the sound a little bit), one that makes the sound louder, or more recently they started making mock suppressors that when used with certain bb's caused them to light up making a "tracer" effect.
The armband is used to steady the gun while they shoot. There's a small attachment to the sling of the gun that helps hold the gun securely to the shoulder.
hold the gun steady, twist the tank counterclockwise.
If your aircraft is on the ground, a steady red light from the control tower light gun means STOP. If you are airborne, a steady red light means to give way to other aircraft, and continue circling.
