				"Toggle"	"1" // Toggles bodygroup if it gets input.
				"UseButton"   "1" // Uses the "use" button to turn on.
				"LowerWeapon"   "1" // Lowers and hides the weapon before toggling the bodygroup.
				"UseIronsight"    "1" // Turns on if ironsight is on.
				"DeactivateinReload"    "1" // Turns off in reload.
				"ChangeIronsight"	"1" // Changes Ironsight when on

// Those are the main options I could think of if you're just adding a sight or maybe a laser sight.
// Other options could involve enabling secondary fire or changing damage value, sounds, and other things. I thought that would be too complicated so I didn't include it in the above. Those are the options I would mainly want. Here  is some other ones that would be nice to have.
"EnableSecondaryFire"	"1" // Enables Secondary fire while this bodygroup is on.
"EnableIronsight"	"1" // Ironsights can only be used if this bodygroup is on.
"ChangeDamage"		"40" // Changes damage to this value.
"ChangeSoundData"	"1" // Changes sound files if bodygroup is on. You put sounddata after this like normal.

// Here is a real example of a bodygroup for an ACOG.

						"right" "2.85"
						"up"    "0.2"
						"AdjustAccuracy" "0.4"

// Here is an another example for a laser sight. Very simple. This will be included within the bodygroup block.

// So basically that's all you need to do. If this is very hard to implement I understand.
// Thanks for reading.
