would be cool to be able to position any sight (reflex and redot to higher powered sights like acog and sniper scopes) on the sight rail of any gun that has a sight rail.

ive noticed that with alot of the assult rifles, the acog sight (for example) is positioned differently on the sight rail, such that on one assult rifle, the scope is close to the rear iron sight (which means the acog scope is alot closer to the face, the scope takes up much of the screen blocking peripheral vision, BUT allowing for greater zoom).

while another assult rifle's acog is positioned farther away from the rear iron sight having the opposite effect: the scope takes less space on the screen, allows for peripheral vision, but the zoom is less).

The same thing applies to other weapon classes (SMGs, LMGs, Sniper rifles, etc.).

How feasable is an adjustable sight rail in insurgency? is it do-able?
