at over maximum aeg range you can see it arching down, hop up adjusted properly, and elevation set up to keep the bb in view as much as possible for its entire flight (zeroed in somewhere around 80-90 feet). however, since most scopes are not made specifically for the low velocities of airsoft, if you use the scope on the higher settings, or just any bigger than 4X and aim around lets say around 500 feet away... im pretty sure you would notice the drop. btw, anyone got a cheap 2x scope up for sale?
yeah, im aware of the idiot's mark that you get when the recoil pushes the scope into your eye, i didnt mean it literally that close, even for airsoft (got shot in the arm while aiming once and flinched the scope into my goggles hard enough to scratch them)
as for the part of fov... we got a poll on the first page... not everybody uses both eyes open when looking through a scope, so i guess it would depend more on your style.
i got both rds and regular scopes for mine, and i tried different mounting options. to me it seems that the rds work better mounted further down the gun. its just easier to use both eyes that way, while i found that with my scopes its better if theyre closer so you dont have to look through a straw or get the scope shadow.
but back on topic - what i really think nic was refering to was some of the pics that show the m14 with the forward mounted aimpoint vs a traditional scope.
while i really, really hate the look of an aimpoint on a m14, ill admit it looks like an effective setup. you dont really need the magnification of a scope in airsoft since you dont have the range for it. so a forward mounted rds would be effective especially for fast target aquisition, but... did i mention that i really, really hate how it looks?
on the other hand, a scope would look cool, but you might be disapointed with the results.
