hey guys, thanks for the feedback
the spring looking thing is actually two high voltage wires that carry power to the laser scope and for the electronics of the gun/ aiming. the two arms are for recoil and also for manuovering the thing up and down since it would weigh pretty heavy. could also be stabliziers (bad spelling ) when its mounted on vehicles.
the shading isnt very good, its just the edgesplit modifier, in game it will be completley smooth, but when rendering it looks crap with all smooth. will look good with textures though
would be cool to have exploding rounds on it, would be cool to tag some one with exploding bullets so they think they have got away and then BOOM!
could also have tracer bullets that flare up to pin point enemies for your troops, tracker bullets so you can track enemeis on the ground, could work for vehicles too.
