Correct as always.
I forgot to mention that this is not a model that's going to end up in the game. It's simply a way for me to experiment a little, work on some techniques, try some new stuff and generally messing around (I'm actually having a laugh making the thing, always wondering what else I can whack on there to make it look even more 1337 and utterly, utterly silly). If I was going for an in-game model, I'd obviously have increased the poly count on the Aimpoint and sodded the rails, and generally paid more attention to poly count (it's about 5000 triangles right now, if memory serves) and poly distribution.
And a quick wireframe screenie for ya:
Oh, and BTW: the proportions match the reference pics I've got, so unless the pics are off, it's probably the angle of the render that screws the proportions up...
