This is a printable stl of the badger CCL, one of the best high-impact scout rifles in Destiny.

I downloaded the STL here: http://www.destinystlgenerator.com/ then cleaned it up (A LOT. details below).
Included is the full model (complete.stl) as well as sections I've sliced to fit on my printer bed (10x10x6). You might need to scale the pieces for your print bed, or cut your own from the full model.
Clean up: barrel, stock and scope shrouds are all reproduced in 123D Design to make them thicker for printing. Side effect is they're also smoother, with a higher poly count.
The scope internals were 'thickened' in meshmixer for printability, but I used the original mesh.
The barrel, receiver and butt are all straight from bungie. would like to rework those as well at some point - to improve the model smoothness.
