Off the top of my head

round off the purple areas and get rid of the embedding where the red is. Rotate the bolt handle as seen here

pull the handle out a bit, make the holes in the side shorter, get rid of the grooves on the front grip, add safety and whatever that thing by the bolt is, you're also gonna wanna add the front pop up sights and still gotta make it skinnier and see if you can do something to the stock to make it less boring
Has anyone ever tried normal maps in Blockland?
this version of torque does not support normal maps.
