This is a rifle I originally designed using LDD 1.6. I did build a real version of the model and it has great balance, very sturdy. I decided to do this updated version with 4.3 to add some more details and to have a file in case I disassemble my real one. I call this rifle "The Doctor" because when I hold it, I feel like it's designed for surgical strikes. It measures just over 21" long. It comes with a removable magazine, and a silencer.
