So i went back and did some tweaking to cover up some white space. The sides have some armor plating to help defend the internal parts from taking a stray bullet and breaking down.

I also scale up a muzzle break i hadn't used but had laying around and put it to some use. I think it looks a bit better with the shorter muzzle break.

Not much to really say other than I added a fair bit of detail.
