Hello, I'm new to the forums and new to the gun world. I have a crazy idea but I'll need your expertise! I plan on bisecting a gun in half lengthwise so I could place it into a display case as art. And I was wondering: 1. What type of rifle is the most popular in the US gun world? Or what [affordable] gun would you like hung on your wall? (I was thinking the M4 because I feel its the iconic American gun. Although I could be completely wrong) 2. What should I look for to purchase this gun? Thanks in advance for all your help.
