For my first build, I may end up screwing my rails to the receiver rather than welding. I don't have a welder and may just see how screws look. I think I'm going to go ahead and order some and see how they look. I wanted to get some opinions on what screws would do the trick for the rails (proper strength) and what type of screw looks the best if you have to use them in a build. I've been looking at some on microfasteners.com.
