RE dvdcrr: Arsenal did not fix it, that's why I'm upset and writing this post. Now, I'm considering what I should do. I'm going to give Arsenal a chance to at least offer me a fix, and maybe I'll send it to a custom shop or replace the top cover.
On the topcover, it is perfectly flush with surface of the safety when it hits the topcover. The safety does and did drag across the surface of the receiver when it is moved. It's more snug after Arsenal's "fix," however.
