Thank you for the very quick reply!
1. I brought it up bc my buddy's VFC does not sit so, but maybe that is reducing his seal a bit.
2. It's basically all or none the way it works. Even with the smallest of adjustments, as well as side spin (shot within a gym). The flat hop I made for my G36 functions better. Not a huge deal for now.
3. Problem solved! The Springer terminals at the back of the gear box were jammed with shredded heat shrink. This prevented them from springing out far enough to consistently touch the stock contacts. Cleaned up and works great!
