For RS using staggered mags watch which sides feeds first, put it, rack charging handle, pull mag out : feeding side changed = weapon feeded.
Other way (the one I use) : put mag it, rack, pull 1/2 of the way, bullet caught by extractor = feeded then release charging handle.
On my G36 GBBR : mag in, rack, mag out, pull charging handle gun facing downward (BB fall if not).
No other way to do it because if the nozzle goes back you'll double feed.
