Just got a new g&g gr16 hopup. When looking down the feed tube you can see a gap where the control arm would sit. Light shines through it.
The issue I have is when I slap in a mag the BBs will feed into the chamber with the top BB sitting in this gap. This seems to prevent the nozzle from correctly impacting the BB, allowing it to pass through the bucking lip.
If I manually drop a BB into the chamber it would just sit correctly up against the bucking lips and will fire just fine.
Is this gap supposed to serve any purpose?
