YT has said no full auto so here's Brandon Herrera giving YT the middle finger, sort of*, with a Ma Duce

*It's semi
If you know this, then I'm sorry, but in case you missed the tounge in cheek:
That's a Full Auto M2. An M2 has a mode selector that lets you run it in single shot mode and locks the bolt to the rear, forcing you to hit the bolt release (that button in the middle of the butterfly trigger) to send the bolt home and chamber the next round. In the shots where Brandon is holding the trigger and getting one shot, it's in single shot mode.
In the wide shot's where he's "pulling the trigger really fast" he's put it back in auto and it's shooting automatically.
FWIW, if your interested the "selector" is just a metal clip that holds the bolt release button down. An M2 fires from a closed bolt, unlike most other beltfed's in US Inventory.
