This idea came into my head: has this ever been done? if so links pls. if youre not familiar with this trigger it technically is semi-auto, here's a vid: fastforward to 2:16 Would this be allowed in semi-auto only games? i can see some restrictions. My idea involves (m4 platform/v2 gearbox) ditching the semi-auto latch completely, therefore leaving any trigger contact shooting full auto. Now heres where a mosfet with burst-instead-of-full-auto comes in. slow down the burst rate to a single shot. you'd be limited to Safe and binary selection only. hardest part is a custom trigger which brushes/makes contact on the pull stoke and brushes on the trigger release. you'd also need quite a responsive setup, especially if you can feather that trigger quickly. hope this info ignites someone to try this out before i do!
