I thought the issue was the trigger hook being too tall, but it looks like the factory trigger hook is *almost* as tall.
So, I guess the issue is the trigger hook being too wide. (either/or, really)
The factory trigger hook curves outward at the top, allowing the bolt carrier to pass by on the side, while the AKT trigger hook just goes straight up and gets in the way.
(The Tapco G2 trigger hook just goes straight up too, but it's much shorter, allowing the bolt carrier to pass by over top.)
Now, for the million dollar question. To make the AKT work in my mini Draco, should I try to bend the top of the trigger hook outward, file it down on top, or file down the inside edge?
