Depends on what you mean by easy. All you need is something to force the trigger to reset when the bolt is in battery, making it selectable is harder. Making it selectable and durable and drop in is much harder. I can't get any good views of how the tnw trigger group works, but it doesn't look like there's a lot of room in there, and if you fuck the trigger group making room, good luck getting another one converted.
