IMHO, unless the target you're hunting is hunting you, too, a flash hider isn't all that necessary. You might go threaded to add a compensator or suppressor later on, though. If I ever settle down in a NFA-friendly state, I'll have to thread or replace a few barrels to mount suppressors. If you think you'll go down that road, save the extra step and buy threaded now with a screw-on thread protector.
