I got myself an ak 74 barrel, w/ bayonet lug and threaded barrel. I live in a ban state, so both those features have to come off, or at least the lug does and I need to permanently attach a muzzle break. I don't really know much about 24mm breaks, so I don't know if I want to make one a permanent part of my rifle. I like the flash hider avaliable in 24mm, but It's another no-no in my state. that being said, I have a replacement front sight block w/o threads or a lug. Is it possible to swap these parts out with hand tools or will I need a press?
