I'm building a .223 upper and I can't decide on what to put on the threaded barrel. I'm hoping the hearing protection bill gains traction so I can thing about a can but in the mean time it will need something. I was leaning towards the Miculek compensator but decent pricing and supply are hard to find not impossible. I was thinking of getting a Spike's tactical Sd-1 or a car-1 as a place holder giving it a sbr look until I find what I want, or maybe just a thread protector. Any opinions or recomendations are appreciated.
