I'm clueless on what to replace an A2 with. I picked up a simple thread protector, but I'm thinking something like this would be much more beneficial. Surefire, Warden Blast Regulator . I've felt what it feels like to be shooting next to someone that has a side exits device. It's not pleasant. With all the regs and restrictions, I'm unsure if this would be legal.
Is this good to go in CA?
