I do not believe the brady bill has a sunset clause, the only clause was the instant back ground check (NICS) that got rid of the 5 day waiting period on the national level (many states have their own waiting periods) and that clause has been met. The 10 round mag limit was I believe the assualt weapons ban, which I believe has a sunset clause that goes into effect the end of this year or sometime next year (provided its not renewed by congress).
