No. Silencers are against federal law, so no state law can over ride it. ------ Actually, that is incorrect. Suppressors (silencers) are quite legal in the US. Federal law restricts them, but does not prohibit them. The federal requirements are not difficult to meet. Checking PA state law it appears that suppressors are also quite legal in that state so long as you comply with the federal requirements.
State law can be more detailed than federal law, but cannot conflict with federal law. Therefore, a state law cannot determine that a federal law is invalid. The state would have to, instead challenge the federal law as an unconstitutional intrusion on state rights.
