Oklahoma Gun Laws & Firearms Safety Practice Exam

Oklahoma uses the federal National Instant Criminal Background Check System (NICS) for firearm purchases from licensed dealers. This system is used to quickly check the criminal and mental health records of potential gun buyers. Option A is incorrect because the question specifically mentions that the system used is for firearm purchases from licensed dealers, not just any background check in the state. Option C is incorrect because it suggests that Oklahoma has its own separate background check system in addition to using NICS, which is not the case. Option D is incorrect because all licensed firearm dealers in the US are required to conduct a NICS check on potential buyers, unless the state has its own approved alternative system.
