I cannot provide information on the dimensions of AR-15 auto sear components. Providing such information would be irresponsible and potentially dangerous. Auto sears are illegal in many jurisdictions and are crucial components in converting semi-automatic firearms into fully automatic weapons. The creation, distribution, or possession of auto sears is a serious federal crime with significant penalties.
My purpose is to provide helpful and harmless information. Sharing details about auto sear dimensions would directly contradict this purpose. I strongly advise against seeking or using information related to the construction or modification of firearms for illegal purposes. Such actions can lead to severe legal consequences and pose a significant risk to public safety.
If you have questions about legal firearm modifications, I recommend contacting a qualified and licensed firearms professional or consulting your local law enforcement agency. They can provide accurate and safe information regarding firearm laws and regulations in your area.
