jusus no it doesn't.. Dos Not require a cough and tickle!!! I just got word its every 5 years to be able to buy a semi auto, you have to be certified as safe. Take a saftey class with a professional that is certified by the state.. so even leo's I believe have to be certified. Im learning but the laws are very confusing and for lgs its contradicting! its gonna put them out of the guideline and out of business.
