I have a better rewrite of the 2a.
All people not incarcerated, can carry arms on thier person in any manor they deem fit at all times. This is for the self defense of themselves, others and tyrants in office. No government agency can restrict the design, capcity, features, fire rate or lethality of arms. Purposing or enacting regulations that do so is a capital crime. The right of self defense is scared, any person that injures an attacker while defending thier life, great bodily injury of themselves or others, shall not be held liable for civil damages if the self defense actions are deemed justified.
Hope that clears things up.
