Make sure you know the laws about airsoft in Surprise. If I remember correctly, i don't think you can discharge an airsoft replica anywhere within the city limits legally under any circumstance.
Sec. 34-73. Restrictions on discharge, concealment and handling.
It is unlawful for any person within the limits of the city to fire or discharge:
(a) Any firearm, BB gun, air gun, pellet gun, dart gun, slingshot, gas-operated gun, cross bow, blow gun, or other similar gun or instrument; or
(b) Any arrow from a bow unless:
(1) The discharge occurs on private property, with the consent of the owner, from a location no less than 125 feet from any property line, by an individual or under the supervision of an individual who is 18 years of age or older; or
(2) The discharge is done by a government agent in furtherance of his or her official duties; or
(3) The discharge is done pursuant to Title 13, Chapter 4, Arizona Revised Statute
; or
(4) The discharge occurs on non-residential property as part of a properly supervised range. Properly supervised range means any non-residential location operated by or immediately supervised by a governmental agency, public or private school, or an adult who is a member of a company, group, or affiliated with a recognized archery shooting organization.
Sec. 38-27. Fireworks; fires; glass; weapons; violations.
