CMA Rules

CMA Rules

Are you ready for some adventure?


Have you ever wanted to be in the military, but wasn’t able to get in?  Do you play first person shooter games on your gaming system?  Have you ever been in the military?  Are you in Law Enforcement?   Do you love adrenaline?  Do you love to have fun while getting a work-out? Then airsoft is for you!


Welcome to Center Mass Airsoft, one of the largest teams in the Kansas City area and an avid Airsoft community partner.  But don’t let our geographical location limit your perception of us, as CMA attends several large regional Ops, and since our conception have donated nearly $2,500 to Homes For Our Troops. All of us are committed to promoting Airsoft and its benefits.  Browse our webpages and community and see if CMA is a good fit for you.

Thank you for visiting our website! Be sure to check us out on Facebook! We look forward to hearing from you!



Release of Liability Waiver must be signed by all participants and observers who intend to enter the CMA field.  Please print the waiver as duplex (2-sided).  Blank waivers are also available on-site.

CMA Age Restrictions

  • 18+ –  Players may sign team waivers without a parent or guardian.  
  • 15-17 – A parent or legal guardian must be present, with a valid ID or legal court documents (proving guardianship) to sign the waiver, after which, they can leave.  Generally, this is done once per calendar year.  
  • 12-14 –  A parent or legal guardian is required to sign the waiver and be present at the game, but are not obligated to play.  Any parent/guardian who wishes to play with their children is more than welcome to as long as the child can handle themselves on the field.  If it is determined the child is unsuited to play Airsoft, it is asked they wait until the child matures before returning.

For non CMA games you will need to see the hosting team’s rules.

CMA BB Weight Restrictions

Heaviest – 0.32g
Lightest – 0.20g

All guns must be chronoed with .20g BBs, regardless of what weight is desired for gameplay.  BBs lighter that .20g are no longer allowed on the CMA field.  This is due to issues with lightweight BBs (such as the 0.12g found at Walmart) shattering and causing a safety hazard.

CMA Gun Restrictions

All guns must be approved by an Admin prior to use. All players are subject to random weapon checks by an Admin at any time. No weapons may exceed the requirements listed below.

AEG/Gas – Full-auto fire allowed – Min engagement range 20ft
BB mass_____FPS

DMR Class – Semi-auto fire ONLY – Min engagement range 40ft
BB mass_____FPS

BOLT-ACTION – Min Engagement range 75ft

FPS charts are for informational purposes only.  All guns must be chronoed with .20g BBs, regardless of what weight is desired for gameplay.

CMA Gameplay Rules

These rules exist to provide a safe and efficient environment for Center Mass Airsoft members and guests. By attending any CMA event you are agreeing to abide by all rules and regulations. Failure to comply will result in ejection from the event and may result in a ban from all future CMA events.

  • Attitude: Airsoft is a game of honor and integrity. Participants are also expected to respect others, personal property, and the field.
  • Game Admin: The Admin is responsible for coordinating events and promoting safety. The Admin will communicate game play types and can impose any additional rules or restrictions to facilitate specific games or scenarios. If a conflict or discrepancy arises between participants it should be taken to the Admin for resolution. The Admin will make the final decision on any issues. Arguing with the Admin will result in ejection from the event.
  • Sportsmanship: Fighting of any kind, acts of malicious aggression, or mental intimidation will not be tolerated. Players who fail to conduct themselves in a sportsmanlike manner will be ejected from the game.  
  • Bans: Extreme behavior, excessive rule violations, or arguing with an Admin may get you banned from any and all CMA events.  Players who are banned or ejected will not receive any refunds.
  • Eye Protection: Eye safety is paramount. Full-seal ballistic eye protection must be worn anytime a player or visitor is outside of a Safe Zone. Eyewear must meet ANSI Z87.1 standards AND seal around the face. Goggles or masks with some type of material filling the gap between the lens and face are generally acceptable. Prescription glasses and safety glasses are NOT acceptable. The Admin must approve all eyewear prior to gameplay.
  • Safe Zone: The Safe Zone is the only area where it is permissible to remove eye protection. No weapons will be fired in the Safe Zone. Participants must remove magazines from guns, clear the chamber of any rounds, and engage the gun safety before entering a Safe Zone. Safe zones will be defined by the Admin and are subject to change. The parking area is a permanent safe zone.
  • Blind Man: In the event of a real world emergency or injury, yell “BLIND MAN!” If you hear someone yell “Blind Man” you should respond by yelling “Blind Man”, ceasing gameplay, removing your magazine, and placing your gun on safe. The Admin will inform players when the situation has been resolved.
  • Hits: A player is hit anytime a BB makes contact with their body, clothing, or gear. Once a player is hit they will yell “HIT!” loud enough for their opponent to hear. Yelling other words or phrases is not acceptable. Do not overshoot your opponent. After yelling “HIT” a player should raise their gun above their head and display a red “dead rag.” Not calling your hits is cheating; cheating will not be tolerated.  Players will only receive one warning before being ejected from the game.
  • Blind Fire: Players must be looking down the sights/scope of their weapon when firing. Holding guns around corners or above their heads is not acceptable.
  • Friendly Fire: A hit is a hit, it doesn’t matter which team caused it.
  • Physical Contact: Never. Under no circumstances should you touch another player. Melee weapons are not allowed.
  • Safety Kill: Does not exist on the CMA field. 
  • Dead Players: Dead players do not talk, do not give away the positions of others, do not complain, and do not fire their weapons. Dead players can only say “Dead Man” if asked a question by teammates. 
  • Wildlife: Do not engage any wildlife.
  • Boundaries: Borders and boundaries will be defined by the Admin. Boundaries are subject to change throughout an event and may depend on the current game style. Players are not allowed to climb on anything including trees and artificial barriers.  
  • Spawns: Spawn points will be designated by the Admin. Spawn camping is not allowed; do not shoot players who are re-spawning. Do not linger in a spawn point.  
  • Fencing: There is barbed wire within the AO. It is marked with yellow caution tape or yellow spray paint.
  • Terrain: For safety reasons, do not engage an opponent helping someone up a gully or ditch. Wait until your opponent is on stable terrain before engaging. 
  • Grenades: All grenades must be approved by an Admin prior to use. Any grenade that goes “bang/pop” has a 10 ft hit/kill radius, regardless of the shape of the shell. A hit can be avoided by hiding behind hard cover sufficiently large to hide the player.  Trees and other players do not count as hard cover.  Any grenade that ejects BBs must strike the target with a BB to count as a hit. Grenades must perform their intended function in order to count as hits; duds do not kill the target.
  • Smoke/Pyrotechnics: Smoke must be approved by an Admin prior to use. Pyrotechnics and fireworks are not allowed.
  • Gun Restrictions: All guns must be approved by an Admin prior to use. All players are subject to random weapon checks by an Admin at any time. 
  • Rentals: If you borrowed/rented any item, do not mess with it. Consult the owner for any adjustments.
  • Police: Real world law enforcement officers may enter the area at any time. This is a potentially dangerous situation. Airsoft guns look like real weapons and Police will treat them as such. If Police arrive, cease gameplay and obey their instructions immediately.
  • Hydrate: always drink plenty of water, regardless of the weather or temperature.
