USE OF THIS MANUAL

Before operating the Airsoft gun, read this manual in its entirety. Important safety topics and tips are discussed throughout all of the chapters. It’s important that the operator know the principles of gun handling, safety, and operation prior to fi ring the Airsoft gun.

SAFETY GUIDELINES

Safety DistanceThe eff ective shooting range is approximately 175 feet. BBs fi red from this Airsoft gun may travel farther than intended. Make certain that you have an adequate backstop.

Eye ProtectionEye protection should be worn at all times when both shooting and maintaining your Airsoft gun. Protect your eyes from BBs under pressure while performing maintenance on your Airsoft gun.

Assume Every Gun is Always Loadednti are certain the cha er is e t treat ever n as i it ere a e n t

ass e the cha er is e t ase n r e r r s e ne e se s r A a s re ve the a a ine an vis a chec t c n r the cha er is e t

Beware of Barrel ObstructionsEnsure the Airsoft gun barrel is free of obstructions before you fi re the gun. Even the smallest obstruction such as dirt, dust, or a stuck cleaning patch can cause a jam, misfi re, or malfunction.

Muzzle ControlAlways keep the muzzle of the gun pointed in a safe direction. Never point the muzzle at a person or object that you do not intend to shoot.

Keep Your Safety OnKeep the gun’s safety on until your sights are aligned on your target and you are ready to fi re.

Keep Your Finger Off The TriggerKeep your fi nger off the trigger and out of the trigger guard until your sights are aligned on your target and you are ready to fi re.

Identify Your Target and BackstopBefore you pull the trigger, make certain of your target and what is beyond it. The Airsoft gun should never be fi red at surfaces such as rocks, glass, water, or other hard surfaces where BBs are likely to ricochet in unpredictable directions.

! WARNING:- Airsoft BBs can be a choking hazard. Keep them away from children.- Failure to follow safety guidelines may result in serious injury.

5

! WARNING:- Adult supervision is required for any person under the age of 18.

SAFETY GUIDELINES (CONTINUED)

Failure To FireIf the Airsoft gun fails to fi re, misfi res, or malfunctions, do not look into the gun barrel. BBs can become lodged into the chamber, and serious eye injury may occur.

Maintain Your Gun ProperlyPerforming proper maintenance, as outlined in this manual, ensures that your Airsoft gun will be safe to shoot and will perform to its designed specifi cations for many years. Alterations, modifi cations or adjustments may damage your Airsoft gun, make it unsafe to shoot, and will void all warranty claims.

Store Your Gun SafelyAlways store the Airsoft gun in a safe place, and out of reach of children. Always transport the Airsoft gun in a carrying case. Never display the Airsoft gun in a public place. Keep the safety engaged, and remove the magazine before storing the Airsoft gun.

NOTE: IT IS YOUR RESPONSIBILITY TO TAKE EVERY REASONABLE PRECAUTION TOENSURE THE SAFE STORAGE AND TRANSPORTATION OF YOUR AIRSOFT GUN.

Orange TipThe orange tip on Airsoft guns help Law Enforcement distinguish the replica guns from their real fi rearm counterparts. Altering the coloration or markings required by state or Federal law so as to make the product look more like a fi rearm is dangerous and may be a crime. Operator assumes all risks and responsibility when doing so.

Hazards of Being Mistaken for a Real FirearmAirsoft guns have been mistaken by Police and Law Enforcement as real fi rearms. A confrontation with law enforcement while carrying an Airsoft gun can result in serious injury or even death. It is strongly advised to operate the Airsoft gun at a safe and legal location. In the event that you are approached by Law Enforcement personnel, you must comply with their instructions immediately to avoid an incident.

Alcohol, Medications, and DrugsDo not handle or operate your Airsoft gun while under the infl uence of alcohol, medication or drugs.

Your ResponsibilityYour Airsoft gun is well-engineered and manufactured to the highest standards. It was carefully inspected before it was packaged and shipped from our factory. Its safe use depends on you alone. You are the ultimate safety device. Like many other devices, your Airsoft gun is safe unless handled in an irresponsible or uneducated manner.
