SYSTEMA Professional Training Weapon System Model M4A1 User’s Manual Revision 1.
Preface Thank you for your recent acquisition of the Systema Professional Training Weapon System. With decades of experiences in making the finest airsoft upgrade components and countless hours of research and development, we are confident that you will find years of excellent and trouble-free service from the Systema Professional Training Weapons.
Chapter 1 — Basic Operations Preparations The Systema Training Weapon Model M4A1 use a high-power, highly customerized rechargeable 7.2v Ni-CD battery pack as its power source. Before each training session, please ensure your battery pack(s) are fully charged for optimal performance. Refer to your battery charger’s instructions on how to charge the battery pack (as well as discharge / conditioning cycles as needed) . Both the battery packs and battery chargers are available from your Systema dealer.
Battery Installations (Continued) After the battery compartment door is removed, locate the battery connector inside the center tube, and extract it out of the stock. Pull the connector lightly to avoid damage to the wiring. Insert battery as shown, ensuring the connectors on both the battery-side and the stock-side lines up, then carefully connect them. The connectors are polarized so they will only fit together in one direction.
Loading the Magazines To load BB bullets into the magazine, first place the provided loading tool over the magazine’s feeding/loading port, and hold it firmly as shown. It is important to only use high quality BBs to ensure accuracy and reliability. Inferior quality BBs may not be perfectly round nor conform to the 6mm standard. Poor quality BBs can cause jamming and should be avoided. Locate the top opening of the tube, and feed BBs into the tube.
Firing First insert a loaded magazine into the magazine well as you would with a real M4/M16. You can ensure the magazine catch is fully engaged by briefly pulling the magazine down after its inserted. Depress the bolt-catch release pad to simulate releasing the bolt of a real M16.
Firing (Continued) The Systema Professional Training Weapon Model M4-A1 is equipped with a collapsible (retractable) stock. The butt stock can be extended or retracted to suit different tactical requirements. To change the position of the stock, simply depress the stock release lever located on the bottom of the stock. This is typically accomplished by a “squeeze” action with the user’s thumb applying pressure on the top of the stock, while the index and middle fingers apply pressure on the lever.
Chapter 2 — Advanced Features Hop-Up Adjustments Hop-up is a special feature that extends the effective range of the Professional Training Weapon by putting a “backspin” on the BB bullet. The back-spin will create additional aerodynamic lift, effectively makes the BB “float” in the air and increases its effective range. ÷ With Hop-Up Without Hop-Up ö For typical in-door, force-on-force training, the engagement distance will be so short that the effect of hop-up will not be noticeable.
Take-down and Maintenance To disassemble the Professional Training Weapon, first punch-out the rear receiver pin until the stopper pin (similar to the real M16) engages. The stopper pin prevents the rear receiver pin from falling out of the receiver, so do not attempt to completely remove the rear receiver pin from the lower receiver. With your palm rested firmly on top of the stock, push the charging handle with your thumb to pivot the upper receiver.
Take-down and Maintenance (Continued) To remove the inner barrel, use a plastic rod (such as the provided acrylic loading rod) and insert it from the muzzle-end. Run the acrylic rod along the inside wall of the outer-barrel until it make contact with the tip of the inner barrel, then push the inner barrel out. Remove the inner barrel by sliding it through the upper receiver, towards the rear of the gun. Occasionally lubricate the rubber seal and hop-up unit from the loading port of the inner barrel.
Take-down and Maintenance (Continued) Caution: While the receiver is in the opened position, DO NOT pull the trigger. If a battery is installed and the fire-selector is not set at “Safe”, the gears will “dry-spin” and potentially misaligning the sector gear. The upper õ Sector Gear receiver will not close when the sector gear is in the wrong position, and major hardware damages can occur if the upper receiver is forced to close in this situation.
