Introducing the “SG553 Plus” in the electric gun Plus series that can use MS Li-Po batteries!
The PLUS system (FET circuit) provides high safety and improved trigger response during semi-automatic firing. Based on the standard type electric gun “SIG552 Shields”, the “SG553 Plus” has been upgraded both inside and out to a higher level of operability.

• Equipped with FET

  Equipped with a switch that combines mechanical and FET. Compared to a mechanical switch only, there is less current loss at the contacts, improving the response from pulling the trigger to firing the BB bullet. The durability of the switch part has also been improved.

• PLUS System

  We developed the “PLUS System” in which a microcontroller unit (MCU) comprehensively monitors and controls the FET, battery, and motor. This system not only controls the rotation of the motor, but also detects any damage or abnormality in each part and stops operation, making it a safe system.

• Increased rigidity with reinforced resin

  Reinforced resin is used for the handguard and upper/lower receiver, providing increased rigidity compared to conventional resin parts.

• Equipped with 20mm wide rails

  Equipped with a lightweight rail handguard with mounting rails on the four sides of the handguard. In addition, a rail is also provided on the top surface of the upper receiver, allowing various optional parts compatible with rails with a width of 20 mm (Picatinny standard) to be attached.

• Black Finish

  The receiver, stock, grip, handguard, etc. are painted black with a low gloss finish, giving the gun a more textured and solid feel.

• Flip-up Sight

  The front and rear sights are flip-up types that can be folded down when using optical equipment, and the rear sight can be adjusted up and down.

• Compatible with various muzzle options

  The flash hider is made of machined aluminum and is standard equipment. If you remove the flash hider, you can attach a muzzle option with a 14mm reverse thread, such as a silencer.

• See-through magazine

  It comes with a see-through magazine that holds 40 rounds and allows you to see the ammunition through. It also uses a new follower that allows you to fire every last round.
