Tokyo Marui's SG553 Plus, the newest addition to their Plus AEG series, launches on February 21, 2025.  This electric airsoft gun is compatible with MS Li-Po batteries and features the advanced PLUS system (FET circuit) for enhanced safety and improved semi-automatic trigger response.  Building upon the classic SIG552 Shields, the SG553 Plus boasts internal and external upgrades for superior performance.

Key Features:

• Integrated FET: A combined mechanical and FET switch minimizes current loss at the contacts, resulting in a more responsive trigger and increased switch durability.
• PLUS System: This innovative system uses a microcontroller unit (MCU) to monitor and control the FET, battery, and motor. Beyond motor control, it detects and halts operation in case of damage or malfunction, ensuring safer operation.
• Reinforced Resin Construction: The handguard and upper/lower receiver are made from reinforced resin, providing greater rigidity compared to standard resin components.
• Quad Rail Handguard: A lightweight rail handguard with 20mm rails on all four sides, plus a top rail on the upper receiver, allows for extensive customization with Picatinny-compatible accessories.
• Durable Black Finish: A low-gloss black finish on the receiver, stock, grip, and handguard creates a more realistic and rugged appearance.
• Flip-Up Sights: The adjustable front and rear flip-up sights can be folded down for use with optics.
• Muzzle Compatibility: A machined aluminum flash hider comes standard. Removing it reveals a 14mm reverse thread for attaching suppressors and other muzzle devices.
• See-Through Magazine: The included 40-round see-through magazine features a new follower design, ensuring every BB is fired.
