Marui SG553 Plus AEG

The Marui SG553 Plus AEG is a modern evolution of the proven SG553 platform, based on the Swiss SIG series. The Plus version offers enhanced internal technology and new features for maximum reliability, precision, and user safety.

The receiver is made from reinforced polymer, combined with a sturdy handguard featuring four integrated 20 mm Picatinny rails (top, bottom, sides). The matte finish ensures a realistic appearance and high-quality feel. The folding stock and compact design make the SG553 Plus ideal for use in confined spaces.

Technically, Tokyo Marui introduces the new PLUS system: An integrated FET and microcontroller manage the electronics, optimize motor performance, protect circuits, and ensure faster, more reliable trigger response. The system also prevents damage from overcurrent or faulty batteries. The rifle supports both 8.4 V NiMH and 7.2 V MS-LiPo batteries.

The adjustable hop-up unit and precise barrel manufacturing guarantee excellent range and accuracy. Thanks to the 14 mm CCW thread on the barrel, silencers or tracer units can be easily installed.
