A High-Performance Close-Range Rifle with Exceptional Precision and Reliability. The SG 553 is a Swiss-made assault rifle and carbine developed by SIG Sauer (now Swiss Arms) as part of the SG 550 series. It is a compact variant of the SG 551, designed for special forces, law enforcement, and military units requiring a shorter, more maneuverable weapon without sacrificing reliability or firepower.
 
The SG553 Plus joins the Electric Gun Plus series, which is compatible with MS Li-Po batteries! Featuring the PLUS System with an integrated FET circuit, this model enhances safety and improves trigger response in semi-auto firing. Based on the SIG552 SEALS, the SG553 Plus has been upgraded both internally and externally for superior performance.
 
Key Features
 
FET Circuit Integration
A hybrid switch combining mechanical and FET elements reduces current loss at the contact points, ensuring faster trigger response from pull to BB ejection. Additionally, this enhances switch durability for extended use.
 
PLUS System
The PLUS System incorporates a microcontroller unit (MCU) that monitors and controls the FET, battery, and motor. It not only optimizes motor rotation but also detects abnormalities and halts operation if necessary, significantly increasing safety.
 
Enhanced Durability with Reinforced Polymer
The handguard, upper receiver, and lower receiver are constructed from reinforced polymer, providing greater rigidity compared to traditional resin components.
 
20mm Rail System for Customization
Equipped with a lightweight rail handguard featuring four mounting rails (top, bottom, and sides). The upper receiver also includes a 20mm Picatinny rail, compatible with a variety of tactical accessories.
 
Matte Black Finish
The receiver, stock, grip, and handguard are coated in a matte black finish, enhancing the realistic look and premium feel of the rifle.
 
Flip-Up Sights
Front and rear flip-up sights can be folded down when using optical attachments. The rear sight is also adjustable for elevation.
 
Muzzle Options Compatibility
Comes standard with a CNC-machined aluminum flash hider. Removing the flash hider reveals a 14mm counter-clockwise threaded muzzle, allowing for suppressor attachments and other muzzle devices.
 
Transparent Magazine Design
Includes a 40-round transparent magazine, allowing users to visually confirm remaining ammunition. The magazine is equipped with a new follower system that ensures smooth feeding until the last round.
