Sekito Co., Ltd. presents two electric airsoft models from BOLT Airsoft, the MP5 J and the MP5 SD6 Shorty. These models are built with steel frames that include welding details intended to replicate the appearance of the original firearm. The MP5 J features a three-position retractable stock, while the SD6 Shorty is designed with a more compact suppressor. Both units weigh between 2.7 and 2.8 kilograms, providing a balanced weight distribution for the user.

The internal battery is housed within the handguard, and the hop-up adjustment is located behind the charging handle. The charging handle functions with a full stroke, allowing for manual operation techniques common to this platform. A specific feature of these models is the recoil system, which can be engaged or disengaged depending on whether the user prefers tactical feedback or battery efficiency. The guns are compatible with 120-round magazines that feature a modern design.

A performance test at an outdoor mountain field shows the guns maintaining a steady trajectory at various distances. The internal mechanisms consist of reinforced gearboxes and metal components built to endure the mechanical stress of the recoil system. Maintenance support is provided by the distributor, who offers individual replacement parts for repairs. The presentation concludes by noting that other versions of the MP5, such as fixed-stock models, are also available in the lineup.
