EMG Strike Industries SI-90 AEG SMG – Compact

Description

The EMG Strike Industries SI-90 AEG SMG – Compact combines the distinctive P90 layout with an officially licensed Strike Industries chassis, aluminium upper receiver and compact Oppressor-style muzzle device. Built for CQB and woodland airsoft, the SI-90 adds modern ergonomics, extensive accessory mounting and an EShooter Kestrel V6 Basic ETU to the proven Version 6 gearbox design.

The compact SI-90 uses a fibre-reinforced polymer chassis with a more vertical AR-15-style grip angle, adjustable cheek riser and rubber butt plate. This revised geometry improves handling from a standing position, while the bullpup configuration retains a short overall profile without sacrificing useful inner barrel length.

EMG Strike Industries SI-90 Features

• Official Strike Industries licence: EMG reproduces the Strike Industries P90 modular chassis with authentic trademarks and distinctive SI styling.
• Aluminium upper receiver: The metal upper increases rigidity and gives the SI-90 a substantial, realistic feel.
• Compact Strike Oppressor: The licensed Oppressor-style linear compensator complements the short front end and can be removed when another muzzle device is required.
• 14mm CCW barrel thread: Standard male threading accepts compatible airsoft tracer units and suppressors, increasing muzzle accessory options.
• M-LOK handguard: The compact Strike Industries handguard provides M-LOK mounting points for compatible tactical accessories.
• Picatinny accessory rails: Top and side 20mm Picatinny rails accept red dot sights, scopes, lights and other compatible accessories.
• 6.05mm tightbore barrel: The tightbore inner barrel supports consistent BB flight and accuracy when paired with suitable ammunition and HOP-up adjustment.
• Rotary HOP-up: The adjustable system controls BB backspin, allowing trajectory to be tuned for different BB weights.
• Ambidextrous controls: Mirrored charging handles and an accessible rotary fire selector support both right- and left-handed operation.
• Two-stage trigger: In automatic mode, a short trigger pull fires a single shot while a complete pull activates fully automatic fire.
• Adjustable cheek riser: The cheek piece can be raised, lowered or removed, allowing the shooting position to suit optics and face protection.
• QD sling sockets: Front and rear QD mounting points support practical two-point sling configurations.
• Quick-change spring: The Version 6 gearbox allows easier spring changes when power adjustment is required.
• High-torque motor: A Neodymium magnet motor provides responsive operation and complements the electronic trigger system.
• EShooter Kestrel V6 Basic ETU: Electronic trigger control removes the conventional P90 trigger-bar arrangement, resulting in a more direct and responsive trigger action.
• Programmable firing options: The Kestrel ETU provides configurable modes including three-round burst, binary trigger and five levels of pre-cocking.
• Deans battery connector: Rear wiring provides an efficient electrical connection, with a 7.4V 1450mAh LiPo recommended for convenient fitment.
• P90 magazine compatibility: The SI-90 accepts compatible King Arms and KRYTAC P90 AEG magazines but is not compatible with CYMA P90 magazines.
• 100-round mid-cap included: A 100-round magazine is supplied, allowing the SI-90 to be used without requiring an additional magazine immediately.

Strike Industries Compact Chassis

The licensed Strike Industries chassis gives the EMG SI-90 a substantially different handling profile from a conventional P90 AEG. Its AR-style grip angle and textured grip panels provide a more conventional firing position, while the thumbhole construction links the grip and stock to create a strong, ergonomic body.

A removable compact handguard provides additional space at the front while maintaining the short SMG configuration. Removing the handguard exposes a lower 20mm Picatinny rail, so the SI-90 can be configured as a minimalist P90-style AEG or equipped with M-LOK and Picatinny accessories.

Optics and Accessory Mounting

A full-length 20mm Picatinny top rail provides space for a red dot sight or compact scope, while removable side rails accommodate lights and other compatible accessories. Backup sights are integrated into the upper receiver and rail assembly, providing an aiming option when an electronic optic is unavailable.

The adjustable cheek riser helps establish a consistent sight picture since its height can be matched to the installed optic. It can also be removed when additional clearance is required for full-face airsoft protection.

EShooter Kestrel V6 Basic ETU

Internally, the EMG Strike Industries SI-90 uses a pre-upgraded Version 6 gearbox with Tokyo Marui-compatible internal architecture. An 18:1 CNC steel gearset runs on 9mm bushings, while a polymer piston with a full steel tooth rack and high-torque motor provides a durable mechanical foundation.

The EShooter Kestrel V6 Basic ETU replaces the long mechanical trigger linkage traditionally associated with P90 AEGs. This creates a more responsive trigger system, while programmable three-round burst, binary trigger and five pre-cocking settings allow the firing behaviour to be configured to suit different gameplay requirements.

Compact Airsoft SMG with P90 Performance

The EMG Strike Industries SI-90 AEG SMG – Compact combines P90 bullpup practicality with modern Strike Industries ergonomics and extensive customisation options. Its compact dimensions suit CQB and confined environments, while the adjustable HOP-up, 6.05mm tightbore barrel and electronic trigger system provide the features required for broader skirmish use.

Supplied with a 100-round mid-cap magazine and QR-code user manual, the SI-90 arrives with the essential equipment required to get the AEG configured for use. For players seeking a modern P90 airsoft gun with licensed Strike Industries styling, programmable electronics and strong accessory support, the compact SI-90 offers a distinctive alternative to the traditional P90 design.
