P90 fans have been running the same basic shape for years. The EMG x Strike Industries SI-90 finally changes it. It's a licensed airsoft version of Strike Industries' P90 modernization kit, first shown on the real-steel side in 2024, and it comes in four flavors: a gas blowback, a brushless AEG, a standard AEG and a cheaper Sportline AEG.
The detail that matters most for longtime P90 owners: according to WMASG's breakdown of the lineup, the AEG versions are built by King Arms with EMG, Evike's in-house brand that holds the Strike Industries license. King Arms already makes one of the better-known P90 AEGs, so the SI-90 isn't a new factory learning the platform from scratch. The gas blowback version comes from WE-Tech, built on its existing P90 GBB.
What Strike Industries changed
The SI-90 keeps the P90's bullpup layout and top-loading magazine but fixes the parts people complain about. EMG's product pages list revised grip ergonomics with a different grip angle, fully ambidextrous controls, an adjustable cheek rest, Picatinny rails on the bottom and rear, and a handguard with M-LOK slots at 9, 11, 1 and 3 o'clock. The receiver carries licensed Strike Industries roll marks.
It's still compact. EMG lists every version at 580mm long, and the bullpup layout leaves room for an inner barrel of about 240mm, longer than most SMG-size airsoft guns.
SI-90 AEG (standard and brushless)

The electric guns run a full-metal Version 6 gearbox with a quick-change spring system, so tuning power doesn't mean splitting the gearbox. WMASG says they use 9mm bearings and an E-Shooter Kestrel ETU, and EMG lists 360 to 380 FPS on 0.20g BBs.
The trigger works like the real P90: a half pull fires semi, a full pull goes full auto. Pull the charging handle back and the hop-up door opens to a rotary adjuster. The included 100-round midcap works with other P90-series AEG magazines, which matters if you already own a King Arms or other P90 AEG. Power comes from a 9.6V P90-type NiMH or a 7.4V 1500mAh LiPo, wired to the rear.
EMG lists the AEG in Black and Dark Earth, each with a brushless motor option, plus a "Raider" bundle. WMASG puts the standard AEG at US$349 in short or long stock, and the brushless version at US$449 in short stock only, expected in September 2026. The brushless gun shares the same body as the standard AEG pictured above.
SI-90 Sportline AEG

The Sportline is the budget pick. EMG lists a reinforced polymer upper receiver and frame instead of the standard model's aluminum upper, and WMASG notes a different top rail. The internals are the same Version 6 gearbox setup, and EMG lists slightly higher velocity at 380 to 390 FPS. WMASG puts its pre-order price at US$180, expected in September 2026. WMASG doesn't say who builds the Sportline.
SI-90 GBB

The gas version uses metal internals for the bolt, barrel, hop-up, charging handle and trigger bar, and runs on green gas with a 50-round magazine. EMG lists 380 to 400 FPS and a weight of 2,220g. WMASG says it's based on WE-Tech's P90 platform and puts it at US$499, expected in September 2026.
Which one to get
If you already own a P90 AEG and a stack of midcaps, the standard SI-90 is the easy upgrade: same magazines, better ergonomics, an ETU and quick-change springs out of the box. The Sportline is the cheapest way into the shape, and the GBB is for players who want recoil over magazine capacity. Prices above are US prices from the sources cited, and Philippine pricing will depend on local importers.
