EMG x FN P90® Airsoft AEG Training Rifle – Krytac

About this airsoft gun

The Krytac P90 is a licensed FN Herstal replica of one of the few genuinely unusual shapes in airsoft: a bullpup personal defense weapon with the magazine lying flat along the top of the receiver instead of hanging underneath it. Almost everything about owning one follows from that single design decision.

What you are actually buying

This is a full trademark build. The licensing is FN Herstal’s, the gun is sold under EMG’s banner, and Krytac does the manufacturing, so the receiver carries genuine FN markings rather than a blanked-out fantasy stamp. If the trademarks are the reason you want it, that is precisely what you are paying for over an unlicensed P90 clone.

EMG’s “training rifle” wording in the product name is a licensing convention used across their licensed lineup, not a statement about the internals. Underneath it, this is an ordinary AEG. A rechargeable battery drives a motor, the motor drives a gearbox, and the gearbox cycles a piston that pushes air behind each BB. That is the same power system as most primaries on the field, which is why it is the default choice for a gun you intend to use all day: consistent shot to shot, cheap to feed, unbothered by cold weather, and accepted essentially everywhere. If you are still choosing between power systems, our AEG, gas blowback and HPA comparison lays out the trade-offs.

The shell is largely polymer, which is accurate rather than a cost saving. The real P90 is a polymer gun, so a heavy metal-bodied version would be the wrong one. A bullpup also puts its mechanism behind your trigger hand, so the mass sits back toward your shoulder instead of hanging out in front of you.

The layout, and what it costs you

The upsides are easy to state:

• Very short overall length for the amount of inner barrel inside it, because the gearbox sits back in the stock rather than eating up space ahead of the trigger.
• Controls laid out to work from either shoulder, which is a real advantage if you are left-handed or if you switch sides to shoot around cover.
• Nothing protruding below the receiver, so the gun slings flat against your chest and clears doorways, ladders and vehicle seats without snagging.

The downsides are just as real, and they are mostly logistical rather than mechanical:

• Magazines are P90 magazines and nothing else. They are wide, flat and top-mounted, they share nothing with the M4 mags half the field is carrying, and standard rifle pouches will not hold them. Work out how you are going to carry them before game day rather than after it — a dump pouch or a general-purpose utility pouch is the usual answer.
• Rail space is limited compared with a modern M-LOK handguard. There is room for the essentials, not for a full accessory build.
• The stock does not adjust. Length of pull is fixed by the design, so if you run a bulky plate carrier or you have long arms, get the gun into your shoulder before you commit to it.

Internals and the upgrade path

This is where the bullpup layout asks something of you that an M4 never does. The trigger sits well forward of the gearbox and reaches it through a linkage, which means a P90 cannot use the Version 2 shell that most M4-pattern AEGs share. The shell, the trigger mechanism and the hop-up unit are all platform-specific.

In practice that splits the upgrade path in two:

• Consumables that are broadly common across gearboxes are the easy half: springs, bearings, motors and the usual wear parts are widely available.
• Anything structural is the hard half. Do not order a gearbox shell, a trigger assembly or a hop-up unit for this gun until you have confirmed exactly what it uses. Assuming M4 compatibility is the mistake to avoid here.
• Getting inside a bullpup takes more disassembly than an M4, so fitting a MOSFET or rewiring a connector is a bigger job than it sounds.

Our airsoft gearbox guide explains what the version numbers mean and why a MOSFET is worth having. The honest framing for a P90 is that it is a gun to run and maintain, not a chassis to rebuild.

Getting it field-ready

• Eye protection is not optional. Every field requires rated, full-seal protection, and no gun is worth an eye. Start with our masks and goggles guide if you do not already own a pair you trust.
• Battery and charger. There is no buffer tube or crane stock here to swallow whatever pack you happen to own; the shell dictates the size, shape and connector. Read the retailer listing for the battery specification and buy to match it, rather than buying first and finding out the compartment is the wrong shape.
• Check the listed velocity against your field limit. Indoor CQB limits are usually far lower than woodland limits, and a gun that chronos fine outdoors can be turned away at the door of a CQB site.
• Buy spare magazines with the gun. Confirm the retailer lists them as fitting this specific model. Do not assume one manufacturer’s P90 magazine will feed reliably in another manufacturer’s P90.
• Use decent BBs. Seamless and polished, from a brand your field sells; our BB weight guide covers what to feed it. Cheap BBs chew up hop-up rubbers and inner barrels.

How it compares to a conventional AEG

The useful comparison is not P90 against another P90 — it is P90 against the M4-pattern rifle most of the field is carrying.

The EMG Noveske Licensed N4 Gen 3 is the conventional answer: the deepest parts market in airsoft, the most widely stocked magazines, an adjustable stock, and rail space for whatever you want to bolt on. If you have no particular attachment to the P90 shape, that is the platform that will cause you the fewest problems.

The EMG x Colt XM177E1 Commando is the other route to a short gun. It keeps M4 magazines and M4 internals, which sidesteps every logistics problem the P90 creates, but it earns its compact length with a short barrel and a collapsing stock rather than by folding the mechanism backwards behind the trigger.

Set against those two, the P90 wins on packaged length for the barrel it contains, on working equally well from either shoulder, and on being something other than another AR in a field full of them. It loses on magazine availability and carriage, on rail space, and on the depth of the upgrade shelf behind it.

Is the Krytac P90 the right buy?

Buy it if you want a P90 specifically. For CQB, for a vehicle or entry role, for a loadout that calls for one, or simply because the layout appeals to you and the FN trademarks matter, a licensed build from an established manufacturer is a sensible way to get one, and the table above tracks the current listing for it.

Look elsewhere if this is your first gun and you want the simplest route into the sport, if you are building a DMR, or if your priority is a wide upgrade shelf and magazines you can pick up from anyone at any field. An M4-pattern AEG does all three of those better.

If it is the one you want, check current availability at Evike, and confirm the exact variant and finish on the listing before you order — licensed replicas are often offered in more than one configuration.
