Fn Ps90 Review [2021]: Rare and worth it?

In this FN PS90 review we’ll be covering the FN and its specification. We’ll check out the pros and cons of this Bullpup Rifle to determine whether it’s the right choice for you.

FN P90 Background

The FN PS90 is the civilian version of the iconic P90 military-grade firearm.

So have FN managed to successfully adapt the iconic rifle in the form of the PS90, and have they managed to retain the iconic look and performance of the military version.

The first thing you need to know about the FN PS90 is it is a bullpup rifle. This is the popular, compact form of rifle which has found favor among certain parts of the firearms community.

However, bullpup rifles aren’t universally loved, and their compact construction has led to performance problems with certain bullpup rifles and shotguns. So have FN managed to learn from the mistakes of others with the PS90, or does it have problems of its own?

If you’re thinking of making the PS90 from FN your next bullpup rifle, you’re going to want to check out the full Gun University take on the PS90. We’ve found a few facts you’ll absolutely want to be aware of before you go any further.

Let’s get to it!

FN PS90 – Our Take

The FN PS90 is the most innovative bullpup we’ve reviewed.

Seriously, just look at it! It looks way ahead of its time.

It feeds a tiny cartridge that sits perpendicular to the barrel in a magazine ABOVE the action of the gun!?!?! It has two ergonomic holes for grips?!?!

What we loved: Tiny package bullpup “rifle.” We used rifle in quotes because although it is legally a rifle, it is on the small end when it comes to power. There are handguns that shoot this same cartridge. It’s fast and it easily penetrates body armor but it doesn’t have much power behind it (and nearly every other rifle round penetrates armor just as well or better).

What we didn’t like: The manual of arms for this rifle is too awkward for us. Sure, if you switch to a bullpup rifle from a standard rifle, you’re going to have to get used to manipulating the firearm a little differently. However, this just takes it to a new level… it’s cool, but weird.

Here’s the harsh truth, aside from its “cool factor,” this gun doesn’t really hold up against its competition… it’s not “better” that anything else in any single category.

Unless you’ve got to have one because you like it in a video game, stay away from the FN PS90.

FN PS90 Pros and Cons

Let’s face it. The FN PS90 is a pretty novel gun. Aside from the Steyr Aug, it may be one of the most recognizable bullpups out there. But it takes more than good looks to shoot straight.

Best Sight for the FN PS90

The FN PS90’s unique design allows for you to utilize a taller sight than most bullpups–especially since it’s sight rail sits so high. And trust me… you’re gonna want a sight for it. Oh, and if you’re gonna need a sight mount plate (depending on your model), check out Design Machine P90 Mounts.

TRIJICON MRO

Check amazon Price

If we’re recommending an MRO sight mount, it only makes sense that our Editor’s Choice is the Trijicon MRO. This optic is a solid green dot sight with an adjustable 2 MOA dot. The sight is nitrogen filled making it fogproof and submersible up to 100 feet. However, we really don’t recommend taking your gun that deep. CHECK IT OUT ON AMAZON

Best Sling for the FN PS90

Once you’ve got your sight mounted, there isn’t much left to do as far as customization goes for this gun. But if there’s one thing any rifle needs… It’s a quality sling.

VIKING TACTICS WIDE PADDED SLING

Check amazon Price

At roughly 6.5 lbs, the FN PS90 will start to weigh down on you if you’ve got to hand carry it all day. And plus, its unique design doesn’t necessarily lend itself to being hand carried well. This might be why the folks over at FN integrated a sling mount into the gun. We prefer popping on the Viking Tactics Wide Padded Sling for optimum comfort while carrying. CHECK IT OUT ON AMAZON

Other Bullpup Rifles of its Class to Check Out

When it comes to bullpup rifles, there are much better options out there. Sure… the FN PS90 looks cool. And it’s probably on your favorite video game. But we just don’t think it’s really worth the value. Here’s two different alternatives:

Apart from the need to have specialized magazines and parts, the Steyr Aug still remains as a top choice for anyone looking to purchase a bullpup rifle. Why? Because it just looks cool! Seriously, lots of bad guys in movies uses this gun. On top of that, it’s just a very reliable choice for a bullpup. Price would be the only downside but worth it if you can afford it…READ MORE

This is our favorite bullpup rifle we’ve gotten our hands on. It shoots reliable and accurate.Also, it fires common ammo with easy to find mags–unlike the PS90, As a matter of fact, the thing we liked the least is its price. But… you do get what you pay for…READ MORE
