FNH PS90 Review and Operation
What is it?
. Let's start off with what this gun is. It is a PDW (personal defense weapon). It is by law a rifle (16" barrel and has a stock), semi-automatic, and operates by blowback (which means it is not gas operated). Blowback operation gives you more reliability (less parts to break) and faster rate of fire (bolt does not have to wait for gas to unlock it so it can reload) at the cost of bullet velocity (reloading process can start before bullet is completely out of the barrel).
. This weapon shoots 5.7mm x 28. The idea is to be as effective as 9mm, and have the capability to penetrate kevlar body armor.
. Above I told you what the gun is. This gun is only built for one purpose: close quarters battle. Everything about the gun is perfect in that aspect. The magazine sits on top of the weapon making it more portable and harder to get hung up on something. Each magazine can hold 50 rounds which cuts down on how often you have to reload. Recoil from firing is very minimal. You can stay on target after each trigger squeeze.
. This gun is only good for shooting up to 200 meters. It is not designed to be a field rifle. It is essentially a .223 bullet with a smaller casing. The only available ammo to the public (from FN at least) is the frangible and hollow point types. Armor piercing ammo is NOT illegal, however they do not sell it to the public for PR concerns. Many shooters load their own full metal jacket bullets into spent casings. I personally shoot SS197, which is a 40 grain frangible bullet. It can be bought for around $19 per box of 50 rounds. This ammo used to be very expensive, but as 5.7mm has started becoming more popular the price has reduced dramatically. (check my "ammunition and where to get it" for links)
. Since it is built in the bullpup configuration (trigger is forward of the hammer, and feeds from behind the trigger), it is very easy to shoulder. I am going to go ahead and say that this weapon feels like the lightest weapon that you will ever fire from the shoulder.
. There are three models in all. One comes with a triple rail. It has no optics, but does have a rail that can be used to mount any aftermarket sight on. One comes with a built-in sight that runs off of ambient light, and finally the model I have (PS90 USG) which has a black reticle and does not require any kind of lighting. I chose it because I didn't want to have to buy an aftermarket sight, and the fiber optic sight model has issues with being hard to see in various lighting conditions.
. This gun has only seen about 200-300 rounds fired through it so far. I normally shoot it at 50 meters. So far it has not had any jams or problems. I don't really plan on shooting this gun much anymore, because I am wanting to store it for Z-Day. It really feels like you are shooting a pistol when firing it. It came zeroed PEFECTLY out of the box, and I haven't even had to touch the sights. It also comes with iron backup sights located on the left and right sides of the primary optic.
. Probably the most interesting part of the whole weapon is the magazine. Obviously it sits on top of the gun. The weird part is how the rounds sit. They all sit inside the magazine sideways. As the round gets closer to feeding into the chamber, they are rotated in line with the barrel and then fed. It looks like a problem area, but I haven't had any kind of feeding issues.
. Standing and shooting unsupported at 100 yards, you can very easily put all 50 rounds on a paper target when taking your time with each shot. This is BY FAR the easiest weapon I have ever fired while standing up. It's a little hard to shoot off of a bench because there isn't much gun to rest on the table. But, this weapon was not designed to be shot off of a bench. For what this gun was truly designed to be used for it's perfect, however it is not for everyone.
. I am going to give the final score in two parts:
For what it is designed for, I give it 5 out of 5 zombie heads:
For use as a primary weapon on Z-Day, 3 out of 5
I am only rating it 3 out of 5 for primary weapon on Z-Day because the ammo would be hard to find if you weren't already stocked up on it. The only other guns that shoots this ammo in existence are the FN FiveseveN pistol and the AR 57 rifle.
Before field stripping, remove magazine and make sure the chamber is clear.
WITH MAGAZINE REMOVED, pull charging handle back to **** the hammer.
Depress receiver latch and remove receiver/barrel assembly forward out of gun.
Tip gun downward and slide the bolt assembly out.
Push up on the recoil pad and remove.
Grab hammer pack tab with thumb, press up on tab, and slide hammer pack out the rear
of the gun.
Final disassembly should look like this: (notice how the rounds sit inside the magazine)
The safety is full ambidextrous. Rotate clockwise for fire, counterclockise for safe.
1. Corrective Action: This is not coming from a FM or anything but using what I know about Army steps I'll improvise. (There is no forward assist so SPORTS is going to have to be modified)
o Immediate Action -- If weapon fails to fire, S.lap down magazine to make sure it is seated, P.ull back charging handle, O.bserve the empty or dud round eject from the ejection port, R.elease charging handle, and attempt to fire again (S.queeze).
o Remedial Action -- If weapon still fails to fire, remove magazine, pull charging handle to the rear, and inspect the chamber and bolt face for any obvious problems. Reinstall magazine and charge weapon, attempt to fire.
o If weapon still fails to fire, then turn it in to the armorer :)

I love the compactness and solid look to these rifles. Haven't got a chance to fire one yet, looking forward to it though. Got a question though, aren't you limited in mag capacities

Pictures are up, but review will have to wait until after the weekend. When I get some time I'll write up a thorough review and operation info.
