FN PS90 is a weapon used in many Secret Service organizations and the military. In a sense, it’s an upgraded version of the world-famous P90. The gun is also being used in the game Counter Strike Global Offensive. It’s a great gun for sure. It’s not a long-range weapon.

And how do you determine which is the best optic for PS90? Don’t worry, your questions will be answered in time. Sit down, relax, and enjoy the read.
Our Top 7 Optics For PS90
1. Vortex Optics Venom Red Dot Sight
Vortex is dominating the Sights game for PS90. Fun fact, P90 sights work on PS90 as well. I mean it’s kinda obvious. Vortex is already used to make solid sights for the P90 as well. Now those optics are also being used with FN PS90.
The Lens
It’s a single-glass design with no prism involved. The glass is fully multi-coated with scratch-resistant coating and brightness coating. Everything seen through the sight looks clear and color accuracy is quite insane as well.
Illuminated Reticle
The illuminated reticle has an adjustable brightness setting. There are two buttons on the left side of the sight. Using those you can increase or decrease the brightness of the sight.
Build Quality
The lens on the sight is installed with O-ring sealing. Water or moisture won’t go inside the sight at all. There are O-rings on the battery compartment and windage/elevation knob as well. Vortex thought this through.
The Cons
The battery life could have been better. But when this sight came out, 50k hours of battery life wasn’t the norm.
2. HOLOSUN – HS510C Reflex Sight for Longer Barrels
HOLOSUN makes red dot sight for rifles and pistols. The one here is made for rifles. It’s a reflex red dot sight with unlimited eye relief.
Mounting System
It uses QD mounting clips to mount on top of the Picatinny rail. It’s quite sturdy and sits there tightly. Although I would love to have something more regular. This is fine.
Illuminated Reticle
The reticle is illuminated. You can choose from the 2 MOA red dot or a green dot. Both of them have a 2 MOA red dot at the center and a 65 MOA circle around it.
Battery Life
The battery life of this sight is insanely amazing. It can last up to 50k hours. That’s huge. You don’t need to worry about changing the battery any time soon.
Sunlight Failsafe
This is an excellent feature. It makes the sight go to sleep mode when there is no bright sunlight around it and it will automatically max the brightness under bright light. You can also turn on the sight by shaking the gun around a bit.
- SPECIFICATION - Reticle: Red 2 MOA Dot & 65 MOA Circle; Light Wavelength: 650nm; Magnification: 1x; Parallax Free & Unlimited Eye Relief; Power Source: Battery; Battery Type: CR2032; Battery Life (Hours): 50000; Brightness Setting: 10 DL & 2 NV; Window...
The Bad Stuff
The mounting system is not the best. It’s quite tricky to make it sit right. But once you do, you don’t need to worry about it falling out of the gun at all.
3. Burris FastFire Reflex Red Dot Sight
Burris makes great scope and red dot sights. Their FastFire reflex sight is a wonderful addition to that collection. It’s a Picatinny rail-mounted sight that can be used with spotting scopes or shotguns as well. But we are going to use it with a P90/PS90.
Good Things About Fastfire 3
It’s a reflex sight with parallax-free and 1x magnification. You don’t need to worry about setting it up every time or find out your dominant eyes to hunt better. You can keep both of your eyes open while using this sight. It won’t matter really.
Easy To Tune
The optic is super easy to tune. Windage and elevation knobs are super easy to adjust. You don’t need to spend much time fixing the windage and elevation.
Build Quality
The sight is water and fogproof. The glass is also multi-coated with different chemicals. Cleaning the glass is quite easy. As dust doesn’t stick around there much.
Manual/Automatic Brightness Setting
You can choose from either of these two. With manual setting, you will have 3 levels of brightness adjustments. With automatic setting, the brightness will increase depending on the environment.
Keep That in Mind
The brightness setting could have had some more tweaking. It works fine but would have worked better with more brightness.
4. Vortex Optics Strikefire II Red Dot Sight
Vortex Strikefire II is another 1x red dot sight. Instead of using a single glass setup like other red dot sights, it looks like a scope and performs quite similarly. It looks like a riflescope but it is fixed at 1x magnification to help you with CQB and tactical shooting. If you want to add a bit of magnification to the task, you could opt for VMX-3T.
Build Quality
The build quality is quite good on this sight. It’s not too heavy not too light. Balanced weight distribution and good exterior coating. The coating didn’t seem to wear off anytime soon. It’s waterproof and the inside is nitrogen-purged. Moistures can’t stay inside so no fogs.
Illuminated Reticle
It has 11 adjustable brightness settings in the optic. you can increase or decrease the brightness with the help of buttons on the side. The button feels quite mushy but they work. It’s a standard red dot reticle. Nothing fancy going on here.
Cantilever Is Included
If you want to use a magnifier with this red dot, you can use the cantilever mount instead of the stock mount.
What Should Be!
Windage and elevation turrets should have been more pronounced. It’s usable, but it’s quite hard to work with them with one hand.

5. EOTECH 512 Holographic Weapon Sight
EOTECH 512 is the most holography sight looking holography sight. I know that doesn’t make any sense, but the design of the holographic sight is one of the most used ones in video games and other media outlets.
Build Quality
The construction of this sight is quite interesting. It uses both plastic composite and aluminum in the same sight. It’s not the first time someone has done that. The weight balance on this site is quite satisfying. Despite having a long nose where the battery is held, it’s quite hollow to keep the balance.
Illuminated Reticle
The 1 MOA red dot is for the people that like to target dead center always. Otherwise, you could also work with the 68 MOA circle around the red dot.
There are a total of 20 adjustable brightness settings available in this optic. 20 is not a small number. The reticle gets quite bright during the daytime.
Never Out Of Fight
Even if a part of the glass is destroyed or blocked by something. You can still use the sight with precision. You will need two AA batteries to power up the red dot sight. That battery fills in the hollow cavity of the sight.
- EOTECH HWS Prestige Warranty - Comes with a 10 year limited warranty
Doesn’t Support Night Vision!
It’s one of the very few holographic sights from EOTECH that doesn’t support night vision. It’s a shame, but we can’t have everything at once I guess.
6. AT3 Tactical RD-50 PRO Red Dot Sight
AT3 Tactical RD-50 Pro is a red dot sight with an elevated mounting system. It uses the riser absolute cowitness to increase the height of the sight. Some people like this, some don’t. But it’s there and it’s convenient.
On Point Reticle
The 2 MOA red dot reticle is accurate, crisp, and quite bright. There are a total of 11 adjustable brightness levels that you can play around with. Find the optimal brightness setting for you and set that as your daily driver.

Build Quality
Made from waterproof, the housing is sealed to make sure it’s waterproof. To bold the claim further, AT3 will provide a lifetime warranty as well. The circuitry inside is shockproof. You are more than welcome to go rough with this sight.
What’s Nitpicking!
Riser mount is not everyone’s cup of tea. Then again, most people love the riser mount. I do too. It’s nothing but nitpicking.
7. Vortex Spitfire HD Gen II Red Dot Prism Scopes
Vortex Spitfire HD gen II is a 3x optics with a BDC4 reticle. The reticle is calibrated up to 600 yards out of the box. Of course, PS90 is not capable of firing that far with 100% accuracy. But it’s good to know a 3x sight can fire that long.
Tuning
Tuning the sight is super easy. The windage and elevation dials are located on the side and the top. You can easily change them to your needs. 1 click = 1 MOA movement.
There is also a ring around the eyepiece that you can move around to focus the reticle. Brightness setting buttons are on the left side of the sight.
Illuminated Reticle
The red color BDC4 reticle is illuminated. It’s not illuminated enough to hunt at night, but it’s fairly bright. You can choose from 12 adjustment levels.
Build Quality
The housing of this red dot is constructed from aluminum. It’s durable and waterproof. The inside is nitrogen-purged to make it fogproof. It’s sturdy enough the internals from shock.
Careful with The Turrets!
The adjustment might be a bit hard for newbies. It’s easy enough to do, but you will need to be careful while playing with the turrets.
How To Choose a Sight For PS90
There are so many good options available for this gun, it’s unbelievable. Don’t worry, it’s not rocket science. You will need to find your needs and then take the sight that matches your needs.
Build quality. PS90 is an incredible gun with an extremely durable combat-ready body. If the optic isn’t made from quite similar material, it may not last as long as we would like to. That’s why, grabbing a sight with good longevity is essential. Good build quality ensures longevity.
Optics quality. I cannot stretch this issue enough. The lens is your second eye. If the eye isn’t good, it won’t provide good vision. That would be not good, to say the least. Lenses should have a decent amount of coating. That way it can generate clear pictures.
Battery life. Red dot sights will have illumination. To illuminate the reticle, you will need to use batteries. When it involves batteries, the concern about battery life comes to mind. Most sight will provide an incredible battery life with the included battery. I wouldn’t be too concerned about this. But it’s something to keep in mind.
Warranty varies highly from company to company. Everyone doesn’t have the same policy nor do they like to copy others. Some companies will provide incredible warranties while some struggle to provide good after-sale service.
It all depends on the experience of the company. Take something that has a good reputation in the market and has a decent warranty to back up the claims of the manufacturer.

Design Machine is a US-based vendor that makes red dot sights for our beloved PS90. They take custom orders based on your requirements. Depending on your needs, the Design Machine PS90 mount will vary as well. you could directly mount it on the PS90 or top of an installed optic.
P90 vs PS90
Secret Service P90 is one of the most loved blowback rifles on the market. It gained so much attraction and love it was unbelievable. FN PS90 is an homage to that P90 rifle and an improved edition. PS90 is also quite bigger and sturdier. The firing mechanism and the bullet chamber were improved significantly as well.
Ultimately, you can say PS90 is the upgraded P90. H&K P90, FN P90, and FN PS90, are different names but similar guns.
Can P90 Sights Work In PS90?
Yes, they certainly can. Both of them share the same mounting rail. On top of that, you could install a different mounting bracket and use any optics you wish. I see no reason for P90 sights not working PS90.
Bottom Line
It’s not easy to follow through a gun like the P90 and deliver an equally awesome weapon. But PS90 is quite solid. I loved how there are so many sights available for both P90 and PS90. You just cannot help but mention the P90 every time you talk about PS90.
My inner fanboy was screaming quite hard while writing this review. After all, P90 is a busted gun! Anyway, enough talk about, we were here to talk about the best sights for PS90.
