The lens on the sight is installed with O-ring sealing. Water or moisture won’t go inside the sight at all. There is O-rings on the battery compartment and windage/elevation knob as well. Vortex thought this through.

Burris-FastFire-Reflex-Red-Dot-Sight

4. Vortex Optics Strikefire II Red Dot Sight

Vortex-Optics-Strikefire-II-Red-Dot-Sight

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-Holographic-Weapon-Sight

EOTECH 512 is the most holography sight looking holography sight. I know that doesn’t make any sense, but that design of the holographic sight is one of the most used ones in video games and other media outlets.

Build Quality

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 did that. The weight balance on this sight 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 likes to target dead center always. Otherwise, you could also work with the 68 MOA circle around the red dot.

There is total 20 adjustable brightness setting available in this optic. 20 is not a small number. The reticle gets quite bright during the day time.

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 AAA batteries to power up the red dot sight. those battery fills in the hollow cavity of the sight.

Vortex-Optics-Spitfire-HD-Gen-II-Red-Dot-Prism-Scopes

Vortex Spitfire HD gen II is a 3x optics with 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 the sight is super easy. The windage and elevation dials are located in the side and the top. You can easily change them to your need. 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.

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 clarify your needs and then take the sight that matches with your needs.

Build quality. PS90 is an incredible gun with 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. Lens is your second eye. If the eye isn’t good, it won’t provide good vision. That would be bad 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 in 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 on 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 good reputation in the market and has a decent warranty to back up the claims of the manufacturer.
