If I am posting this in the wrong area, I apologize in advance.

I have owned my PS-90 for about a year, and have changed the light/ laser setup on it several times in attempt to find a "sweet spot." The equipment I currently have for it is a 1" diameter light, and an Aimshot green laser, white ring sight with REM-3. The carbine for all intents and purposes is for LE work, and I will have an Urban ERT sling shortly.

So my question for open opinion; should I use a Promoted Pawn double rail on the right side, light on top/ laser on bottom, or (1) rail on each side of the optic with devises mounted?

I am thinking that going each side would "look nicer," yet it places an object into the operator's field of view. I get the idea from pictures that the double rail may be less "tacticool" yet may offer me more usable function should the carbine be used under real world stress.

Comments are very welcome here, please offer yours!

I have one rail on each side like most, which does look cooler, however it makes the weapon much wider. So wide that it wont fit in my case with both of them on. Most cases are not thick enough, usually you have to get a cloth type, and even then it's a tight fit. I have to remove my laser to get it to fit in my case. If I had 2 rails on the one side, then both laser and light could be on all the time and fit in my case. So the way it stands now, if someone broke into my house, I'd have to politely ask them to wait so I can put my laser on! I may have to consider getting the 2 rails one side setup.

Excellent thoughts here, thank-you!

Please keep the opinions coming, I would bet that this idea has been contemplated by many owners of this platform.

I am highly focused on my belief that as I aim with my right eye, through non-magnified optics, I will shoot both eyes open therfore allowing my left eye to track other targets, ect.

The reason I am asking all of this is that surly there are members here that are useing the proposed double rail setup. Do users of a similar setup find that they have better field of view, or is this idea of a blocked FOV something I am overthinking? This is a firearm that may in it's lifetime, be called upon for a real shtf, and it does go to work with me in the squad car semi-often.

I just pulled mine out and checked as I have never given it that much thought. The laser does indeed block my fov a bit. For close quarters its not a big deal. If an armed suspect is close to you, you may not see his left armpit, but everything else is visible and you will see him. But if you were looking down a long alley or large warehouse full of large crates, and the suspect had his head pop up from behind a crate to see you, his head would appear to be only about a 1/2 inch tall from a distance. So it is possible that if you were scanning ahead of you and he popped his head when your laser was there, you would not see his head. I tested this with a coffee mug on my counter. There were times that it was blocked by my laser. I tried with 1 eye and 2 eyes opened. Naturally it was worse with 1 eye opened. With 2 eyes it was way better, almost non existant. However, if I really tried I could place the laser so it still did block my fov even with 2 eyes. But I wouldn't be too concerned about it, as when I was doing this I also noticed that the Ps90 barrel, my watch, even my hand could potentially be blocking my fov if the object was far enough away and in that perfect spot. You just have to keep your eyes active to get a "stereo" visual. With your job it wouldn't hurt to to place both laser and light on one side to be safe.

I suppose on afterthought, if both were mounted on one side, while using a (2) point sling, it might be easier if the carbine were slung over ones shoulder while transitioning to handcuff ect. where two hands are needed. With the double mount, the attached items would be away from ones back in that instance vs with two rails, one attachment would be between the user and the carbine.

Have U seen my review of the Double Rail mount? It is in the Product Review section.

It is here:

http://fnforum.net/viewtopic.php?t=5966

If you want to mount 2 items, I'd use the double rail mount, but have a 3rd rail on the otherside just to make the gun look nice. But leave that side empty.

If U carry the gun at the range, or wherever, using a sling - you will soon find out why you should leave the inside side of the weapon accessory free.

Excellent read Shipwreck! I wonder if it would be possible then to place a single low profile rail on the left side and install a QD sling mount to it? That would make a clean setup for a double point sling, detach from the front quickly for a single point setup. Would the Urban ERT sling work like that?

U would have to order an extra part from urban ERT for as few dollars, and then buy the metal piece to attach to the rail for the sling to snap to.

But, it is a waste to do that.

Urban ERT's 2 point sling already attaches to the receiver itself - hust below where the side rails sit. And, you can unclick the buckle to detach from that point. It is essentially what you just decribed, done a better way.

Also, as the receiver is aluminum - i don't think using the side rails as a sling mount is a good idea. Over time, U could strip the screw out possibly.

For you i would say the double rail on whatever side you like your attachments on, for me i chose a single rail but i already had a streamlight M6 light/laser combo to put on it

Just to throw a second option out there, I was advised by another member to look into a product made by LaRue Tactical. It is called a double stack light mount, and other than a picture I do not have any first hand knowledge of it. It does appear that if is a throw lever double 1" mount that would lock onto a single PS-90 rail. It does look like a clean setup, but I am mostly interested in keeping things as close as possible to the carbine at this time. I use a low profile rail, and I do not know if the mount would clear the bolt lever that close to the receiver. I will look into this more, it would be very useful to have a quick throw mount.

Offnote-It is quite expensive.

I have rails on both sides, light on right, laser on the left. I look through the sight with my right eye so the laser is in front of my left but it causes me no problem. I'm focused further out at the target anyway.

I carry on a 1 point (from vestguy) and the laser does not interfere with my gear. This is on fairly long hikes in rough terrain so I'm generally holding the gun with my off hand as well - this keeps the left side away from my body but even when I let go of it and it hangs I do not have a problem with it.
