Laserex Laser Install (with text description and pictures)
Gentlemen, I do appreciate your input and warning about the lower power. I am sure the military grade laser is much better. I was already aware of the power restrictions but I purchased one anyway to evaluate it's performance. I wanted to determine whether or not it is of good enough quality to install in my PS90.
Allow me to share my experience:
I purchased the laser from Den Trinity after reading on their websight that it is in fact a Laserex P90 laser. I understood that it is not the military power model but that it is identical in every other aspect. The laser arrived in packaging marked P90 Laserex with an additional Quality Endorsed Company Standards Australia sticker. I opened the package and compared the laser system I received to the one in the photo of the split open P90 LV shown in this forum. The components are identical which is what I expected since it is the same Laserex P90 laser system with a lower power (civilian legal) laser. I did notice a minor improvement on the one I received. The wires leading from the activation button to the laser power setting switch were bound in a flexible tube instead of loose. I also observed that the battery compartment for the one I received has a black finish. The battery compartment for the one in the P90 LV photo appears identical without the black finish. The black finish on the one I received doesn't appear that durable though. However, I don't know of any finish that sticks to brass very well.
After powering it up, these were my observations:
The laser has three settings (Low, Off, High). It uses one 3V CR123A lithium battery (Standard size like in the Surefire and Streamlight lights). First I tested it indoors on the low setting. It appeared as bright as just about any other laser dot device. I then tested it indoors on the high setting and the laser was extremely bright. I would definitely say the brightness level compares to the Streamlight M6 laser. Indoors in a dark room, the laser was bright enough to light your area. The next day I tested it outdoors in Texas daylight. At a distance of about 100 feet, I could still see the dot on the side of a red building. However, the dot was not readily seen. At around 50 to 75 feet in daylight it was quickly spotted on a variety of different backgrounds. I did not test it any further than 100 feet.
My intention for purchasing the laser was to use it indoors or in low light environments where the stock sight is not at it's best. I am already satisfied with the performance of the stock sight in the daylight. I am not satisfied with the performance of the stock sight indoors or in low light environments. I believe this laser will "fill the gap" for me. It may not meet your requirments but it meets mine and maybe some others.
I do have photos of the laser I received but I can't post them. If someone would like to post them, I'd be happy to email them to you.
Posted by btown02: The information supplied by U378:
1. The stock must be disassembled by removing the
crossbolts. You will notice the strengthening ribs in
the stock which were not present in the earlier P90 LV
photo. The stock already has slots in place for the
laser wires.
2. I placed the front laser "cap" on the end of the
stock to mark it's postition. When drilling on the
seam, I had to use a very small drill bit and increase
the size gradually to prevent binding. I increased
the size till the laser "lens hood" could just fit
through the hole.
3. After inserting the "laser hood", I placed some
folded newspaper behind it to hold it in place and
reassembled the stock. With the hood held firmly in
place. I pressed the laser "cap" on the hood to
determine the position of the three cap mounting
screws which thread directly into the laser inside the
stock.
4. I then opened the stock and placed the laser inside
to determine the placement for the "power setting
selector." I marked the location, reassembled the
stock, and drilled the seam (again increasing bit size
gradually) until the appropriate size was achieved.
Keep in mind, the top surface of the power setting
selector must be mounted flush with the top of the
stock. Otherwise, it will bind when the receiver is
inserted. The way I accomplished this was by
recessing the top of the hole slightly with a
reloading case deburring tool.
5. I then marked the locations for the laser actuator
button and battery casing. I approximated the exact
location for the button after studying the P90 LV
photos found on the interenet. The battery casing
mount slides on one of the bolt guides so I just lined
it up and marked it.
6. After reassembling the stock, I carefully drilled
the button hole and battery casing hole (again
increasing bit size gradually). The battery casing
hole is quite large and I did not feel comfortable
using that large of a bit on the seam. So, I slightly
increased the size of the hole with a half round file
until the casing fit snug.
7. I opened the stock again, inserted the laser
components, and reassembled the stock.
I am certain that I did not use the correct technical
names for the components. But, I'm sure you can
figure out what I'm talking about.
The laser adjusts for windage and elevation by
tightening and loosening the front cap mounting
screws.
Also, just a warning. The plastic cuts and files VERY
easy. Be careful not to make the holes too big.
And the disclaimer..... I am not a machininst or a
professional gunsmith. Use this information at your
own risk.

FN FiveseveN Forums - Who makes the integrated laser?
FN FiveseveN Forums - Who makes the integrated laser?: "Can't see how taking it apart would void the warranty, there is nothing inside to mess up. Besides the SBR conversion I am going to do will take care of the warranty.
By the way all you need is a 3mm hex key to take it apart. It just pulls apart after the bolts are taken out, and believe it or not nothing comes flying out at you when it's done!! You know like springs, pins ect."

FN FiveseveN Forums - P90 Laserex Internal Laser
FN FiveseveN Forums - P90 Laserex Internal Laser: "This is information I found while looking into what it would take to put a P90 Laserex internal laser into a PS90.
In searching for PS90 parts and accessories I saw a review on installing the Laserex Laser Sight in an airsoft P90. The review said they used a real P90 Laserex Laser, so I thought maybe we could use some of the info on installing it into a PS90.

Where they purchased the laser
http://www.dentrinityshop.com/den_search.jsp
Search for �P90� �Laser�
So first I contacted Lasermax the makers of the P90 Laser.
They told me the Laserex Laser they sell to DEN Trinity is a lower powered version of the laser sight they sell to FN. They also said if I want the real version of the laser I needed to contact FN in Belgium. I doubt if they would sell to me. I can�t find the spec�s but I thought I saw the real Laserex laser was higher then the 5mW allowed(?). I then asked Laserex if they had any conversion information, they didn�t.
Next, I contacted Den Trinitry Shop Sales and asked them for instructions or a manual on the conversion. They are the ones that sell the �real� P90 laser. They didn�t have one either. They offered to do the conversion for me. I then told them it would be for a real P90(PS90) and not a airsoft P90. They said have never seen a real P90 before so they didn�t know if it would fit. By the way, the cost is around $220 plus shipping.
That�s as far as I�ve gone.
The other way of installing a laser would to be mounting it on a side rail.

Some modifications are required. I think you need to drill a hole thru the front vertical sight mount(for lack of a bet"

FN P90 Laser Target Designator
The FN HERSTAL P90 submachine gun can be supplied with an integrated laser on request. This laser is fully integrated into the receiver without modifying the the weapon's outer shape, balance and ergonomics. The customer can choose either a visible "red dot" laser or an infra-red laser for use in conjunction with night vision equipment. P90 LV (with visible laser) In low light conditions and indoors the laser designator, when activated by a pressure switch, projects a highly visible red dot onto the target. The laser designator can be zeroed so that rounds hit exactly at the point indicated by the laser. This enables the user to aim accurately without shouldering the weapon; he or she can fire from the waist, the chest or with the weapon held away from the body. The laser designator allows very rapid target acquisition, especially at close range and/or in low light. The laser dot also has a theoretically disuasive effect on the enemy who can see that a weapon is precisely aimed at them.
The visible laser designator allows the user to practice rapid target acquisition and instinctive shooting without firing, as the dot indicates the point of impact. P90 LIR (with infra red laser) The infra red wavelength laser designator projects a dot onto the target that is not visible to the naked eye. The user - and the target - must have night vision equipment to see the dot. This type of designator is designed for night use and for operations where maximum discretion is required (anti-terrorist, hostage rescue, covert operations). |
