I’ve been trying to clean up and sort out all the junk I have. Then I figure out excuses to not get rid of any of it.
In my digging around, I found a right angle flash light. Then I found another one. Last time I saw one of these was on Mel Gibson in “We Were Soldiers”.
We wore ours on the non-firing shoulder.
Back when I was in boot camp, I was issued one of these. Actually, they gave me one and billed me for it. So I should say that I was forced to buy one. I thought it was so cool.
Says U.S. MX-991/U, but the Fulton website calls it a “N47”
We used these a great deal when I was in boot camp and school of infantry. Firewatch would patrol with them on and the red lens installed. Road guards during runs would wave them to (hopefully) get the attention of traffic. And we would wear them on our 782 gear.
This 2 D-cell battery flash light had several features which I thought was just great.
In the battery compartment, under the spring, was an insert that held a spare bulb. It was good that they designed it to carry one, as I remember often having to replace the bulbs. I’d steal bulbs out of the spare compartment of other Marines (or recruits during boot camp), to keep my light running. In the cap under the compartment there are colored lenses. Blue and Red were common. I seem to recall seeing yellow lens at some point in time, but I may be mistaken.
Up at the working end, there is a second bezel that can hold the colored lens in. On green light, a light I used while I was in the Corps, these lenses still have my initials written on them with a Sharpie. If I recall correctly, I started doing that because my red lens kept getting stolen and I would have to steal someone else’s red lens. Finally I started marking them.
I only ever saw green angle flash lights while I was in. Some years back I bought a foot locker, and it had some clothing and gear in it. There is where I got this black angled flash light.
The brass controls and clip come blackened from the factory. You can see that I wore the black off the controls on the one I used while I was in. It has a sliding switch for on and off, and a very very stiff button for momentary usage. We often clipped this light to the metal loop on the Y harness of our 782 gear.
The fact that it was waterproof, had multiple controls, the ability to change the color of the output, and it carried it’s own spare bulb. There would have been a time I would have told you this was the coolest piece of infantry gear. I used it a little after school of infantry, but then when I learned about the Surefire 6P, this was pretty well forgotten.
In lieu of red lenses, in Iraq we picked up little keychain lights with red LEDs like the one above to use. I still have the one I carried in Iraq in 2006, and it still works. I’d snap a picture, but it is somewhere in the pile of junk I was moving around.
These angle lights are pretty well obsolete, but they had a good run.
Long ago I had this idea. I was going to use a Surefire weapon light and an Eotech 553 and then all I would need is CR123 pattern batteries to run them. I would then be able to use rechargeable CR123s and save money.
This was before I learned first hand how bad Eotech sights are. I also contacted Eotech and Surefire and asked about rechargeable batteries. I got a hard NO, with terms thrown in like, “melting”.
A CR123 puts out 3 volts. Some of the RCR123 can be charged to the point where they are putting 4.5+ volts each. Put a pair of those in an electrical device that is not designed for it and you might cause catastrophic failure. So that killed my plans back then. Fortunately that got me into Aimpoints.
Now, a good bit more battery powered devices are designed to use rechargeable batteries, and there are new sizes of batteries. A little while back I sold several older lights and I picked up a Surefire M600 Dual Fuel light that uses a 18650 rechargeable battery. It can take 2 CR123s for a slightly lower output, but one rechargeable 18650 out performs them. Now, there is also the Zenitco Perst-2 which has an Green Laser, Slaved IR Laser, IR Illumination, and a 740 lux light that uses the 18650 battery. One battery could run a high performance Surefire weapon light or a Perst-2 combination device.
This just seemed awesome to me. I sold a bunch of older stuff to update to this new versatile configuration.
But then those bastards screw me. Turns out, that the 18650 battery is a very loose standard and almost each company making them makes them different lengths.
Over on the Candle Power Forums there is even a chart made by HKJ about it:
I was never completely happy with the DBAL-i2, so when I learned about the Perst-4 I decided I wanted to get one to replace my DBAL-i2.
DBAL-i2 (Model 9003)
Green Laser 532nm <5 mW ClassIIIA
IR Laser 850nm <0.7 mW, Class I
Uses 1 CR123 Battery
3.5L X 2.75W X 1.59 H
1cm per click at 25m
PERST-4 Gen 2 Green +
Green+ Laser 18mW
IR Laser 850nm 20mW
Uses 1 CR123 Battery
90x60x37mm (3.54 X 2.36 X 1.46 Inches)
220 g (7.76oz)
1.5cm per click at 25m
Each come with a tape switch. The DBAL uses an Insight pattern tape switch compatable with the PEQ-2/4/5/15, etc. Surefire offers a dual switch that will work with the DBAL and a Surefire light. The Perst tape switch is the best I have ever used.
The tape switch with the PERST has a brightness knob, allowing you to switch between 5 brightness settings on the visible laser and 8 on the IR laser. It has a cross bar safety that can lock out the tape switch. Both sides of the rail clamps have 2 screws, so you can clamp to out of spec rails or simply loosen one to mount to a rail. It has a quick detach 3 prong proprietary attachment, which would be my own concern about a weak spot. I’d worry about something hitting that attachment and breaking it.
Prices vary, but shopping around I generally saw the Perst-4 as $200 cheaper than the DBAL.
Ok, now to the big picture. The DBAL-i2 is from a German Company (Steiner) and built to meet us specifications for eye safe lasers. For at least half a decade now it has been the standard over the counter Visible and IR laser aiming solution for the commercial consumer. It works, but it has it’s flaws. Some of them drain their batteries when off. The visible and IR lasers are not slaved, so each has to be zeroed separately.
Now believe it or not, but our FDA doesn’t regulate foreign lasers, so more powerful foreign lasers can be imported. Like the ZenitCo Perst series. The Perst-4 is their equilivant to the DBAL, a visible aiming laser and an IR laser. But they are slaved on the Perst-4 so if you zero one the other should (as long as it isnt broken/defective) be zeroed as well. Major time saver, much easier to zero an visible laser than an IR laser.
The next big thing is that the Perst-4 is sooo very much more powerful than the i2. More power isn’t always good in the IR world. This means that these lasers are not safe for your eyes. Imagine having a gun that is constantly shooting, you don’t point it as your self or at a direction where a round might ricochet into your self. Same with these high power lasers. Higher power isn’t always better. Up close it can bloom and cause all sorts of glare. When the low power IR lasers started coming out, the early adopters started to point out that they were often better for indoor use than the high power units. That is why the Perst-4 has brightness adjustments.
The DBAL has external click adjustments. The Perst has capped adjusters that require a tool like a coin. Both have a top button for turning it and off. The Perst also has an addition button on the back that does the same. Tap the DBAL button for momentary, double tap for on. On the Perst tap is on, double tap sets it to strobe. I don’t care for the strobe function, but it would have some use. A little note, the top button on the Perst has a tactical click while the back button doesn’t. I find the Perst button easier to use than the DBAL’s button.
Both take a single CR123 battery from the front. The cap is much easier to open on the Perst. The DBAL cap is retained with a strap.
The operation/lock out switch is on the back of the DBAL, and the top of the PERST. Initially I didn’t care for the one on the Perst as it was very stiff, but after messing with it for a day I find it is much easier to use now. The NK marking is the IR laser, the 3 marking is the green laser. The DBAL has a green light on the back to show when it is on. The Perst has a red light for the visible laser and a blue light for the IR laser.
The Perst has the rail mount built into it. The DBAL uses a throw lever QD mount, It uses the same pattern as the ARMS17S pattern. This mount makes the DBAL taller than the Perst. The DBAL will protrude into the view of an optic due to that extra height.
So, what is the catch or the downside of the Perst? First it is from Russia. While ZenitCo is known for taking care of their customers, being a Russian company imports or support may be cut off. All the controls and the manual is in Russian. Fortunately the Perst-4 is pretty simple. Uunlike the i2, the Perst-4 is most certainly not eye safe. While you can dial down the IR and Visible Lasers, it appears it lowers the output by pulsing them, not reducing power. So when the lasers are dialed down, fast movements appear to be dashes instead of lines, and the laser it self is probably still not eye safe. The Perst beams have some glare or splash coming from the emiters, not as clean a projection as the DBAL.
Those might be deal breakers for some, but I can live with it. I’m going to be selling my DBAL and using the Perst in it’s place.
Night vision is expensive. Then, there are all sorts of options, but they are sold by competing dealers so it is hard to find fair comparisons about them. It is true force multiplier as every day we experience darkness and the vast majority would not have something like night vision. It is also something that people won’t be throwing together in their garage after a SHTF event. You either have it or you don’t.
Not that long ago a night vision salesman was pushing a product I was really interested in. Then he started making all sorts of impossible claims. Made me decide not to buy from him. It can be hard to sort through the marketing bullshit, especially if you have limited knowledge or experience with night vision.
NITEWALKER posted an excellent comparison video of various Dual PVS-14 bridge mounts. Not a whole lot of people would get the chance to have their variety of sub $1000 bridge mounts on hand. That why I am so grateful to see this sort of information shared. No way would I be buying all that stuff.
