I am about to buy one, but have some newbie questions:

How do you keep from blinding yourself and team mates while using a full power IR laser.

What doe the .mil do?

For training how can you be sure that the russian switch that puts it in an eye safe power mode is really doing that?

what is the Minimum safe distance for eye damage with a 20mw IR laser?

Quoted:

For eye safety, I was able to find green Laser Toric lenses for my Oakley M Frame Alphas off ebay which I now wear whenever I do any night shooting.

Wanted to give an update as I've had my PERST 3 for nearly a year now.

I had to send it back to Moscow a few months back as the illuminator stopped working, VIS and IR lasers still functional. One of my friends has an 07 SOT so we did a night machine gun shoot out in the desert and I put my upper on one of his FA lowers. Don't know if that caused just the illuminator to stop working but its the only thing I can think of. Since I bought my 3 from Zenitco on ebay I talked to Dimitry, he was slow to respond to my messages but he took care of me. Got the "Russian Flashlight" back within a month so good CS. Didn't even have to rezero it when I reinstalled it so it seems like the mount does RTZ.

I've been doing alot more night shooting lately and my 3 is still serving me well. My only complaints now is the illuminator flood level is fixed, lowering the power just dims it instead of adjusting spill. It doesn't want to stay centered with my laser, annoying but I can live it as I use the laser more than the illuminator anyway.

Added a PERST 4 green + to my collection from Ivan Tactical when they were right about $400 this past Black Friday. Got out of Russia and cleared customs just as fast as my 3 did about a year ago. Haven't mounted it to anything yet as I am debating if I want to mount it to my BCM midlenght that I rarely even shoot anymore or spend the money on a Zenitco railed handguard for my SAM7SF so I have an AK I can use at night as well.

Last night I brought my still in the aluminum can PERST 4 and my Holosun LS321G for comparison and to see if the 4 also has the same circular streak artifacts around the laser like the 3 does. Yes the 4 does it as well, but both will disappear when I turn on the IR light on my now helmet mounted Fenix TK-25IR, or have Illum+Laser on. Not a big deal when it doesn't obstruct my view but worth mentioning. The Holosun is a reliable and capable unit but of course being civilian power pales in comparison to the PERST units. It will be on the EE soon as I'd like to buy another PERST 4, or hopefully they come out with a PERST 5 that improves on the 3.

Those won't protect you from IR lasers, will they? Just green wavelengths?

Quoted:

Can you get a picture of the circular streaks? Mine doesnt do that.

Did they modify your illuminator to no longer be focused?

Just received my Perst-4+ from ebay seller Zenitco. Im going to assume that it is defective but i should probably ask. the green visible is only a "dot" at a foot away from a surface. at 10-15 yards it turns into a fist sized orb. at about 20-25 yards it only gets bigger and hazier turning into about a head sized orb. changed the batteries and checked all physical characteristics to make sure nothing is broken or the lens is obscured and everything is fine. I emailed the ebay seller and he responded right away saying something along the lines of "dont use it on a close surface" regarding the major surrounding splash but did not address the orb shape and hazy nature.

Quoted:
Took these in my spare bedroom, dot is much sharper in person but will give an idea of what Im talking about. NOD is TNVC PVS-14 Gen III. I was wearing my Laser Toric lenses for this test.

Helmet mounted Fenix TK-25IR IR illum on, notice the artifacts is washed away, black shadow on bottom left is a leather office chair

Visible green + laser, PERST 3 is mounted right behind MBUS Pro front sight which is what the shadow is

Anyone else has this on their PERST as well? Again not a big deal to me as it doesn't impede my view of what Im aiming at, but it is something worth mentioning

@TxZen or anyone else with a Perst-2....what have you been getting for battery life on a fresh charged Russian 18650?

The P2 comes with two, and all four powered up my two P2 units upon arrival, but I'm wondering if I should top them off, or just run 'em until dead like NiCad rechargeables.

Any chance these things won't get a memory if charged before completely drained? Thinking yes, but welcome input from others as I'm not a battery guru beyond knowing that I don't keep alkaline batteries in the house any more except 9v in the smoke detectors that get changed every 6mos.

Just got my Perst 3 in from a December order from Ivan

Quoted:

Mine has the artifacts around the IR illuminator too. My friend that has a full power i2 with the IR illuminator also has artifacts so I guess it is common across high power laser illuminators.

Quoted:
I fee like an idiot here after having my perst 3’s for over a year now but if I am reading those last posts right the illuminator is adjustable? As in the beam spread?

Quoted:

Yes. You can focus the beam.

Quoted:



I've always thought they were a little tight, but I use them just for clip on work. Guess that makes sense now.

Does the perst 3 emit a visible red light when ir is turned on?

Quoted:

Your plug is different than mine (Green Standard) - is yours the Red Gen 1 they had for ~$850? Or is that the Gen 2 plug, and I got Gen 1? Doesn't matter, just curious. I don't recall the circle of the illuminator moving around, but I didn't really pay attention - just unscrewed it all the way, then put it back on all the way. I centered it over the designator, and the adjustment screws were stiff'ish, which is good.  

Quoted:
Yeah I got the Gen 1, hell of a deal considering they were going for more than 1k before the gen 2 came out.

Just got my Perst 3 in from a December order from Ivan, Russian holiday rush meant it was a 2 month weight but it is what it is. Put it on the krink for a photo op, will be going on my 14.5 when thats done. Illuminator sure blows away my M600V vampire I have on my sbr along with my Perst 4, finally being able to just press 1 button and get both laser and illum is so much better than haveing to mess around with 2 tapeswitchs overlayed thats for sure. Has anyone else noticed the illuminator seems to move left to right around when focusing it? Not sure if it was just from me messing around with it or what but I won't know for sure until i get it all zeroed. The switch feels great but I do wish I could make the unit momentary on only or something, don't care much for the pulse setting.

So, i saw one poster say his tape switch does work as a momentary. I tried with my PERST-3 last night and found it does work as a momentary switch, just has to be held down for a bit before releasing... maybe a second or so. So, you can't just "blip" it for a split second, but it does seem to work as a momentary...

Play with it and report back!

Perst noob here

Looking to get one for an ak105 I'm putting together

Is the perst3 the illuminator laser combo?

Perst4 looks like it's just a laser.

How does the perst laser/illum compare to a peq15 in function and ease of use? I'm assuming pretty simple so the russkies can figure it out

Quoted:

Yes the Perst 3 and 2 are laser/illuminator with the 2 having a white light as well.

It is quite simple. My manual has no English and I figured it out pretty quick

It isn't just any girl. It is Anastasia.

If you don't care about red vs. green laser you can find the PERST-3 red with the gen 1 plug for under $900 before shipping online whenever they come up for sale. I think Ivan Tactical is the one that was carrying them. Not sure if they still have them in stock.

Another option is you can go with the PERST-4 (IR and visible laser) for $400 along with the Klesh-2 (IR and visible light) for $370. Then you would need the ZenitCo KV-4/2 dual remote pressure switch for $67. So about $830-840 before shipping.

Just depends if you want it all in one unit or don't mind going with sepwrate light and separate laser but using one pressure switch for both.

Quoted:

I use Full power peq 15’s now along with a 15-a (dbal a2)

The perst is great and I do like the controls. They are simple and easy to mess with in the dark.

The available switchology on the peq’s give you a lot though. Aka the ability to run the taps or whatever your switch of choice is along with your surefire.

I have a few of the gen 1 perst plugs and they seem fragile. My gen 2 plugs seem better, but not great. Of course I haven’t had one fail so I guess it’s just a feeling so far.

Quoted:

The cable wire type connector vs the QD gen2?

What concerns do you have besides your feelings?
