I have one of the red laser gen 2 models but no other real experience beyond that and a Streamlight TLR VIR II.

There is a fairly decent thread on the Perst models on arfcom. Consensus is they are powerful (outrageously so) and built like tanks. I’m very new to NV and being in Canada have dipped my toes in with the digital SiOnyx Aurora.

If your questions are about physical features etc I can help but can’t help you with comparisons with other lasers.

Yes. And a few others I know followed me into it. Even made my own manual (not on this computer, so remind me!) with some hints about how it works since they are vague, wrong, or badly translated in the manual it comes with.

It is legit mil gear, Perst 3 seen on Russians (and Little Green Men) in Syria, Crimea, etc. Talked with the sales rep, and it's so poorly marketed, has the weird features to us westerners because he's barely supported. Zenit makes mil stuff, but doesn't mind if some of their guys sell some on eBay. They just won't make a version for the US market, so it's what he gets off the line.

Not Steiner quality, but competently made. Good laser optics, decent tracking for zero, decent switches. Legit off (leave batteries in it), tactile main controls (confidence / verifiability in off, or mode selected). Remote is a bit odd, but is included and usefully has things like power level dial. Whole unit appears indestructible. I have had mine rained on, snowed on, iced up, heated up, covered in mud and banged around, and shot the gun it's attached to plenty. No change in zero, always works. Looks new still really so even the anodizing and markings are good quality.

Biggest upside is power for price.

Biggest downside is power. NO eyesafe lockout, so know what you are doing and that you need high power before getting/using one. Easy to suffer eye injuries from high power lasers. I made a cover/diffuser/protector for the laser side (then, keep it closed when not lasing... for safety) but it's not designed for that so is sketchy to get it to stay on.

Get the green viz side. More usable at dusk, etc. I mean, if you will need a pointer. If just for aiming: who cares?

If you need illum, get the Perst 3 as stated. Same unit, with illum strapped to the side. The 4 is very small and offset a bit right, so ignore how the 3 looks bulky. Mounted, it evens up with illum left, laser right.

If you see an "old model" skip it. Get the screw cap battery port one. Lube the battery o-ring, etc.

Other oddities like weird mount (not RTZ, not even captured nut!) and the shipping. Oh, the shipping! They have no packaging. Zero. None. Comes in bubble wrap, maybe. The factory is convinced that it is so bombproof it doesn't need a box, but it looks so unprofessional.

Are there ideal sources to acquire them from?

Got mine from Oleg here in the US. He seems to be the main supplier of Russian imoported optics although I dont have his contact info Im sure someone does. Honestly no idea about battery life. Uses C123s and never had one die. Its not the kind of thing I have it on for more than seconds to a minute at at time. Change them every so often before a hunt.

Agree about battery life. Infinite? Dunno. Never run out. And I use the laser kind of a lot.


We got all ours via eBay, but it's not not-legit. It comes from Zenit (looked up the shipping address, customs paperwork, and yup it's an office building on their little campus in Moscow), it's just not imported on a mass scale, and that's why we get high power. A "fully-legit" distributor would get noticed by the FDA then we couldn't buy them.

This is the Zenit Co eBay account: https://www.ebay.com/sch/zenitco/m.html?_nkw=&_armrs=1&_ipg=&_from=


A handful of russia-centric deailers carry them as well. These say they are in stock and have a hell of a sale price now! https://ivantactical.com/shop/weapon-accessories/flashlights-and-accessories/flashlights/zenitco-perst-4-dual-visible-ir-laser-designator/ When I was buying, all these were out of stock, had long lead times (meaning: they also just call up the Zenit guy), and/or were much more money than direct ordering.

My manual for your enjoyment.

One thing I cannot get from them is the power level at each setting. Would help with understanding eye safety, etc. if we had that. If anyone knows that, or anything else — or has a meter! — do tell and I'll add to the manual.

If anything else seems missing, you are right. I didn't do instructions on e.g. mounting as even when I asked it's essentially just "screw it on, duh." No suggested driver, no torque specs, etc.

You gave a good review. I have a couple of the Perst-3 models and like them a lot so far.

Would like more info on how you made cover diffuser. The pointer is almost too powerful, a diffuser would certainly help refine/focus the point. I had kinda wondered if it was something we could get https://mkmachining.com/ to make. Would love to see a pic of what you came up with.

Thanks.

“Legit” enough for me haha. Perhaps I used the term too loosely...

I’ll use the source you mentioned once I get around to picking one up. Hadn’t really considered buying one until I saw your review.

Kickass stuff with the manual too. 🍻

I can get photos sometime. Just got a cheap chicom 1" flip up Butler-creek style cap. Yup, the tube the lasers come out of is perfectly 1" in diameter Wire tied it on tediously so it won't come off, but there's enough surface area a clamp on would hold well.

I drilled a couple holes in the front, and glued some diffuser material on. Then, it's serviceable as a close range (indoor range) illuminator if needed. But also, did diffuser vs cover so if I leave it on I can immediately see "oh, cover is on" vs wondering why no laser comes out at all, start checking switches, battery position, etc.

I would totally buy a purpose-made cap. And be happy to share more on my thoughts/use of this. Make it happen!

Enh, tired of talking to people after business hours. A few photos:

Korsak, OTAL, MARS, PERST4, PEQ2



With cover. Wire tied the cap to the spare retention spot. POORLY. Cap is a bit rubber, nothing I had would make a clean hole. I do not think this wire retainer trick would be needed for a made-to-order cover, but it is nice it's there, might be worth using as well if clamping (plus tape, rubber?) doesn't seem solid enough. You can also see the holes in the cap, barely.


With the remote visible. Since like zero sales sites tell you about that. Remote attaches to pic rails which I do not run ont he side so I did velcro, wire ties, bike tube, etc. It works well enough for me. Wire goes back out of sight to keep strain down. I added a foam tube around it as a strain relief as it has none, is sorta in midair vs the rest of the forearm.


If you need another view, unmodified (pre-cap) from the other side:



Post-getting-dirty one day. I hosed off all my stuff on the deck after this :)

And then I made the cap for the optics because man does that seem risky now.

Nice! And thanks for the pics.

What did you use for the diffuser material?

Um... milk bottle. Like the 1 gal jugs. Sorta embarassing as I have SO much specialized plastic, lens materials, etc, but tested a bunch (even some official white light diffusers) and that worked best.

It's PE so... it fell off. I need to go re-attach it sometime. Thinking I'll stop trying to glue it, just silicone trap it on the edges.

Hahaha, I never would have thought to use that. Thank you for the info!
