I've got one of these - bought it from Bluegrass Armory for $300. Great optics, astonishingly bright given 21mm objective lens. Only thing I don't care for is short eye-relief - which appears to be endemic among Russian military scopes, and thus the rubber accordion eyepiece.

Do you know what the stub is projecting from the left of the scope even with the reticule-adjustment knobs? On mine its a truncated cone with a screwdriver slot in it. Actually, do you know anything at all about this scope? All I know is where I got it.

Also: Accordion eyepieces don't work well for those of us who wear glasses. I replaced mine with a Butler Creek flip-open objective lens cover. For a front lens cover I stick a 1" vinyl chair-leg bottom into the hole that the objective lens is in.

Sutro,
That stub is for adjust reticule angle. So, if yours is right don't touch it!
Well, what you wanna know? I've been using this sight for couple years and I must say it's just fantastic!
Reticule:
Down left, range estimate scale for .5m high object. Length of the horizontal line is 10 mils.
Down right, range estimate scale for 1.5m high object. Length of the horizontal line is 22 mils.
Cross hair, calibration point 400m/7.62x39. Upper line is for 100 meters, length 5 mils.
1 mil steps for wind correction.
All mils are russian mils!!!!!
When you calibrate you sight you can use that calibration point (arrowhead), shots should be exactly 24cm above of you aiming point! (from 100 meters)
I hope this helps, and please feel free to ask more.

Thanks for responding. My experience has been same as yours - awesome sight. I paid $300 for mine, which is pretty pricey but still 1/2 to 1/3 the price of an ACOG.

Mine's on a .223 SAR-3, so the 'scope's calibration doesn't work. So I just sighted in at 100 yards with the chevron as aiming point (200 would probably be better) and experiment with the other aiming points. So far has been an interesting demonstration of how much more flat-shooting the .223 is than the 7.62. Anyway...

1. Getting the dumb questions out of the way first: What's a "mil"? And what's a "Russian mil"?

2. Fitting protruding from the left of the 'scope is for adjusting reticle angle? Huh? Never heard of that adjustment: What's that about? I've heard of scopes getting off-centered crosshairs with extreme adjustments, but that's the closest I've heard of anything like reticle angle.

3. This is the only scope I've ever had that didn't have provisions for focusing for one's eyesight. Both target and reticule are in clear focus as-is, but is there some provision for focusing the scope that I don't know about?

4. Do you know the story on this scope: History, who makes it [other Russian optics I've got have a manufacturer and/or place name on them - this has neither], and why? I've read that black Russian scopes indicate manufacture for civilian use, silver/grey indicates military use. This scope is black but sure looks like designed for the military.

5. With a ribbed receiver cover I cannot field-strip my AK without removing the scope. Does your AK have a smooth cover? And, if so, does that allow you to keep the scope in place when field-stripping?

6. Oh, and a trivial question: Every time I adjust the scope I find that one adjustment is backwards from what I would expect (either clockwise for left or clockwise for down), and I don't remember which. Can you same me some ammo by reminding me?

7. The pics of your weapon are very cool. What is it, and how have you tricked it out?

Thanks!

Trajectory of the 7.62x39, like a snowball :D
With .223 you miss half of the fun ;)

1. There are three different mil-systems:
We europeans, use milrads. Full circle is 6283,1853... milrads. -> 1 milrad at 100 meters is 100 mm.
US mils, full circle is 6400 mils -> 1 mil at 100 meters is 981,7 mm.
Russian mils, full circle is 6000 mils -> 1 mil at 100 meters is 100,5 mm.
No big deal, but if you have to estimate distance which is more than ½ klick...

2. Sorry my mistake, reticule angle can be adjust with those TWO subs which are on the top and on the bottom of the scope. With that stub from the left side of the scope you can remove the input lens.
( I have only russian manual and my russian is little pit rusty)

3. Nope.

4. It's made in Belarus by Belomo. PO3,5x21 is standard issue of Russian SF. All military scopes which I have worked with have been blacks. Yes, I've seen those silver/grey ones but all in civilian-life.

5. I have the same "problem". I have this "custom-made" high mount which allows me use the fixed sights also but every time I remove the cover I must remove the scope first. That takes about 1 second, so...

6. I've calibrated this scope only ones (it just keeps it) and I must say same like you, can't remember.

7. SAKO M92S (7.62x39) with TR8 reflex silencer. M92S is very common rifle here in Finland.

Thanks for the info!

Your Sako may be common in Finland, but it'd be worth a fortune over here. Lovely gun!

Stock on your Sako is very much like the ACE stock I put on my SAR-3, so I presume you have the same problem getting a cheek-weld that I have. My plan is to put on a detachable cheek-piece: Is there a detachable cheek-piece available for Sakos?

Also wondering what you do for lens covers on the 'scope. I'd found that 1" vinyl chair-leg tips fit perfectly into the objective lens recepticle and into the rubber eyepiece. I've since replaced the rubber eyepiece with a flip-open lens cover.

Didn't quite understand your explanation of what the stubs on the 'scope body are for, but bottom line is that it sounds like they're for things that I wouldn't want to do so long as the 'scope is working OK - and mine works perfectly. Did I get that right?

[M92S]

1MOA out-of-the-box accuracy! Whole sh** cost about $1k (rifle, scope, silencer, sling) :D

There is a cheek-piece, never test it but they say it's quite good. I'll try to find pic of it.

Haven't find any good covers yet, we don't have the same menu available than you have.

Sorry my rotten english.
If it ain't broken don't fix it, yout get that right ;)

(these are factory made stuff)

[Sutro]

If you can obtain a cheek-piece for the Sako I'd very much like to buy it from you. Since it's not a weapon there shouldn't be any legal problems with sending it through the mail.

Any plug an inch in diameter will serve as a dust cover for both lenses of this scope. I just happened to use ones designed for the ends of chair legs. Even a cork would work, although it would look very weird.

...and your English is SPLENDID compared to my Finnish. (Actually, it's good in itself. I didn't know you were from outside the US until you said you were from Finland.)

[M92S]

I'll let you know if I can find that cheek-piece.

Thanks, english is quite easy language but technical or visual context is the hard part, for foreigner.

[Sutro]

And my understanding is that Finnish is one of most difficult languages for an English-speaking personn to learn because it's one of the few languages that isn't of Indo-European origin. Which brings me to...
Is "Suomi" the correct name for the Finnish people, country, language, or all 3?

[M92S]

So they say and they say a lot, don't they :D

Well, Suomi=Finland, suomi=finnish, suomalainen=finnish people.

Interesting and educational discussion on the PO3 5x21. I have the Kobra and POSP 4x24, but was looking for something different. I noticed that K-Var is now offering the PO3 5x21 for $229. I'm also considering the PKS-07 which Centerfire Systems is offering for $199.

[Sutro]

Fergus, one thing you may want to keep in mind in making your selection is that the lower the power of the scope and the greater its field of view, the more rapid is your target acquisition [Kobra, while not a scope, is a good example: Very low power, very wide field of view]. One of the reasons I bought the PSO 3.5X21 is that it has the lowest power and largest field of view that I know of among Russian optics.

K-Var now has the cheapest price on these. K-Var of all people!
