Input on 4x POSP vs PK-A Scopes for a Saiga

[Niel4]

Looking to scope my converted Saiga AK (.223).

Interested in range shooting 100-300 yds, not so much for hunting.

Anyone have experience with these type of scopes? I am concerned that the pk-a does not have any magnification (for 200-300 yd shots) or rangefinding capability....do these matter?

I am new to scopes/red dots.

POSP's are excellent optics for the money. I had a 4x24 on my AK for a while, and was thoroughly pleased with it. It was surprisingly bright and sharp for a 24mm optic, the reticle is excellent, and the illuminated reticle was top-notch.

The only reason I got rid of it was that I decided an unmagnified Kobra fit my needs better than a 4x scope (I wanted something fast and accurate from 0 to 100 yards, with capability to 200 or so), and I couldn't afford the Kobra at the time without selling the POSP. Mine was the version with the 400-yard ranging reticle, and I really liked it.

I have pretty decent corrected vision, but even so, the hardest part of shooting at 200 yards for me is seeing the target clearly enough to tell where the dot is on the target. That's the trouble with any unmagnified optic (or iron sights), really. If you're looking to shoot at 300, you'll probably want magnification. The place where unmagnified optics shine is in the 0 to 75 yard zone, IMO.

I have the PSOP 4x24 400-meter version on my Saiga, and I am very pleased. The Simminov reticle gives you three easy-to-use aiming chevrons for 100, 200, and 300 meters shooting (Calibrated for 122gr ammo, so if you're shooting 154gr or something exotic, its going to be off), and the range-finder on it is surprisingly accurate.

The scope itself sits at just the right position that if you keep your head in a natural position, and bring the rifle to shoulder in a standing position, it is RIGHT AT eye level. No needing to hunker down to the scope, or anything. BAM! It's there. The body is made out of (cast?) magnesium alloy, and as would be expected of anything Russian, is over-built. Controls are easy to use.

Only down-side is it is on the heavy side. I would say it weighs in in the 16 oz range or so. Add that to an AK with a full 30 round magazine, and its close to 12 very front-heavy pounds.

I've had a 4x POSP from Kalinka for a few years now. I really like the scope,great quality unit. But, I had a problem with mine kicking itslf loose on my Saiga when firing ( yeah, it's got an AK mount, not the SKS mount).
I took apart the locking mechansm and added a very thin brass washer hoping to torque down the connection a little better, but have yet to test it out.

Did you bottom out the adjustment first? If it wouldn't adjust enough to grip the rail tightly, that one must have had a defective adjustment screw or something.

 

[MIL-DOT]

Yeah, I had the bottom adjusted, and it seemed to fit very tightly, but would still jar loose under fire.
I got the same scope with SKS mount real cheap from a buddy before I knew the difference, and it did the same thing. After researching and isolating the problem, I sold the SKS-mount sope and got one with the AK mount, and was surprised/disappointed to find it had the same issue.

 

[benEzra]

Hmmm. I'd suspect either an out-of-spec rail, an out-of-spec mount on the AK optic, or (possibly) grease on the rail. They usually lock up pretty darn tight; they use the same mounting system on quite a few 7.62x54's.

I am too surprised that your PSOP jars loose while firing. I would suspect that you do not have it properly tensioned down.

To torque it, remove the little tab on the bottom of the throw arm, lift the throw arm up and off, and twist that screw a few turns, put it all back on, and put it on the rifle. If done right, you should probably need 15-20 lbs of force to move the throw-arm all the way to the closed position. Also, when putting the scope on the rail, it should not easily slide on, but will need a little effort and cajoling to be pushed on.

See Kalinka's PDA on how to properly mount and tension it, if you have more questions: http://www.kalinkaoptics.com/aitdownloadablefiles/download/aitfile/aitfile_id/16/
