AK guys: RPK rear sight adjustment?

[Circle_10]

So, I’m trying to figure out what each windage adjustment increment on an RPK rear sight leaf translates into in terms of MOA.
Based on my limited experience with them, the impression I get is that the adjustment increments are coarser than something like, say, the clicks on an AR rear sight. This makes sense as the sights are intended for use on a light support weapon, but I’d like to know for sure as I want to use one on a standard 16” AK. But if the increments really are very coarse, like equating to several inches at 100 yards or something, than there probably isn’t much point to bothering with this.

Does anyone know what each quarter-turn or whatever it is corresponds to?

The part of zeroing AKs I hate the most is pushing that damn front sight drum back and forth trying to get it just right. I want something with clearly defined increments. And when I get two loads of ammunition with surprisingly different POIs in the lateral plane, being able to just jump back and forth between two marked, pre-established zeroes would be much better than having to dick around with the front sight drum every time.

I know KNS makes two models of click-adjustable AK rear sight, that would be like exactly what I’m looking for, and I may end up going that route, but those are $150 and I’ve already got an RPK rear sight leaf in my parts bin. So if what I have on hand will work for my purposes that would be preferable.

Ive had several AK's and a couple with the RPK rear sight.

An AK front drum sight adjustment tool makes adjusting that easy.

I dont know the what the rear RPK windage adjustment is supposed to be but I wouldn't rely on it for anything approaching precision. Your fortunate if the sights aren't canted.

If you require more precise adjustment from your AK / RPK sight system I suggest an optic of any kind.

I didn't want to say it because I thought I'd sound like a jackass or a know it all, especially given Circle 10's broad knowledge of AK systems. But yeah, that.

I don’t really have that broad a knowledge base of AKs really. I just used to be more of an AK guy back when I joined this site….back then I bought guns and rarely ever shot them. When I started actually shooting more I became more of an AR guy, heh.

So based on what I’ve been able to piece together online and my own range experience the other day, I’m thinking that each windage increment on an RPK rear sight on a 16” AK translates to approximately 3.5 inches at 100 yards. So yeah that is not sufficiently precise for what I was hoping to do.

I have the AK front sight tool, it’s not really about the ease of adjusting it, rather it’s about the lack of clearly defined increments. It’s more like “I dunno push it this way a bit I guess…*fire five shots* oops too much, better push it back a little…*shoot again*….whoops too much that way now…”
The whole process gets on my nerves

Fire 10 shots and you may find the pattern centers up. (sad but true?)

I've had many AK's...your trying to slice steak with a machete.

Luckily 7.62x39 is pretty cheap.

The AKM is a powerful submachine gun that can be used like a carbine or rifle and for doing most things under 150M it's fine.

Just get the irons centered and set so the "battle" position works and then shoot what you can with them or add an optic.

Try buying good ammo next time!

No next time. Dont own an AK.

What match 7.62x39 do you like to use?

Just saying. Using shit ammo and complaining about accuracy.

I didn't say match, I said good. Obviously you can rule out Wolf unless it happens to be something your personal rifle likes.

In no particular order
Yugo M67 surplus
Lapua
PPU
GT
Geco

All better than the typical Wolf and Tula.

The other problem is people expect magic. There's this obsession with 1MOA or less. Nor do AKs get sighted in like Western rifles. In reality the AK is no better or worse than any of the legacy rifles. They all get about the same moa. It wasn't meant to ever be a bullseye rifle but it has no problem reaching center mass hits at 400 yards with open sights. All comes down to the shooter

My SLR-104 in 5.45 with iron sights and 7N6 will group about as well as an iron sighted AR with M193, but my eyes do have some difficulty with AK irons so getting those groups is a bit slower and more tedious than with the AR.

Of the 7.62 AKs I have my SGL-21 is the most accurate, that was the one I tried the RPK sight on but it actually seemed like my groups were a bit larger with the RPK sight than they were with the standard rear sight. I had heard the notch in RPK sights was wider but it appears to be the same width as the standard AK notch, so maybe I was just shooting shittily.
I shot my CZ Scorpion at 100 yds with iron sights and Federal HST a couple days later and got better groups than I did with the AK….

Ok.

I agree AK's and SKS's with non-junk ammo (Russian) can shoot about as precise as a typical AR shooting M193 / M855 and clones. But the AR sights do make this easier. An optic evens things up.

I had decent results with Hornady Vmax (later SST) 7.62x39.
