Ak47 advice

[SloChicken]

Just a heads up, a thicker receiver and bulged trunion really isn't a + or -, unless you are launching rifle grenades.

not exactly,

The bulged trunion increased rigidity at the barrel-receiver interface.
The increased thickness of the receiver is stronger and more rigid in general.

this should be obvious.

There is a weight penalty associated with this increased mass, but well worth it IMO

Both of which are important for militaries using rifle grenades, or for rpks. No so much for others.

Wouldnt there be flex on the weakest part of the weapon system the 1mm receiver during recoil? And one would think that there would be less flex if the receiver was thicker? I thought this is the whole reason why the AK platform is looked at as being less accurate than its AR counterpart.

There is plenty of other things making it "less accurate" then receiver flex. Crappy ammo, huge moving bolt, gas system that is *generally* overgassed compared to other rifles, looser chambers, etc.
*edit* I realize the ammo part is a generalization, but you generally don't see AK guys shooting handloads

Lets say you do go ahead and stack up a good AKM vs a good Yugo. I think this huge difference of potential accuracy isn't as large as people are making it out to be. I've seen some very impressive groups shot with 545x39 and 762x39 Saigas.

But to each their own. I'd love to pick up a yugo just because they are damn nice rifles. Hope I can scratch up the change before they start going up in price again.

I understand all the ammo concerns, but When you have a huge bolt cycling on a 1mm receiver you are going to get some flex. Simple logic would put it that with a thicker receiver you would get less flex?

Yes, but in most cases you aren't going to see the results to a level that people like to think they are going to get. This is a wide generalization, I know, but there is more then just one reason why the AK platform isn't a tack driver.

Don't take this the wrong way, but I'm not going to duke it out why a 1.5 or a 1mm is better. There are PLENTY of other threads about that, by people who are far, far,far smarter than I am. If you think a 1.5mm and an RPK style trunion is going to make your rifle that much better, by all means go with it. I think it's overkill and adds very little, if anything to it. If you are really concerned, buy a milled AK.

[AKSOG]

I believe the weakest point that causes flex is the trunnion-barrel mating or the barrels themselves, not the receiver. If you watch videos of slow motion milled rifles you will still see the flex related to the AK platform.

I am not saying that going from a 1mm receiver to a 1.6mm is going to make your AK A DMR but I would rather have it than not have it. So in my book its a plus.

[kcstott]

Geesh new guy. AKM is the proper term. AK 47 is the full auto version

Incorrect.
The AKM is a Russian: Автомат Калашникова Модернизированный; Avtomat Kalashnikova Modernizirovanniy or "Kalashnikov modernized automatic rifle")

They were built as select fire weapons and individual countries limited the select fire system like the Romanian Guarda It's an AKM with the full auto feature removed. Although some Romy G's did infact come with an Auto sear. it an AK and they did what they wanted with them.

Keep your pimp hand strong!

As far as the 1.5mm thing...

Lets also look at the other features most guns with 1.5mm receivers typically have.

In the case of RPKs the barrel is a much heavier profile, which will help with precision. The barrel is also longer which means more flex BUT it also has a much greater sight radius which definitely helps.

Yugos are usually going to have plain steel barrels with slightly heavier profiles vs your std AKM, both of which will make a bigger difference than a thicker receiver.

How about the Veprs in intermediate rifle calibers? What kind of barrel profiles do they have? I know they have the RPK receivers, if they have std AK profile barrels that might be a better test candidate against a Saiga or similar

[Norcalkid]

I have a WASR, works fine and is reliable. Also have a Saiga. If I were to only have one I'd take the saiga. I have seen them going for about $450 recently, so say $550 with all fees. Maybe another $150 to convert. I have bought a rifle from Atlantic (FAL). They have OK service and they are CA friendly but their prices usually aren't the best IMO.
