Why do they still make new AKMs with 45° gas blocks? I honestly don't understand.
Are 90° gas blocks really that much more expensive? Because I doubt it
as a pleb who knows nothing about AK pattern rifles, what difference does it make between these gas block types?
>>29209829
90 degree needed on 5.45 due to shearing of bullet from 45 degree hole.
That being said, akms do not need a 90 degree block. There is no advantage.
Because they're modeled after AKMs?
They have wood too, does that bother you.
>>29209849
Yeah but the 90 looks better.
>>29209892
Not him, but what bothers me is that you asked a question and punctuated it with a period.
>>29209816
>Why do they still make new AKMs with 45° gas blocks? I honestly don't understand.
They're mostly from parts kits.
AK74s needed them because the hole being at an angle would shear part of the bullet.
They made all AKs that way in order to standardize, so they could use the same parts and everything's compatible. It's also cheaper to produce, since drilling a 90° hole is less complicated than doing it at a 45° angle, plus it's one less piece of specialized machinery you have to buy.
Looks better imo since it's on the ak100s which imo are the only AKs worth their salt, and imo I'm a huge AKfag.
So are SAR-2's fucked, because they use a 45° block?
>>29209816
Does it really fucking matter when talking about 7.62x39 rifles?
Fuck no.
>>29210202
kek
>>29209988
45 definitely looks better.
>>29209849
Am I wrong to think that if 90° gas block benefits the 5.45, it's gotta have some sort of advantage for the 7.62?
>>29209849
The barrel's gas port was drilled at 90° to correct the jacket shearing issue. The gas block itself does not matter.
>>29210418
The SAR-2 has a 90° gas port with a 45° gas block. The 5.45mm Romanian guns are built this way since the shape of the gas block does not affect the function.
You can't clean them with the standard gas port tool, though. Here's a diagram of a 45° block and port.
>>29212436
would you happen to have a similar diagram of a 90° gas block or the SAR-2's 90° gas port with a 45° gas block you mentioned?
>>29210202
5.56 is the best caliber??
I hate it when people do that, statements with a question mark. Makes me wonder if they know what a question mark is.
>>29210378
Wait, why is 45 a problem? I can't see how that would sheer bullets less than 90.
There wouldn't be a problem in replacing the 90 GB on the Saiga with a 45, right? It's AKM standard?
>>29209816
they are actually cheaper because 90 degree is a straight hole
so it's because of incompetence
>>29213112
Not really, it would just look retarded. But then again, saigas look retarded
It literally doesn't matter because not only does x39 not shear nearly as bad as 5.45, but x39 physically can't reach the distance where it would make a difference, 500yd+
>>29209988
>it's bad because I dont like it
>>29212271
Yes you are, mr. logical fallacy
>>29213287
It would be on a converted one, of course.
>>29213300
Yeah, get a 90 degree gas block.
>>29213304
You mean 45, right?
>>29212436
>leaving slavs in charge of taking pictures
Also, why do all RPKs have 45 degree blocks regardless of caliber?
Is there a 90 degree hole going into the barrel regardless so it doesn't matter?
>>29213299
>7.63x39 can't reach 500 yards
>>29210418
>>29212436
So what's the deal with the SAR-3 then? I bought one recently and I've been kind of flabbergasted that the Romanians clearly had 45 degree gas blocks drilled to 90 degrees, yet for some reason chose to tool up to produce 90 degree ones... but only for their 5.56 rifles.
It's such a strange business decision, anybody know what the point could possibly be? Also dropping my endorsement of the SAR-3 here, I rarely see them discussed but this rifle is fucking awesome
>>29215202
>>29213299
Yeah, that's a pretty laughable claim.
It hasn't even dropped much at 400 yet. I wouldn't even call a chest sized target at that distance hard, only using irons.
>>29215296
Its dropped over 5' at that point. at 500 its down over 10. Not too much past 500, its subsonic.
>>29215308
>Not too much past 500, its subsonic.
And it'll still horribly injure/kill you dead FAR past that.
>>29215308
>Its dropped over 5' at that point
it doesn't feel like that when you just give it a slight kentucky windage lob that feels just inches higher on target
>>29215187
you are wrong
RPK have a 45 degree gas block
RPK-74 and modern 7.62 RPK have a 83 degree gas block
pic related is a RPK with a 45 degree gas block
>>29215410
RPK-203 with 83 degree gas block
i have a RPK-74 cut out pic, dunno where i saved it
>>29210202
It's meant to convey a flat affect?
>>29215433
Well, I have a semi auto rpk-201 in 556, so that's pretty interesting to me since it explains a lot.
>i have a RPK-74 cut out pic, dunno where i saved it
Time to google some stuff... But please post if you find it first.
>>29215250
Bumping for someone to tell me about why SAR-3s have special snowflake FSB and gas blocks.
>>29215669
Why tool up for new parts when the old AKM shit works just fine? Less time and money invested.
>>29215943
Right, that's why it's weird! The Romanians *did* tool up to make 90° gas blocks, but then only used them on the 5.56 SAR-3 rifles, instead electing to drill 45° blocks at 90° angles for use on the 5.45 SAR-2. Why would they do both rather than one or the other? And why use a modified 45° gas block for the SAR-2 when they clearly had 90° ones available for the 3?
Nevermind that they're the only AKs I've ever seen with cast gas blocks and FSB rather than forged. The SAR series are some seriously weird rifles.
>>29215993
Russian blocks are cast, though.
>>29212436
Yes, the broke ass Romanians ghetto rigged their first 5.45s. Nobody else does this. 90 degree hole should have a 90 degree block.
>>29213112
There would be a problem.
Not only would you have to align and then test the gb to make sure that it lets enough gas in with a 90degree hole, but you would probably have to drill new pin holes for the gb. That said, pin groves on the barrel might overlap with newly drilled ones.
Then theres also the issue of gas tube being too short or long depending on which direction you would have to move the gb.
Pic is my hurr saiga with random parts.
>>29216337
Alright. So you replaced your GB with another 90 degree that has the lug on it?
Cool.
