Main Military Weapon of Your Country: Part 12

But it folds?

[Premislyd]

But it folds?

I don't think pistol grips can fold.

[Novislavia]

Oh. Ha ha. You guys thought I was talking about the pistol grip? I was talking about the stock.

[Spreewerke]

Oh. Ha ha. You guys thought I was talking about the pistol grip? I was talking about the stock.

There is a receiver extension on the AN-94. The folding mechanism is in it (pistol grip is below it). The mechanism does not move. The stock folds and its hinge is at the back of this extension. Rather than an internal folding mechanism (like with standard AKs due to the AN-94's guts), the AN-94 had to have this boot just so it could into folding stocks.

Glorious motherland graced me with the right ammunition today.
So I finally decided to make a post outlining the difference between 7.62x39, 7.62x39mmKC, and 7.62x39mm KCM.

To start, an actual real-world photo of 7.62x39mm, 7.62x39mm "KC", and 7.62x39mm "KCM".



Left to right: Incendiary 7.62 KCM, Standard 7.62x39mm KCM, 7.62x39mm KC, and 1960s standard 7.62x39mm.

To start, in my Russian analog, 7.62x39mm was never thrown by the wayside quite like it was in RL Russia. Soldiers receive a cross-training on both the AK-74 family and the AKM family more extensively than they do in RL Russia. In 1974 the AK-74 was adopted as A rifle, but not the mainline rifle. It served side by side with the AKM, though in different units, never blended. The 5.45 today survives in a number of systems and units, but 7.62x39mm remains the active service cartridge in its newest fourm- 7.62x39mm KC.

In the 1990s, the 7.62x39mm received an upgrade by the Vympel plant in Russia (IC, Puzakk Federation) to a Full Metal Jacket Boat Tail (FMJBT) projectile with a slightly heavier bullet of 124.5 grains and a slightly improved type of powder which allowed for a significantly higher velocity: From the original 738 m/s to an improved 800 m/s, a noticeable difference indeed. These rounds later used a polymer coated case and a special, more efficient sealant and primer (the sealant being around both the neck and primer), and a slightly more pure powder which further boasted the velocity of the cartridge to 850m/s. This load became the 7.62x39mm Kursk Concord, or KC, after favorable testing opted the Puzakk Military to adopt it to replace 5.45 in most major rolls.

The new ammunition offered a significant boost over 7.62x39mm in terms of accuracy and terminal effect. This is thanks to a very slight rearward center of gravity, which allows the bullet to tumble when

striking a soft target, and an air pocket in the front of the bullet encased by the jacket, the projectile yaws tremendously while maintaining a very good penetrative ability. In ballistics gelatin tests, it was discovered the projectile began to tumble violently at approximately 202mm of bare 10% Ballistics gel, and continued to tumble for an additional 500mm before coming to a rest some 50mm later, showing an overall penetration of 752.45mm, with an impact of 2,150.66 Joules of energy. This is a highly favorable wounding profile thanks to the diameter and length of the projectile, which produce a fearsome yaw.

In 2004 the 7.62x39mm KC round received a makeover when the Puzakk Arms commission cleared polymer cased ammunition for duty in the Federal armed forces, ranging from calibers of 9x18 to 14.5x114mm. The polymer cased ammunition cut down on weight of individual cartridges by 25%, without needing any modification to existing rifles. This cut the weight of a fully-loaded AK-103 magazine to 589 grams, compared to the previous 739 gram weight of the AK-103 service magazine. Despite initial concerns, heat displacement was not an issue, believed to be due to the higher heat capacity of the metal cap used in the new polymer ammunition. In addition, the rounds external and terminal ballistics saw no negative change, in some instances reports indicated a slightly better ballistic profile.

7.62x39mm remains one of the most used caliber of main military rifles in Terra Firma, and is continuously produced at over 40 plants across the world. Though replacements are looked for, it is believed 7.62x39mm KC will remain in service for a long period of time.

Where's the fire selector?

[Novislavia]

Where's the fire selector?

Ah. I see. Thank you. Do most Russian rifles have the fire selector on the bottom like that?

[Our Most Resplendent Goddess Sen]

Ah. I see. Thank you. Do most Russian rifles have the fire selector on the bottom like that?

No, AN-94 is just sort of batshit and does its own thing. AKs have giant paddle selectors on the side.

That's what I thought. Thank you.

[Sevvania]

In a continuing quest to create a modernized arsenal for use by FutureSevvania in Terra Firma (FutureSevvania being the modern tech counterpart of the canonical, WWII-era Sevvania), I've been toying around in PMG to see what I can come up with. I'm not very good at modern weaponry, though, so I just ended up with what's essentially a 7.62x54mmR M14.



I'm not sure that it'd be worth switching from the Outlander series to this *gestures to image*, but I thought that it looked ok (although perhaps a bit preset-ish). I decided to post it here and see if anyone had any thoughts on it.

Are those polymer cases, or coloured lacquer?

Honest truth? I got drunk and made them out of a blend of stuff I had around and simply covered an actual case I had of 7.62x39 "KC" (just Vymple-brand ammunition) and snapped a photo. It scraps off with a bit of effort.

This reminds me: apparently, because polymer cases don't absorb much heat, the muzzle velocity is much more consistent. Also, the amount of heat the brass case absorbs is likely under 5% of the total heat produced by combustion, so extra barrel heat is indeed a non issue.

Ah, I see. They don't look half bad. I like the colour coded cases.

I was aware of this actually, thats why I wrote it in I beleive we had a discussion on this in May?

Thank you! I intend on making more when I get more circle-cheese, random platic things and food dye.

I opted to keep them. Im going to see if they feed in my SKS, because I am generally an unsafe person and it is bad to be friends with me.

Because I didnt know which looked better to emphasize difference.

I don't remember discussing the improvements in interior ballistics, but I do seem to remember that we didn't have any hard numbers with regards to how much heat was absorbed by a case.

My mistake, going back it seems you are correct.

Here's where I got my info on the heat absorption of a case from. Page 21 of the document puts the heat loss to the cartridge case at 131 calories, while the total heat energy was 2863.9 calories, which gives us a 4.57% heat loss to the brass. This, was, of course, for the 3.0-06 in the BAR, but I don't see any other small arms cartridges heating the cartridges up that much more.

By the way, did your former sniper reply about whether or not he knows the effectiveness of 12.7mm HE rounds yet?

I'd imagine it would be less severe due to the .30-06s tendency to be very fucking hot. Well, at least mine.

He has not. I asked a mutual friend as to his whereabouts and it seems he is "working". I'm asking around to see who might know.

Guys, I've had a... a terrible idea... I... MT Nock Gun in a range of cartridges for :NS: Hunting.

From 5.56mm up to 12.7mm, 12 gauge and .50 Beowulf. Break Action, fed by moon clips, double-action revolver-style (internal) hammer which hits a selection of pins, which proceed to strike the back of each round.

There will be a tactilol version too.

It needs somewhere to attach a sling so that it can be fired from the hip.
