The Kalashnikov assault rifle is a legendary weapon, known throughout the world for its reliability and simplicity. But when it comes to its weight, many are faced with confusion: the numbers in the technical specifications often indicate the mass empty machine gun, whereas in battle weight is important equipped weapons - with a magazine, cartridges and additional equipment. The difference can reach 1.5–2 kg, which is critical for long marches or dynamic operations.

In this article we will figure out how much the most common AK modifications actually weigh - from the classic AK-47 to modern AK-12 - in different configurations. You will learn how the equipment (flash suppressor, sight, under-barrel grenade launcher) affects the overall weight, and why even “light” options can seem heavier in battle. And for those who are planning a purchase or upgrade, we have prepared a comparison table and practical tips for reducing the load.

Why AK weight is more important than it seems

On paper, the difference between 3.5 kg and 4.8 kg may seem negligible. But in real conditions:

  • 🔹 Marching load: during a 20-kilometer trek, each extra kilogram increases fatigue by 10–15%. The weight of the machine gun + ammunition (6–8 magazines) may exceed 10 kg.
  • 🔹 Maneuverability: In urban battles or wooded areas, heavy weapons slow down the shooter's reaction by 0.3–0.5 seconds when moving between covers.
  • 🔹 Firing accuracy: studies show that a shooter with a weapon weighing >4.5 kg loses up to 20% of accuracy when shooting for a long time while standing.

I wonder what AK-12, marketed as "ergonomic", weighs almost as much as AK-74M - the difference is only 200 grams. But the weight distribution of the modern model is optimized for handholding thanks to a shifted center of gravity.

📊 What weight of the machine is critical for you?
Up to 4 kg - light option
4–4.5 kg – optimal
4.5–5 kg – acceptable
More than 5 kg - not important

Empty weight vs. equipped machine gun: what's the catch

Manufacturers and reference books usually indicate weight of the machine gun without magazine and cartridges. For example, for AK-74M this is 3.4 kg. But in battle, weapons are used with:

  • 🔫 Store: a standard plastic one with 30 rounds weighs ~250 g, a metal one weighs up to 400 g.
  • 💥 Ammo: 30 rounds of 5.45x39 mm caliber add ~450 g, 7.62x39 mm - up to 600 g.
  • 🎯 Additional equipment: collimator sight (+200–300 g), tactical handle (+150 g), flashlight (+100–200 g).

Thus, AK-74M in the “combat” configuration it already weighs 4.5–5 kg. And if you add an underbarrel grenade launcher GP-25 (+1.3 kg), the weight will approach 6 kg!

⚠️ Attention: The weight of a loaded assault rifle may exceed NATO ergonomic standards (maximum 3.6 kg for assault weapons). This is one reason why soldiers often remove unnecessary accessories during long operations.
Model Weight without magazine (g) Weight with empty magazine (g) Weight with loaded magazine (30 rounds) Weight with GP-25 and 30 rounds
AK-47 (tree) 4 300 4 550 5 100 6 400
AKM 3 140 3 390 3 940 5 240
AK-74 3 300 3 550 4 000 5 300
AK-74M 3 400 3 650 4 100 5 400
AK-12 3 300 3 550 4 000 5 300

How equipment affects weight: from the stock to the grenade launcher

Even within the same model, weight can vary by ±500 g depending on components. Let's look at the key factors:

1. Receiver and stock material

  • 🌲 Wood (AK-47, early AKM): 300–400 g heavier, but more reliable in extreme conditions.
  • 🖤 Plastic (AK-74M, AK-12): lighter, but less resistant to mechanical damage.
  • 🛡️ Carbon fiber (upgraded versions): reduces weight by 150–200 g, but increases cost by 2–3 times.

2. Store type

Metal magazines (for example, from AK-47) weigh 150 g more than plastic ones, but are less susceptible to deformation when dropped. 75-round drum magazine (same as PKK) adds 1.2 kg even empty!

3. Additional equipment

Modern "tactical" accessories can double the weight of a weapon:

  • 🔦 Tactical Flashlight: +100–200 g (for example, SureFire X300 - 180 g).
  • 🎯 Sights: collimator EOTech — +300 g, optical PO 4×24 — +500 g.
  • 💣 Underbarrel grenade launcher: GP-25 — +1.3 kg, GP-34 — +1.5 kg.
  • 🔇 Muffler: +400–600 g (for example, PBS-4 for 7.62 mm).

Remove unnecessary accessories (laser pointer, additional handles)

Replace a metal magazine with a plastic one

Use a lightweight stock (for example, a folding stock from an AK-12)

Remove the grenade launcher if you do not plan to use it

Choose a compact sight (for example, micro-reflex instead of optics) -->

Comparison of AK weight with foreign analogues

For the sake of objectivity, let’s compare Kalashnikovs with popular foreign assault rifles. Please note: foreign manufacturers often indicate weight with an empty magazine, while in Russian sources the mass appears more often without store.

Model Country Weight without magazine (g) Weight with loaded magazine (30 rounds) Caliber
AK-74M Russia 3 400 4 100 5.45×39 mm
M16A4 USA 3 400 3 900 5.56×45 mm
HK G36 Germany 3 300 3 800 5.56×45 mm
FAMAS F1 France 3 600 4 100 5.56×45 mm
Steyr AUG Austria 3 200 3 700 5.56×45 mm

As can be seen from the table, AK-74M It is not the heaviest in the class, but it is not a light rifle either. The main difference is weight distribution: in the Kalashnikov, the center of gravity is shifted closer to the receiver, which makes it easier to hold during automatic shooting, but tires the hand when carrying it for a long time.

💡

If you need to make your AK as light as possible for marching, consider one with a folding stock and a plastic magazine. For example, AKS-74U weighs only 2.7 kg without cartridges, but has a shortened barrel, which reduces accuracy at distances over 200 m.

Cartridge weight: why 5.45 mm is more profitable than 7.62 mm

Caliber directly affects the total weight of the ammunition. Let's compare the two most common AK cartridges:

  • 🔘 7.62×39 mm (AK-47/AKM):
    • Cartridge weight: ~16 g.
    • Weight of 30 rounds: ~480 g.
    • Weight 210 rounds (7 magazines): ~3.4 kg.
  • 🔘 5.45x39 mm (AK-74/AK-12):
    • Cartridge weight: ~10.5 g.
    • Weight 30 rounds: ~315 g.
    • Weight 210 rounds: ~2.2 kg.

The difference of 1.2 kg with a full load (7 magazines) may seem insignificant, but in mountainous areas or hot climates it affects the shooter’s endurance. That's why AK-74 and its modifications have become standard weapons in the Soviet and Russian militaries since 1974.

⚠️ Attention: 5.45x39mm cartridges have less stopping power compared to 7.62x39mm. In close combat (up to 100 m) this can be critical - more accurate shooting at vital organs is required.

How to reduce the weight of a machine without losing functionality

If you need to lighten your weapon for long operations, follow these guidelines:

  1. Replace metal parts with polymer ones:
    • Stock: saving up to 300 g (for example, stock from AK-12 instead of wooden).
    • Forend: plastic instead of wood - minus 200 g.
    • Magazines: plastic instead of steel - minus 150 g per magazine.
  2. Optimize your ammunition load:
    • Use 20 round magazines instead of 30 rounds (saving ~150g per magazine).
    • Carry ammo in pouches on your belt rather than in your backpack - this distributes the load.
  3. Remove unnecessary accessories:
    • Bayonet: ~300 g (used extremely rarely in modern battles).
    • Strap: ~200 g (if you do not plan to carry it on your shoulder).
    • Additional handles: ~150 g each.
  • Select a light scope:
    • Replace 4× optics with a collimator (saving ~200 g).
    • Use micro-reflexes (eg. Holosun HS510C - only 120 g).

      • Example: if you take AK-74M with a plastic butt, 20-round magazines and a collimator, its weight will drop from 4.1 kg to 3.5 kg - it's on par M16A4!

      The myth of the “weightless” AK-12

      The designers of the AK-12 claimed a 20% weight reduction compared to the AK-74M, but in reality the difference was only 100–150 g. The main improvement is ergonomics, not weight. Reason: use of more durable materials for the receiver (to withstand the increased pressure of the new 5.45x39 mm cartridges).

      FAQ: Frequently asked questions about the weight of the Kalashnikov assault rifle

      How much does an AK-47 weigh with full ammunition (8 magazines of 30 rounds each)?

      Weight itself AK-47 with a wooden butt - 4.3 kg. Weight of 8 loaded magazines (7.62 × 39 mm): 8 × (250 g + 600 g) = 6.8 kg. Total: 11.1 kg. For comparison: this is the weight of an average watermelon or two laptops.

      Why didn't the AK-12 become lighter than the AK-74M?

      Main reasons:

      1. Reinforced receiver for new 5.45x39mm cartridges (high pressure).
      2. A unified platform for different calibers (5.45 mm, 5.56 mm, 7.62 mm), which required a more massive design.
      3. Additional guides for accessories (type Picatinny), which increased the weight by ~100 g.

    But ergonomics and accuracy of fire have improved by 30–40%.

    Which Kalashnikov assault rifle is the lightest?

    The lightest production model - AKS-74U ("shortened"):

    • Weight without magazine: 2.7 kg.
    • Weight with loaded magazine (30 rounds of 5.45x39 mm): 3.2 kg.

    However, it has a short barrel (200 mm), which reduces the muzzle velocity and accuracy at distances over 200 m.

    Does the weight of a machine gun affect recoil?

    Yes, but not as much as the caliber and bolt design. Heavy weapons (eg. AK-47) better absorbs recoil due to its mass, but tires the shooter during prolonged shooting. Lightweight models (such as AK-12) have a sharper recoil, but return to position for the next shot faster.

    To reduce recoil it is more important:

    • Muzzle brake-compensator (saves up to 30% recoil energy).
    • Buffer springs in the butt (reduce the “blow” to the shoulder).
    • Correct shooting technique (tight fit of the butt to the shoulder).
    Is it possible to reduce the weight of an AK by cutting off parts of the barrel or butt?

    Absolutely not! This breaks:

    • 📜 Law: In most countries, unauthorized modification of firearms is prosecuted under the article “Illegal carrying/storage of weapons.”
    • 🔧 Security: sawing down the barrel changes the balance, increases recoil and can cause the case to rupture.
    • 🎯 Accuracy: a shortened barrel reduces the initial velocity of the bullet by 15–20%, which worsens accuracy at distances over 100 m.

      • Legal ways to lighten a weapon: replacing the stock, forearm and magazines with polymer ones, removing unnecessary accessories.

    💡

    The weight of a loaded Kalashnikov assault rifle varies from 3.2 kg (AKS-74U) up to 6.5 kg (AK-47 with GP-25). Optimal balance of weight and functionality - AK-74M or AK-12 with a plastic stock and 20-round magazines (total weight ~3.8–4 kg).
