Weight of a Kalashnikov assault rifle with a full magazine: from AK-47 to AK-12

The Kalashnikov assault rifle is a legendary weapon, known throughout the world for its reliability and simplicity. But when it comes to AK weight with full ammunition, many are faced with conflicting information. Some sources indicate the weight “by eye”, others confuse the models, and still others forget to take into account the weight of the cartridges. This article will help you understand the details: from standard AK-47 to modern modifications such as AK-12 or AK-15.

We analyzed technical data sheets, military standards and field data to provide accurate numbers. You'll learn how weight depends on caliber, barrel material, magazine type, and even what kind of cartridges are used - arr. 1943 or modern 7N6. Let’s also look at why soldiers often complain about the “heavy AK,” although according to the documents its weight seems acceptable.

Spoiler: the difference between an “empty” machine gun and an AK with a full magazine can reach 1.5 kg - It's like carrying an extra bottle of water. And that's not taking into account additional equipment!

Standard weight of AK-47: myths and reality

Classic AK-47 (index 6P1) weighs 4.3 kg without magazine and cartridges. This figure is recorded in the technical description and confirmed by repeated weighing of museum specimens. However, here are the nuances:

• 📦 Magazine weight (standard 30 rounds, steel): 330–350 g.
• 🔫 Weight 30 rounds 7.62×39 mm (sample 1943): 480–510 g.
• 🛠️ Weight of bayonet with sheath: 450–500 g (if attached).

Thus, total weight of AK-47 with loaded magazine amounts to 5.1–5.3 kg. But this is in a “naked” form - without a belt, case and additional accessories. In combat conditions, the following is often added to the machine gun:

• 🎒 Tactical belt (+200–300 g).
• 🔦 Flashlight or laser pointer (+150–400 g).
• 🎯 Optical or collimator sight (+300–600 g).

⚠️ Attention: AK-47 weight is often confused with weight AKM (modernized version). The latter is 0.5–0.7 kg lighter due to the lightweight barrel and plastic parts.

Comparison of the weight of different Kalashnikov models

Over the 70+ years of production, the Kalashnikov assault rifle has undergone many modifications. The main differences in weight are due to:

1. Caliber of cartridges (7.62 mm vs 5.45 mm vs 5.56 mm).
2. Material of the barrel and body (steel vs alloys vs polymers).
3. Type of magazine (steel vs plastic).

The table below compares the most common models in running order (with full magazine, without additional equipment):

Model	Caliber	Weight without magazine (kg)	Magazine weight (30 rounds)	Total weight (kg)
AK-47 (6P1)	7.62×39 mm	4,3	0,8–0,85	5,1–5,2
AKM (6P1M)	7.62×39 mm	3,6	0,75–0,8	4,4–4,5
AK-74 (6P20)	5.45×39 mm	3,3	0,6–0,65	3,9–4,0
AK-12	5.45×39 mm / 7.62×39 mm	3,2–3,3	0.55–0.6 (plastic)	3,8–3,9
AK-15	7.62×39 mm	3,8	0,7–0,75	4,5–4,6

Please note: AK-74 easier AK-47 almost 1.2 kg thanks to the smaller caliber and the use of plastic in the design. However cartridge weight also plays a role: 30 pieces of 5.45 mm weigh ~420 g, and 7.62 mm - ~500 g.

How does the weight of cartridges affect the overall mass?

Many people miss that ammunition weight May vary depending on ammo type. For example:

• 🔹 Ammo 7.62×39 mm arr. 1943 (with steel core): 16–17 g per piece.
• 🔹 Ammo 7N6 (5.45×39 mm): 10–11 g per piece.
• 🔹 Ammo 7N24 (7.62×39 mm, armor-piercing): up to 20 g per piece.

This means that the same AKM may weigh:

• 4.4 kg with conventional cartridges.
• 4.7 kg with armor-piercing.

In combat conditions, soldiers often take additional stores. For example, 3 magazines for an AK-74 will add another ~1.8 kg to the total weight of the equipment. And if you consider that in modern conflicts a fighter carries with him 6–8 stores, then only cartridges can weigh 3–4 kg!

⚠️ Attention: In mountainous or hot conditions, even 1 kg of excess weight increases fatigue by 15–20%. This is one of the reasons why special forces are often chosen shortened versions (AKS-74U, AK-105) despite the shorter firing range.

AK weight with additional equipment

Modern modifications of the Kalashnikov are rarely used "naked". They install:

• 🔦 Tactical flashlights (for example, SureFire M600): +200–400 g.
• 🎯 Sights (collimators EOTech or optical PO 3.5×21): +300–600 g.
• 🎤 Tactical Plugs/Muzzle Brakes: +100–250 g.
• 🔋 Laser pointers (for example, PEQ-15): +250–350 g.

As a result combat AK-12 with full equipment can weigh 5–6 kg - almost like the original AK-47, despite the lightweight design. At the same time center of gravity moves forward, which makes it more difficult to control the weapon dynamically.

For comparison: American M4 Carbine in a similar configuration it weighs ~3.8–4.2 kg, but uses cartridges 5.56x45mm NATO, which are lighter than Soviet/Russian ones.

Why do soldiers complain about the weight of the AK?

On paper, 4–5 kg does not seem like a critical load. However, in real conditions the weight is felt more strongly due to:

1. Long marches: Carrying a machine gun on a belt for 6–8 hours puts stress on the shoulders and back.
2. Uncomfortable center of gravity: On the AK it is shifted towards the muzzle, which requires constant effort to hold.
3. Additional equipment: Body armor, first aid kit, radio and water add 10–15 kg.

Interesting fact: in USSR tests were carried out where soldiers with AK-74 marched 25 km. It turned out that Weapon weight affects movement speed more than backpack weight - due to the need to constantly hold the machine gun in your hands.

How to reduce the load from AK?

Use two point belt instead of the standard one, it distributes the weight more evenly. Also helps shortened butt (for example, on the AKS-74U), but this reduces the accuracy of shooting at long distances.

How to weigh your AK at home

If you need to know the exact weight of your machine gun (for example, for historical reconstruction or collecting), follow the instructions:

1. Remove the magazine and check that the chamber is empty.
2. Use kitchen scales with a limit of up to 10 kg (error ±10 g).
3. Weigh the machine gun without a magazine, then weigh the magazine with cartridges separately.
4. Add the values to get the total weight.

For authentication AK-47 please note:

• 🔧 Markings on the receiver (must have factory marks and year of manufacture).
• 📏 Barrel thickness (the original AK-47 has 1.5 mm, the AKM has 1.3 mm).

⚠️ Attention: In Russia, civilian storage of a military AK is prohibited (Article 222 of the Criminal Code of the Russian Federation). You can only legally own deactivated or pneumatic copies (with muzzle energy up to 3 J).

FAQ: Frequently asked questions about AK weight

How much does an AK-47 weigh with a wooden stock and a steel magazine?

Exact weight - 5.1–5.3 kg with a full magazine (30 rounds of 7.62x39 mm). A wooden stock adds ~200g compared to a plastic stock, but this is offset by better ergonomics.

Why is the AK-74 lighter than the AK-47 if it is the same size?

Due to three factors: smaller caliber (5.45 mm vs 7.62 mm), lightweight barrel (thinner than the wall) and use of plastic in the store and butt. This reduced weight by 20–25%.

How much do 100 AK cartridges weigh?

Depends on caliber:

• 7.62x39 mm: ~1.6–1.7 kg.
• 5.45x39 mm: ~1.0–1.1 kg.
• 7.62×51 mm (for AK-103): ~2.2–2.4 kg.

In combat conditions, cartridges are often transferred to belts or unloading, not in stores.

Which AK is the lightest?

AK-12 in 5.45 mm caliber with a plastic store - total 3.3 kg without cartridges and ~3.8 kg with a full magazine. Even easier AK-105 (shortened version), but due to the shorter barrel length, accuracy is lost at distances over 300 m.

Is it possible to reduce the weight of an AK without losing reliability?

Yes, but with reservations:

• 🔄 Replace the steel magazine with plastic (saving ~100 g).
• 🔨 Shorten the barrel (as in the AKS-74U), but this will require re-registration of the weapon.
• 🛡️ Use composite stock (saving ~150 g).

However, any modifications may affect weapon resource and accuracy of fire.
