How Muzzle energy is calculated
E = ½ · m · v²
Inputs
- m3.43 g52.93 grverifiedsourceBallistics table of the cited article, which publishes bullet mass in grams.
- v880 m/s2,887 fpsverifiedMeasured with a 415 mm barrel, not this arm's 314 mm. Velocity outside the sourced range is not projected.

How Muzzle velocity is calculated
nearest sourced barrel length, no extrapolation
Inputs
- v at 415 mm880 m/s2,887 fpsverifiedsourceBallistics table of the cited article.
Assumptions
- This figure belongs to a 415 mm barrel. It is shown because it is the closest measurement that exists, not because it applies here.
1 of 1 inputs link to their source.
How Loaded mass is calculated
m_loaded = m_empty + m_magazine + n · m_cartridge
Not calculated: m_magazine has no sourced figure yet. Nothing is substituted for a missing input.
Assumptions
- One magazine, filled to the stated capacity. Spare magazines, optics, slings and lights are the owner’s, not the arm’s.
2 of 4 inputs link to their source.
How Free recoil is calculated
E_recoil = ½ · m_firearm · v_recoil²
Inputs
- m_firearm3.2 kg7.055 lbestimatedsourceWith empty magazine, from the infobox; no inline citation is given there.
- v_recoil0.9433 m/s3.095 fpsestimated
Assumptions
- Propellant gas momentum is excluded: ARMAG does not record charge weights. This is therefore a lower bound on the real free recoil, consistent between entries but smaller than a figure that includes the gas term.
- Free recoil: the arm is unrestrained. Stock design, muzzle devices, stance and shooter mass are not modelled, because none of them is a property of the arm.

How Capacity is calculated
as published for the primary chambering
Inputs
- capacity30estimatedsourcePublished as a 30-round detachable box magazine or 60-round casket magazine, from the infobox, uncited there; 30 rounds recorded here as the standard magazine.
1 of 1 inputs link to their source.
Derived figures
Computed from the sourced values above. Open ƒ on any figure for the formula, its inputs, and the assumptions it makes.
How Momentum is calculated
p = m · v
Inputs
- m3.43 g52.93 grverifiedsourceBallistics table of the cited article, which publishes bullet mass in grams.
- v880 m/s2,887 fpsverifiedMeasured with a 415 mm barrel, not this arm's 314 mm. Velocity outside the sourced range is not projected.

How Sectional density is calculated
SD = mass(gr) / (7000 · diameter(in)²)
Inputs
- mass3.43 g52.93 grverifiedsourceBallistics table of the cited article, which publishes bullet mass in grams.
- diameter5.6 mm0.2205 inverifiedsourceC.I.P. G1, maximum bullet diameter.
Assumptions
- Reported in the conventional lb/in² so it is directly comparable with published figures.
2 of 2 inputs link to their source.
How Power factor is calculated
PF = mass(gr) · velocity(fps) / 1000
Inputs
- mass3.43 g52.93 grverifiedsourceBallistics table of the cited article, which publishes bullet mass in grams.
- velocity880 m/s2,887 fpsverifiedMeasured with a 415 mm barrel, not this arm's 314 mm. Velocity outside the sourced range is not projected.
Assumptions
- A competition classification defined by the IPSC and USPSA rulebooks, stated in their units. It describes a scoring category, not an effect.
1 of 2 inputs link to their source.
How Magazine dump is calculated
t = (n − 1) / (rpm / 60)
Inputs
- n30estimatedsourcePublished as a 30-round detachable box magazine or 60-round casket magazine, from the infobox, uncited there; 30 rounds recorded here as the standard magazine.
- rpm600 rpmestimatedsourceFrom the infobox, uncited there.
Assumptions
- Cyclic rate held for the whole magazine, no stoppages, trigger held down. A theoretical figure for comparing mechanisms, not a measured one.
2 of 2 inputs link to their source.
How Sight error at 1 mm is calculated
θ = atan(misalignment / sight radius)
Not calculated: sight radius has no sourced figure yet. Nothing is substituted for a missing input.
Assumptions
- Shows what a stated aiming error costs. The misalignment is the reader’s figure; the site does not claim how well anyone aims.
No input on this calculation carries a clickable source yet.
Specifications
Every row here is generated from the schema, so a figure recorded on this entry cannot be missing from the table, and the same rows, read the same way, are what the comparison shows.

Scale
A to-scale outline against family siblings. The dimensions are sourced; the shape is a representative outline for the type, and says so.
- AK-105824 mm32.44 inheight not recorded
Representative outline: the dimensions are sourced, the shape is not. Overall length, and barrel length where recorded, are drawn from this entry's own figures; the profile is a generic one for the firearm type and says nothing about this arm's actual contours. AK-105 records no height, so its outline is drawn at the type's proportion. That height is part of the shape, not a measurement.
Detail
The AK-105 is a short-barreled carbine version of the AK-74M, designed by Mikhail Kalashnikov’s bureau in 1994 to replace the shorter AKS-74U, although both remain in service. It belongs to the AK-100 family of export- and domestically-oriented Kalashnikov rifles that Izhmash introduced in the 1990s, alongside the full-length AK-101 and AK-103 chambered in other cartridges.
Compared to the full-length AK-74M and AK-101/AK-103 rifles of the same family, the AK-105 keeps the same gas-operated, rotating-bolt action and 5.45×39mm chambering but cuts the barrel down to roughly half the length, trading effective range for a shorter, easier-to-handle weapon. It entered Russian military service in 2001 and has since been adopted domestically by the Russian Army in a role other AK-100-series rifles, sold mainly for export, generally do not fill, as well as by a number of other armed forces and law-enforcement services.
No figure on this page carries an inline citation in Wikipedia’s infobox, so mass, length, barrel length, cyclic rate and effective range are all recorded as estimated rather than verified, and no manufacturer specification sheet was reachable to improve on that. No published twist rate was found for this entry, and no photograph of the AK-105 with its stock folded appears on this site.
