The Ak 5 (sometimes AK5) is the Swedish version of the FN FNC assault rifle with certain modifications, mostly to better adapt the weapon to the Swedish climate. The Ak 5 is the standard weapon of the Swedish Army. Ak 5 is an abbreviation of automatkarbin 5 (in English automatic carbine 5). The rifle is also known as the CGA5 meaning Carl Gustav Automatic carbine 5.

There are several specialized versions available: the Ak 5B with a telescopic sight and a shortened version, the Ak 5D. A modified version of the Colt M203 grenade launcher can also be attached to the Ak 5. This setup is simply designated Ak 5 med granattillsats meaning "Ak 5 with grenade [launcher] attachment".

Ak 5B

Ak 5B is a version of the Ak 5 that is mounted with a SUSAT L9A1 tritium sight.

Specifications

• Weight (no clip): 4.8 kg
• Weight (full clip): 5.4 kg

Ak 5C/Ak 5CF

The Ak 5C is an updated version of the original Ak 5. It has no open sights, but is instead mounted with the MIL-STD-1913 rail system on to which a wealth of different sights can be mounted, for example the SUSAT. The Ak 5C will most likely be the new standard weapon of the Swedish Army, together with the Ak 5D.

Before the Ak 5C goes in to mass production it is to be thoroughly evaluated. This is done by letting certain units try an experimental model called the Ak 5CF where F stands for the Swedish word försök (meaning, in this context, experiment/trial). These are the new features of the Ak 5CF compared to the original Ak 5:

• Black
• Slidable and foldable butt
• New pistol-grip (similar to the one on Ksp 90 )
• Last-shot bolt hold-open
• Plastic magazines
• The MIL-STD-1913 rail system
• New forward grip (more stabile)
• Vertical forward grip (detachable)
• Only one gas mode
• New flash damper
• Bayonet socket
• Improved probability of functioning
• Tactical strap

Contrary to popular belief, the Ak 5 mounted with the Colt M203 grenade launcher is not called the Ak 5C.

Ak 5D

The latest modification of the Ak 5 is designated Ak 5D and most notably has a shorter barrel. Just as the Ak 5C it is mounted with the MIL-STD 1913 rail system to allow for easy mounting of a variety of sights.

Due to the smaller dimensions of the weapon, the Ak 5D is used especially by personnel in crowded spaces such as the Swedish urban warfare units and on certain marine units. The Swedish police are also equipped with a version of the Ak 5D, see below.

CGA5C2

The CGA5C2 (Carl Gustav Automatic Carbine 5 C2) was a prototype model during the development of the replacements/modifications to the original Ak 5 described in this article.

CGA5P

The Swedish police are equipped with a special version of the Ak 5D called CGA5P or sometimes, incorrectly, Ak 5DP. Essentially it is a black Ak 5D (instead of the regular military green) with the automatic mode blocked with an Allen key. Unlike the Ak 5D, the police version has fixed sights but is still equipped with the MIL-STD 1913 rail system. Eventually, telescopic sights or red dot sights will be used. Unlike its military counterparts, the police version also has safety catches on both sides of the weapon.
