The '''Ak 5''' (sometimes ''AK5'') is the [[Sweden|Swedish]] version of the [[FN FNC]] [[assault rifle]] with certain modifications, mostly to 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".
==1929==
 
==Ak 5B==
The first mass-produced GM straight-6 was introduced in [[1929]] on [[Chevrolet]] cars and trucks. It was 194&nbsp;in&sup3; in size and produced 50&nbsp;hp.
'''Ak 5B''' is a version of the Ak 5 that is mounted with a [[SUSAT]] L9A1 tritium [[telescopic sight|sight]].
==1937==
 
===Specifications===
The first-generation Chevrolet straight-6 was introduced in [[1937]] and phased out in [[1953]]. Both 216&nbsp;in&sup3; and 235&nbsp;in&sup3; versions were produced. This generation did not use pressurized oiling.
*Weight (no clip): 4.8 kg
*Weight (full clip): 5.4 kg
 
==1953Ak 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:
The early straight-6 was replaced by a pressure-oiled 235&nbsp;in&sup3; in [[1953]]. A 261&nbsp;in&sup3; version was also produced.

*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]]

Contrary to popular belief, the Ak 5 mounted with the [[Colt]] [[M203]] grenade launcher is ''not'' called the Ak 5C.
The '''230''' displaced 230 cubic inches (3.8L).
 
==Ak 5D==
This engine was used on the following vehicles:

* 1967 [[Chevrolet Camaro]]
The latest modification of the Ak 5 is designated '''Ak 5D''' and most notably has a shorter [[Barrel (firearms)|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.
==3.8==
 
==CGA5C2==
The Pontiac '''3.8''' was a special [[SOHC]] version of the standard 230 (3.8L) I6. An optional '''W53''' version on the Firebird produced 215hp.
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==
This engine was used on the following vehicles:
The Swedish and Norwegian 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|Allen screw]]. 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
