Insurgency Wiki

The AC556 is a lightweight select-fire 5.56×45mm carbine manufactured by the U.S. firearms company Sturm, Ruger & Co., Inc. Introduced in 1973, It is military version of the popular Mini-14 semi-automatic rifle series also made by Sturm, Ruger & Co., and was marketed as a cheaper alternative to the popular M16. In the end, the firearm did not see substantial success, and was subsequently dropped all together in 1999.


The AC-556 is a carbine featured in Insurgency. It is exclusive to the Security Forces. It has a 20 round magazine, moderate recoil, and may fire in semi-automatic, 3-round burst, or fully automatic. In comparison to other carbines and assault rifles, it is lacking in terms of magazine capacity, but it makes up for its ammo shortcomings with unobstructive iron sights, 3 types of firing modes, and a lower supply cost than other automatic carbines on the security faction.



CO-OP only:



  • The first person model depicts the 13" barrel AC-556 while the third person model depicts the 18" barrel Mini-14. 
  • In real life, 30-round and 20-round magazines were created for the AC-556. However, the version in game only uses a 20-round magazine for balance. 
  • In previous versions of Insurgency, the AC-556 was actually called the Mini-14, and was subsequently limited to semi-automatic fire.
  • During the alpha stages of Insurgency, the AC-556 was incorrectly referred to as a full size M14.
