Insurgency Wiki

A heavy barrel is usually a thicker and heavier barrel that is designed for use on marksman rifles and machine guns. Because the barrel has more weight, it reduces the felt recoil and muzzle climb of a firearm.


In Insurgency, the heavy barrel is a barrel attachment available for the Security Forces. It is able to reduce the vertical recoil of a weapon by essentially increasing the weight of the front, thus counteracting some recoil forces. However, equipping the heavy barrel will also increase the player's loadout weight. The heavy barrel's in-game description is misleading, as it has no affect on a weapon's spread.


  • 10% reduction in vertical recoil
  • 60% reduction in sway speed

Compared to the bipod and foregrip, the heavy barrel is (usually) the cheapest option of the three accuracy-improving attachments. The heavy barrel is also a barrel attachment, meaning that it can be paired with either the bipod, or the foregrip, leading to a very accurate weapon overall.

The heavy barrel and bipod together can be a cheaper alternative to the single foregrip, interestingly. The bipod is either free, or worth one supply point in this case, and the heavy barrel is always worth one supply point.

There is no method of having the bipod, foregrip, and heavy barrel on one gun, but the heavy barrel is compatible with either attachment. For builds focused entirely on accuracy, either pair of these attachments work well.


  • When compared to the foregrip, the heavy barrel is more effective at reducing weapon sway. This makes it more suited for a marksman role.
  • The heavy barrel is good on fast-firing, high-recoil weapons like the Mk 18, especially given how cheap the attachment is.
