## Notes

* Mods that increase or decrease weight are all percentage-based reductions. Depending upon the exact mod and weapon, some mods are close to the stated benefits/penalties, some are slightly lower or higher, and a few are not even close to the stated value. *For a detailed investigation of weapon weight mechanics, see Weapon Weight Strategy.*
* The multiplayer AR Barrel and AR Magazine can be purchased with the DLC Asari Adept Multiplayer Recruit Pack and Turian Soldier Multiplayer Recruit Pack.
* The multiplayer stats shown are accurate as of Multiplayer Update - November 7, 2018.
* Equipped items have a green check mark .
* Accuracy is a different weapon property than stability. The accuracy of a weapon will change the size of the aiming reticle. Stability reduces the kickback and rise of the weapon during firing.

† The AR Targeting System is only available in multiplayer.
