Battlefield 4 Ergo grip
Battlefield 4 Ergo grip can be applied to most weapons in the game.

Battlefield 4 Ergo grip info
The Battlefield 4 Ergo grip, short for ergonomical grip, looks slightly different than the vertical grip. They both reduce the accuracy penalty when the player is on the move and firing his weapon. However, this doesn’t mean that the accuracy will be the same as when the player is standing. The Ergo grip increases accuracy only slightly.
