A Magnifier is an optical attachment used with Red Dot Sights and Holographic sights. Magnifiers provide users of these non-magnifying sights with improved target recognition at medium and long ranges, while still allowing the shooter to make use of their sight for shorter ranges.
The Magnifier is a weapon attachment featured in Battlefield 4. It offers a toggleable 2x magnification to any 1x sight (any in the "close range" category), such as a Red Dot Sight or a Holographic Sight.
It serves as the counterpart to the Canted Ironsights attachment -- a shortstop between a medium-range sight and a close-range sight which offers greater zoom in exchange for a more obfuscated field of view. It is not available for the PDWs, and is replaced by Variable Zoom on sniper rifles. It is also the default accessory attachment for the U-100 MK5.
The Magnifier can be toggled on or off by selecting the key mapped to. The default key is T on the PC or D-Pad Up on consoles. A short animation of the player's soldier moving the magnifier into place will play when the Magnifier is toggled on or off; the player is still able to fire his weapon during the animation, but will be unable to aim down sight until the animation is complete.
A Magnifier (2x) appears as an accessory in Battlefield Hardline.
- When toggled on, the Magnifier doubles the zoom factor of an underslung M320 or GP-30, even though the player does not look through the magnifier.
- The Magnifier is represented by a magnifying glass on the inventory bar.
- A bug may occur in which toggling the magnifier on will not change anything, but toggling it off will render the zoom. This goes away upon respawn.
- The Magnifier featured in Battlefield 4 is modeled after the EOTech G33 Magnifier.
