Modern Warfare 4 Gunsmith Adds Optic Rail Placement
Infinity Ward says the new Optic Rail Placement setting lets players slide an equipped optic along the top rail and is entirely cosmetic.
Call of Duty: Modern Warfare 4 includes a new Gunsmith feature called Optic Rail Placement, which lets players move an equipped optic forward or backward along the weapon's top Picatinny rail from the Gunsmith interface, according to Game Rant. Infinity Ward describes the setting as entirely cosmetic and says it does not affect weapon stats.
Players can preview optic position changes from the ADS perspective while adjusting the slider, so the shift in sight picture is visible before leaving the menu.
A Gunny assistant and cosmetic-only tuning
Modern Warfare 4's Gunsmith also includes a Gunny assistant that assembles weapon configurations around different engagement ranges. Infinity Ward's cosmetic-only framing means Optic Rail Placement sits apart from stat-changing attachments, with the slider presented as a visual preference rather than a performance choice.
The feature follows earlier experiments with optic positioning in the series. In 2022, the Call of Duty: Modern Warfare 2 reboot's Weapon Tuning system let players adjust an Eye Position slider on compatible optics once a weapon reached its maximum level.
Call of Duty: Modern Warfare 4 was released on October 23, 2026, by Infinity Ward and Activision.
