- "A modified barrel that drastically increases headshot damage and converts the weapon to semi-automatic fire."
- — Gunsmith Description
The CHF Semi-Auto Conversion is a Barrel attachment featured in Call of Duty: Black Ops 6. It was added alongside the Season Six update as an exclusive attachment for the Merrick 556 Assault Rifle.
The attachment functions as a replacement for the CHF Barrel and while it does give the same upsides and downsides, it does so with a drastic uptick of those with the added benefit of converting the weapon into a semi-automatic form at base. However, the weapon loses additional handling functions with that.
