Introducing The Donovan Manufacturing Ported Upper
A patent-pending upper receiver system designed to fix one of the AR’s biggest operational flaws: gas blowback to the shooter’s face.

- Health Focused: Reduces inhalation of carbon and carcinogens
- Suppressor Ready: Reduces suppressor blowback and preserves sight picture
- Bolt Speed Regulation: Improves shot consistency in select fire
- Drop-In Simplicity: Easy to license, manufacture, and implement at scale
Designed for OEM Integration
- No special tooling or process overhaul needed
- Minimal manufacturing change
- High-value performance gain for your end users
- Easy to co-brand, private-label, or integrate into your product line
