Donovan Manufacturing LLC

The AR platform has evolved in optics, rails, suppressors, and materials.
Gas management has lagged behind.

The patent-pending Donovan Manufacturing Ported Upper addresses that gap directly. By venting gas forward and away from the shooter during recoil, it mitigates gas blowback, improves recoil management, and reduces felt recoil — suppressed or unsuppressed.

For operators and armed professionals, that means:
• Cleaner sight picture during rapid engagement
• Less back pressure in suppressed configurations
• More consistent recoil behavior
• Reduced exposure to excess gas at the face and head

Managing pressure at the upper receiver level changes how the entire system feels and performs.

For manufacturers, this isn’t a niche feature. It’s a licensing-ready, easily integrated enhancement that adds measurable performance value without disrupting production. Minimal additional tooling. No redesign of the operating system. Scalable across product lines.

The future of the platform isn’t just lighter or faster.
It’s smarter gas control.

Professionals deserve it.
The industry should adopt it.

Patent pending. Licensing open.

When the call comes in, your rifle can’t introduce new problems.

The TRDT, built around the patent-pending Donovan Manufacturing Ported Upper, vents gas forward and away from the shooter — reducing blowback to the face, improving recoil management, and mitigating felt recoil with or without a suppressor.

For law enforcement, that means:
• Clearer sight picture in high-stress encounters
• More predictable recoil for faster follow-ups
• Less back pressure on suppressed duty rifles
• Consistent performance across the stack

When pressure is managed at the source, officers stay focused on the threat — not fighting their equipment.
