Radian Raptor-SD™ – Suppressor-Optimized Charging Handle
The Radian Raptor-SD™ is a top-tier charging handle designed specifically for suppressed AR-15 builds. Engineered with a ported shaft, it directs excess gas downward and forward, helping to reduce blowback to the shooter’s face—a critical upgrade for anyone running suppressed platforms.
Its fully ambidextrous design allows for smooth, intuitive manipulation from either side of the rifle, whether you’re reloading, performing clearing drills, or simply charging the weapon. Built from 7075-T6 aluminum and finished with a MIL-SPEC hardcoat anodize, the Raptor-SD is ready to handle real-world abuse in any environment.

Why We Recommend It
This is our go-to charging handle for suppressed builds. While no part completely eliminates gas blowback, the Raptor-SD noticeably improves comfort and usability during suppressed shooting. We’ve tested it extensively on a wide range of builds and consistently come back to it for its toughness, excellent fitment, and real-world performance under pressure.
Pro Build Tips
-
Dry Fit First: Run the charging handle back and forth in a stripped upper receiver before final installation to ensure fit and smooth travel.
-
Apply High-Temp Grease: Add a small dab of high-temp grease to the tabs that ride along the receiver walls, and in the U-shaped channel ahead of the handle. This smooths operation, catches carbon fouling, and reduces blowback over time.
-
Suppressor Users: Reapply grease periodically and wipe down after heavy use. These maintenance steps can significantly reduce eye-stinging gas and improve long-term reliability.
