What’s Included in the AP5-SD K Conversion?

Every Ronin Arms AP5-SD K conversion is built using premium-grade components for superior performance and longevity:

🔹 8” Defcon4 SD Suppressor

The heart of this conversion—our integrally suppressed system delivers industry-leading sound reduction, minimal first-round pop, and seamless integration for a whisper-quiet shooting experience.

🔹 5.75” Ronin Arms Ported SD Barrel
Engineered for perfect gas regulation, this precision-machined, ported barrel ensures optimal subsonic performance—especially with 115gr and 124gr ammo. Barrel is professionally installed and head-spaced for reliable, accurate operation.

🔹 SD Cocking Tube & Cocking Tube Support

Designed for smooth cycling and enhanced reliability, this upgrade ensures flawless operation in suppressed setups.

🔹 120° SD Locking Piece

The AP5SD comes with a 120° locking piece, perfect for the SD system. It helps reduce recoil, improve cycling, and keeps your setup running smoothly.

🔹 High-Temperature Sealing Ring

Seals gas flow for maximum efficiency, reducing carbon buildup while improving overall suppressor longevity.

🔹 Reinforced for Strength & Longevity

Reinforcement welds are added to the rear of the barrel shroud to ensure durability and long-term reliability. We saw the unsupported barrel shroud as a weakness in the platform—and we fixed it.

✅ Includes: Defcon4 Suppressor, all required SD components, and expert installation.
