B&T MP5 SD 9mm RBS Modular Suppressor SD-MP5SD-RBS-M

The B&T MP5 SD RBS Modular Suppressor (model SD‑MP5SD‑RBS‑M) is a fully titanium, modular suppressor designed specifically for integrally suppressed MP5 SD platforms—also compatible with early-generation APC9 SD submachine guns. The Print‑X design offers exceptional reduction in weight while maintaining military-grade durability. At its core is a low-pressure expansion chamber that significantly dampens sound and flash, while minimizing gas blowback for a smoother shooting experience. Customizable to up to six unique configurations by mixing three modular sections with vented or sealed endcaps.

Key Features:

• Material: 3D‑printed, weld‑free titanium construction for lightweight ruggedness
• Modular Design: Three removable sections enabling subcompact (≈7.9 in), compact (≈10.8 in), or full‑length (≈13.7 in) setups
• RBS Toggle: Vented endcap for Reduced Back‑Pressure System (RBS) to decrease gas pressure, or sealed cap for maximal suppression
• Configurations: Six total combinations (three section lengths × two endcaps)
• Caliber: 9 mm—optimized for MP5 SD and APC9 SD platforms
• Weight: Between approximately 8 oz (227 g) and 17.1 oz (482 g), depending on configuration
• Length Options: ~7.9", 10.8", or 13.7" combined suppressor length
• Diameter: ~1.5 in (40 mm)
• Attachment: Direct-connect design engineered for standard MP5 SD barrel interfaces; full‑auto rated

Designed as a direct drop-in replacement for MP5 SD factory suppressors, the SD‑MP5SD‑RBS‑M balances modular flexibility, low signature performance, and ergonomic handling. Built for mission adaptability—whether you need minimal length and weight or maximum noise reduction. Proudly manufactured by B&T under their Print‑X titanium program.
