Ptr 9 SD-B SD SBR

• The PTR 9SDM-B is a factory-configured, semi-automatic 9×19mm short-barreled rifle that integrates a collapsible stock and suppressor into a single, cohesive system. Sold as an SBR with the PTR CS1 collapsible stock and the new Vent™ SDM suppressor installed, it delivers a compact MP5-pattern platform optimized for suppressed operation from the start.
• Built around a 6” barrel and a continuous extended top rail, the 9SDM-B emphasizes system-level suppression, optic flexibility, and accessory density. It represents the next-generation suppressed SBR configuration within the PTR lineup, designed for users who require a modern, fully integrated suppressed solution with minimal compromise.
• The PTR® 9SDM B combines modern innovation with iconic style. This integrally suppressed variant of the PTR 9CT is engineered for exceptionally quiet performance without sacrificing reliability or handling. The 9SDM B combines the proven roller-delayed blowback system with a purpose-built suppressor and ported barrel, creating a compact platform optimized for peak sound suppression and control.

The innovative design of the 9SDM features specially engineered slots in the barrel’s rifling grooves to port off gas, reducing supersonic bullet velocity to subsonic. This design also prevents bullet-jacket damage, minimizes fouling, and allows far easier cleaning than traditional SD firearms. The ported gas flows into the 9SDM’s pre-suppressor, which PTR calls the USDA (Universal SD Adapter). The USDA is designed to capture and slow high-pressure ported gas before it enters the suppressor. For increased modularity, the USDA is threaded to accept both HUB Alpha and HUB Bravo suppressor thread patterns.

The 9SDM-B will include the new purpose-built PTR VENT™ SDM suppressor (threaded HUB-B 1.375-24). The VENT SDM suppressor was designed specifically for ultimate sound suppression when paired with the 9SDM. The VENT SDM and is manufactured using 3D-printed titanium, utilize innovative Purposely Induced Porosity™ (PIP) technology, and are protected by a DLC coating. The VENT SDM excel at reducing sound signature and back pressure while preserving the balance and smooth recoil of the 9SDM.

• The platform also features a full-length Picatinny rail, Removable M-Lok® forend, metal MagPul® backup sights, and an extended charging handle (threaded to accept most Remington 700 pattern bolt knobs). The 9SDM represents the next evolution of the SD platform, engineered for shooters who demand the highest level of performance without compromise.
