MP5 SD Suppressor

The all-new MP5SD RBS suppressor is an updated design and direct replacement for legacy Heckler & Koch (HK) MP5SD models. This over the barrel suppressor has been updated with our Reduced Backpressure System technology — significantly reducing the combustion gases escaping from the ejection window — venting excess gas at the muzzle end of the suppressor and away from the shooter. A low-pressure expansion chamber minimally increases the size and weight of the unit compared to conventional baffled models, all while providing industry-leading sound and flash signature reduction and a near gas-free shooting experience.
