Factory original B&T RBS Reduced Back Pressure sound suppressor that is compatible with weapons such as the MP5, APC9 and others utilizing HK's famous 3-lug barrel. Thanks to it's 3-lug lock it can be mounted/dismounted on all weapons with MP5/APC9 type 3-lug on the barrel in a matter of seconds, even faster than the normal QD suppressor. To mount the suppressor it must be slid on the barrel, where it locks automatically in place thank to the innovative SQD mount. To release the suppressor, only one knob has to be pressed in order to dismount the suppressor.The B&T RBS Reduced Back Pressure Quick-Attach 9mm Sound Suppressor does exactly what it's name implies while still offering the performance and sound reduction that B&T sound suppressors are known for. There are many advantages in using suppressors, the back flow of the retained gases from the ejection port and charging handle is a disadvantage. The gas blowback in the face of the operator is not only a nuisance but also a health risk, especially indoors. B&T addresses this issue with the RBS (reduced back pressure suppressor).The low-pressure chamber design is able to absorb a significant amount of gas, drastically reducing the back pressure, making the RBS a great choice for semi-auto rifles and machine guns. While traditional suppressors will increase the cyclic rate by up to more than 30% due to back pressure, B&T RBS's unique design increases the cyclic rate by only 4%, which ultimately reduces both fouling and wear and tear on the gun.
