The B&T Compact Reduced Back Pressure Quick-Attach .223/5.56mm Rifle 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. 

A quick attach/detach fastener system is used for compatibility with all flash hiders made to NATO A2 specifications, no need for a proprietary adapter.
