The BPR2 by MadBull is a replica Back Pressure Regulator with licensed OSS trademarks. This mock suppressor features a unique octagonal design, and has deep engraved trademarks and markings. The MadBull version has recessed threads, and covers 2 3/8 inch of the barrel when installed.
OSS designed their suppressors to eliminate back-pressure and over-gassing common with other rifle silencers. This suppressor design was officially selected by HK for use on their G28 DMR, based on the HK417.
