BDS-37 JMac Customs

JMac Customs BDS-37 or Blast Diversion Shield-37(1.375-24 threads) was co-developed with the JMac Customs RRD-2C X series of muzzle brakes with external threads. This blast shield threads over JMac Customs RRD-2C X and diverts the blast forward, reducing side blast/concussion all while giving a finished appearance. 

In addition to threading over the RRD-2C X, the BDS can also be used with a wide range of suppressor adapters/mounts, see below.
