The JMAC 360HD X37 HUB Muzzle Brake in 1/2×28 facemount (JMAC part no. 360HD-28F-X37) is a recoil reduction device with a direct-thread HUB 1.375-24 suppressor interface. This 1/2×28 version is a facemount made for AR-15, 9mm PCC and AKV hosts, and JMAC notes face milling is required. Because the suppressor threads straight on, it skips the QD system and extra adapters, which saves weight, length and cost. It is made from 17-4 PH stainless steel with three sacrificial baffles ahead of the suppressor, and JMAC lists it as needing no timing and having no barrel length restriction.
