The device protrudes past the end of the barrel 7.5 inches and goes back over the barrel to a point in front of the gas block. A barrel fitting that attaches to the barrel near the gas block assembly is used in conjunction with the threaded muzzle to align and secure the device to the weapon. Once the barrel fitting is installed no tools are required to remove or install the MBS to the weapon. The 28 oz weight of the device is offset due to the flash hider being removed from the weapon.
Note: This suppressor was tested by Crane on an HK21, by firing 1400 rounds in 15 minutes with no degradation in performance. Machine gun suppressor pricing is based on customer providing the applicable weapon and 100 rounds of linked ammo per suppressor for testing of each unit before shipment.
