556 Direct Thread Hyflow Gen5

The 556 DTHF Gen 5 is the latest iteration of the Hyflow design and a substantial improvement in size, flash and sound signature. This suppressor is a small, robust, direct thread rifle suppressor made from 718 inconel or titanium 6-4 powder using Selective Laser Melting or 3D metal printing technology. The design is optimized for semi auto and select fire rifles to provide the best user experience in terms of noise reduction and low gas back pressure. The 556DTHF is safe to use for 556 bolt action rifles, however single flow suppressors will provide a better solution in bolt action rifles and are available in either direct thread and QD from ODL for most calibres.

The Hyflow uses a patented flow design where gas is split into two paths at the blast baffle. The central path uses a very aggressive baffle design with room for the bullet to pass and an outer flow path where half the gasses are allowed to flow in a semi impeded path out separate holes around the periphery of the conical suppressor bore. The flow is balanced so that both paths exit at about the same time resulting in maximum suppression in minimum time for reduced impact to the firearm operational design, while maintaining reasonable sound reduction at both the muzzle and shooter’s ear.

Due to the parallel processing of the Hyflow, gas is processed twice as fast as a single flow suppressor. The result is nearly identical bolt velocity and back pressure in suppressed direct impingement systems as an unsuppressed rifle. Faster gas processing allows time for suppressor pressure to drop before the bolt opens allowing gas to exit out the front of the suppressor instead of venting back at the user.

The 556 DTHF is a one-piece design for maximum strength to weight ratio and cannot be disassembled. It mounts muzzle forward, indexing on the barrel shoulder to minimize any impact on laser or light placement.
