The Extreme Duty TriDelta design is ready for the most demanding magnum performance. This design reduces recoil, muzzle blast and concussion from the shooters position. The baffles are designed to efficiently capture the supersonic blast to reduce recoil while simultaneously directing noise and blast away from the shooters position. These are designed to work with any magnum rifle with proper and certified installation. The design allows for use up to and including the 0.338 Lapua caliber magnums without any modifications. The design can also be modified by a licensed gunsmith for larger threads and bore. Not for use on 50BMG firearms.
