Schultz & Larsen mini-dampers are produced for the smallest caliber. The 17 HMR damper uses a part of the technology from the larger hunting dampers. The silencer is modular and can be expanded with several modules. 17 The HMR damper is supplied as standard with 9 modules but can be expanded with up to 5 additional modules. 17 The HMR is designed with a pre-chamber including stainless steel insert, which reduces the blasting effect of the many shots that are typically fired in a 17 HMR. Thereby, the muffler gets a considerably longer life. Apart from the steel insert, the silencer is produced in high-strength aluminum, like the other Schultz & Larsen silencers. The surface of the silencer is black anodized to protect the surface of the silencer against corrosion. The muffler is only available as the front mounted, as there is no need to reduce the pressure on the small calibers, as the volume of the powder gas is limited.
The silencer is available with a ½ UNF 20 thread, which is a standard thread for small game rifles.
Assembly and maintenance
The silencer is easily mounted without the use of tools. It is screwed onto the pipe until it meets its flange. Only then is the muffler straightened and it will sit straight and centered. The above is under the assumption that the thread of the rifle pipe is correctly rotated by a gunsmith.
The silencer requires a minimum of maintenance. After use, remove the muffler to dry it for any. condensation and rainwater. After approx. 300 shots are used a brass or copper brush in oversize to release any. potting residues around the inner hole, after which vacuuming from both ends.
WARNING! Be aware that the muffler can reach extremely high degrees of heat, so you should not touch it after prolonged firing series.
