Lightweight Rimfire Design

The CMM-6 is made from aluminium, which keeps its overall weight low at around 130 g.

Its narrow 30 mm profile also helps keep the setup slim and balanced. This makes it well suited to compatible rimfire rifles and other platforms where low weight is important.

Modular Construction

The CMM-6 uses a modular design, which allows the unit to be taken apart for routine cleaning and care.

A-TEC recommends regular maintenance of modular suppressors so that residue does not build up between the sections.

Compatibility

This version is supplied with a 1/2″-20 UNF thread.

A-TEC lists the CMM-6 for compatible rimfire calibres up to .17 HMR, including .22 LR.

Always confirm the exact firearm calibre, muzzle thread and manufacturer rating before purchase.

Sound Reduction

A-TEC lists a sound reduction figure of 22 dBC when tested with .17 HMR.

This figure is a manufacturer test result and should not be treated as a guaranteed result for every firearm or ammunition type.

Actual sound levels can vary due to ammunition, barrel length, firearm design and environmental conditions.

Care and Maintenance

A-TEC recommends cleaning modular suppressors regularly so that residue does not cause the sections to seize together.

The suppressor should be kept dry and stored in a well-ventilated area after use. Threads should also be kept clean and lightly protected from corrosion.

Always follow the manufacturer’s maintenance instructions.

Important Safety and Legal Notice

This product should only be used with a compatible firearm and within its approved calibre and thread specifications.
