The CMMG Defcan 556 is a suppressor from CMMG. This page stays with the model name on the listing and does not invent a caliber, a length, or a material.

A suppressor is an NFA item. This description of the Defcan 556 does not give legal advice, does not list filing steps, and does not restate a government fee. No separate caliber is printed for the Defcan 556, so this description does not invent one. Read the Defcan 556 as one configuration from CMMG, not as a stand-in for every suppressor that shares the brand.

Additional information is where a specification list would be repeated. If a measurement is not in that list and is not in the name of the Defcan 556, this page does not supply it. When two CMMG listings look alike, compare caliber, finish, and model name only where those fields are filled in. This page is the Defcan 556.

This text is original catalog copy for the suppressor. It is not a pasted manufacturer page, and it does not add promotional claims that are absent from the Defcan 556 listing. Nothing on this page states an overall length, a weight, or a sound rating for the Defcan 556. Those figures are left out when the listing does not publish them. No finish color is called out beyond the name of the Defcan 556, so this description does not assign one.

Use store SKU CMMG-55CA42D when you need this exact item rather than another suppressor with a similar name. No barcode is printed in this description for the Defcan 556, so none is invented here.
