The Ridgeback Defense Rhodie 6 is the quietest can in Ridgeback's lineup: the maker rates it at 132 dB and calls its back pressure the lowest of any Ridgeback suppressor. It's an Inconel can built for 5.56 and 6mm rifles, 5.5" long and 1.75" wide, with a deep, smooth tone and very little flash.
Inconel is the alloy you pick when the rifle gets run hard. The Rhodie 6 is full-auto rated and is made for short barrels as well as carbines, so it's a good fit for a 10.3" or 11.5" SBR, a 12.5" or 14.5" carbine, or a 16" rifle that you want quiet without choking the gas system.
This listing is the Flat Dark Earth finish. Each color is its own item, so the can you order is the color you get.
