The Ridgeback Defense Rhodie 6K is the short Rhodie: 4.5" long, 1.75" wide and about 12.5 oz of Inconel. It's made for shooters who want a suppressed SBR or short carbine that still handles like an unsuppressed one.
Ridgeback measured it at 136-138 dB on a SOLGW MK1 (5-shot average) with very low back pressure, and rates it for full auto at 6 magazines in one minute. Put it on a 10.3" or longer 5.56 or 6mm barrel and you add very little length to the rifle.
This listing is the Flat Dark Earth finish. Each color is its own item, so the can you order is the color you get.

Questions we get about this can
Rhodie 6K or Rhodie 6?
The 6K is 1" shorter and about 3 oz lighter. The full-size Rhodie 6 is quieter (Ridgeback rates it at 132 dB). Pick the 6K for the shortest setup and the Rhodie 6 for the quietest one.
