The Ridgeback Defense Rhino S is a 6" titanium 5.56 can that weighs only about 9.5 oz. Ridgeback rates it at a 132 dB average, which puts it among the quietest cans in their lineup, while keeping back pressure low.
It's a lightweight pick for a 5.56 carbine or rifle that you carry a lot. Ridgeback says the Rhino S has the lowest flash of any titanium can they make, with mild sparking only under full auto, and rates it for 3 magazines in under a minute. It fits barrels 10.3" and longer.
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
Rhino S or Rhodie 6Ti?
Both are titanium 5.56 cans at about 9.5-10 oz. The Rhino S is 6" long and very quiet; the Rhodie 6Ti is 0.5" shorter and also handles 6mm. Either is a good light can for a carry rifle.
