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 Raw (Uncoated) finish, bare metal with no coating, which takes on a heat-tinted look as you shoot it. 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.
Who makes it?
