The Ridgeback Defense Rhino X is a 5" Inconel 5.56 can and the most affordable suppressor in Ridgeback's lineup. It's slim at 1.625", weighs about 12.5 oz, and Ridgeback rates it at 136 dB with a deep tone, which is very good for a K-length can.
Inconel makes it tough: Ridgeback rates it for full auto at 6 magazines in under a minute, with minimal flash and low back pressure. To keep the price down it ships with no mount; Ridgeback recommends a direct-thread or Plan-B style mount.
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
Why is the Rhino X less expensive?
It's a shorter, slimmer can and Ridgeback ships it without a mount to keep the cost down. It's still Inconel and full-auto rated.
