The Hydra-SS offers durability and multicaliber performance still at an impressively low weight of only 6.5 ounces. It is comprised of a Grade 9 titanium tube and 17-4 stainless steel baffles, which is why we see this can as nearly indestructible.CGS's baffles were inspired by the NASA space shuttle, ORION, to provide increased durability and resiliency. Dare we say... out of this world? Using the standard 1/2x28 direct thread mount, this rimfire suppressor can withstand a fun filled day at the range. After sending rounds through it, you can also easily disassemble and clean this rimfire suppressor using the convenient tool that accompanies it.Rapid Fire Full auto rated!
