The G.I.S. RSR Steel WB series silencers for self-loading rifles are designed primarily for armed forces, but they are also suitable for sports and recreational shooting.

Therefore, a special emphasis was put in their development and production on maximum durability when firing in full auto, even with the use of supersonic ammunition. The front face is made of grade 15 hardened steel and, like all other the components, is nitrided in order to increase the resistance against damage and corrosion. Therefore, it functions not only as an efficient flash suppressor and protection against the ingress of dirt into the suppressor, it can also be used as a very efficient window breaker for forced entry into vehicles and buildings.

The RSR Steel WB series silencers can be partly disassembled to facilitate their maintenance.

They are supplied in the DC (Direct Connect) design for direct mounting on the muzzle thread or with the QAS (Quick Attach System) interface for quick mounting on G.I.S. flash hiders and muzzle brakes.
