The Operator Philosophy

Rock River Arms built the Operator ETR with practical shooters in mind. The M-LOK handguard accepts modern optics and tactical accessories, while the adjustable stock and quality Hogue grip ensure a comfortable fit for various body types and shooting styles. The threaded barrel opens possibilities for sound suppressors or muzzle devices tailored to your needs.

This is a rifle built for those who understand that a carbine should work as hard as the shooter behind it.
