At R/T, we offer more charging handle choices than anyone! There's a reason for this: Our charging handle assemblies work better because our engineered progressive rate springs work better across a much broader range of applications.  Not simply an arbitrary 10% change from spring to spring, but rather a PROGRESSIVE rate that has been determined by many hours of exhaustive testing and development with everything from our 4.5" Quantum Suppressor barrel to a 20" Factory Hammer Forged Target barrel, and everything in between. Got a specific barrel and ammo in mind for your project? No worries= just call ahead and discuss your project, and we will custom match your spring to arrive as you need it already installed on the assembly!

Comes with complete installation instructions, this is a true drop-in part.
