Takedown barrel is removed from the upper receiver by moving the slider bar towards the breech, rotating the barrel and pulling it free (no tools required). For installation, slide the barrel into the upper and twist until it locks. The takedown mechanism provides a repeatable point of impact.
A Ruger® flash suppressor is provided, and the 1/2"-28 threaded barrel allows for standard muzzle accessories to be installed.
Patented chrome-plated, two-stage piston with multi-stage regulator provides a cleaner, cooler running, reliable firearm with superior operating endurance. The two-stage piston provides a smooth power delivery stroke to the bolt carrier.
