The SAINT Edge ATC is built around the patented Accurized Tactical Chassis and is designed to deliver maximum precision in the AR platform. Featuring a monolithic lower/handguard system the SAINT Edge ATC delivers a 100% free-floated barrel ensuring that the barrel barrel nut and gas system are totally free from any contact with the lower chassis.
