The all-new SAINT Edge Accurized Tactical Chassis, or ATC, from Springfield Armory, uses a monolithic lower chassis and is guaranteed to deliver sub-MOA accuracy.
The rifles, offered in a standard black model as well as an Elite Coyote Brown model with a better trigger and stock, are both built on a one-piece monolithic lower that is machined from 6061 T6 aluminum. Working towards precision use, they both use 18-inch 1:7-twist Ballistic Advantage barrels with .223 Wylde chambers in a truly free-floated design that ensures the barrel and gas system are not in contact with the lower. An Accu-Tite tensioning system eliminates play between the upper and lower.
