The Centurion 39 is assembled using all new U.S. manufactured parts. It is different from other rifles on the market in that the receiver is machined from an 11 pound block of 4140 ordnance quality steel. The barrel is equipped with a proprietary V shaped Chevron Compensator, designed exclusively by Century. This unparalleled compensator design directs gases upward, which reduces recoil and makes the rifle more controllable. Instead of adjusting for windage from the front sight like other similar rifles, the rear sight is adjustable for both windage and elevation.
