 These rifles are the lightest weight multi-purpose rifles I've ever held, and that's not even the best part. It has the new patented TCS, or Total Compensation System, for the barrel. TCS is a staged compensator, and it's user-friendly. That means nearly zero barrel movement when shooting, and you can change it for left-handed, right-handed, or even different bullet weights, and you can do it all by yourself on the range in just a minute or two. It's that easy.
