Product Description

Through hard use in competition, and in the woods and prairies of America, Bushmaster has PROVEN itself above all other MSRs. Driven by the spirit of innovation that began more than 38 years ago, using improved engineering, manufacturing techniques and advanced materials at its new facility in Huntsville, Bushmaster continues to enhance the ever-versatile MSR platform, and many others. The "AR" in "AR-15" stands for ArmaLite rifle, the company that developed the design in the 1950s. From the Bushmaster workhorse of reliability, the XM-15, to the rapid adaptability of the ACR, to the ultimate long-range tool, the BM50, no other MSR manufacturer offers more cutting-edge firearms innovation for America's competitors, hunters and recreational shooters than Bushmaster. It will always be the mission at Bushmaster to push the limits of performance, so you can push yours. Bushmaster. PROVEN.
