The Endeavor full-length rifle line from CMMG is ideal for long-range hunts and shooting targets. The Mk4 lower receiver serves as the Endeavor Mk4 lineup's basis. This forged receiver can accommodate aftermarket upgrades including custom trigger groups in addition to being fully equipped with a broad range of CMMG's Zeroed accessories. The Endeavor Mk4 has an 18-inch barrel composed of 416 stainless steel with a nitride finish for longevity and top-notch accuracy. M-LOK slots are located on a CMMG EML15 handguard at the 3, 6, and 9 o'clock positions enabling convenient attachment of bipods, lights, and other accessories. To save weight, the EML15 has Picatinny slots just at the front and back of the handguard. Among other features, the Endeavor Mk4 has an ambidextrous charging handle, an ambidextrous safety selector with a 60 or 90-degree adjustable throw, and a muzzle brake. This is a long-range rifle with mild recoil, great engineering, and exquisite craftsmanship that is built for exceptional accuracy.
