Built around the .308 cartridge, the CMMG® Mk3 platform is the larger frame foundation for cartridges such as .308 Win. Material selection is key to a quality rifle, which is why the barrel on this .308 ENDEAVOR is made from 4140 steel with a nitride finish for durability and corrosion resistance without sacrificing performance. When full-size rifles are too cumbersome and pistols/SBRs don’t deliver the long-range ballistic performance you need, this 16" DISSENT Mk3 is the answer accompanied with less felt recoil.
