Why build an AR chambered in 5.45x39?

An AR-74 combines the familiar controls and modularity of the AR-15 platform with the soft-shooting characteristics of the 5.45x39mm cartridge. Many shooters appreciate its mild recoil, flat trajectory, and unique shooting experience compared to traditional 5.56 NATO builds. Building an AR in 5.45x39 also offers enthusiasts an alternative platform while retaining the customization options of the AR-15.
