The Zenith ZF-56/12 pistol chambered in 5.56 (brand part no. ZF56000012) is an American-made semi-auto pistol running a roller-delayed blowback operating system, the same mechanism used in HK’s classic roller-delayed designs. Zenith Firearms builds the 12-inch barrel from cold hammer-forged 4150 CMV steel, threaded 1/2×28, with 6-groove rifling and a 1:10 twist. A full-length M-LOK free-floating handguard with a heat shield and a full-length Picatinny top rail support accessory mounting, and a last-round bolt hold-open system and buffer-tube-compatible end cap round out the build. Three 30-round AR magazines, a carrying case, and Zenith’s Limited Lifetime Warranty ship with the pistol. Among roller-delayed semi-auto handguns, this ZF-56/12 configuration favors shooters who want HK-pattern reliability in a pistol-format 5.56 build.
