Zenith Firearms ZF-56 Features The Zenith Firearms ZF-56 operates on a roller-delayed blowback system an operating method prized for its smooth recoil impulse and mechanical reliability across a wide range of ammunition. The cold hammer-forged 4150 CMV barrel is threaded 1/2x28 and rifled with 6 grooves at a 1:10 right-hand twist which means consistent bullet stabilization and long-term barrel life even under sustained use. A trigger pull weighing 6 to 8 lbs offers a predictable break for follow-up shots while the last-round bolt hold open lets shooters know instantly when the 30-round AR magazine runs dry. The ambidextrous manually actuated safety lever means the ZF-56 can be run comfortably by right- or left-handed shooters alike in fast-paced range or defensive scenarios. Weighing 7 lbs without a magazine the ZF-56 balances well for a pistol of its class and the free-floating M-LOK handguard with integrated heatshield keeps the shooter s support hand protected during extended strings of fire while allowing accessories to mount without contacting the barrel. The buffer tube compatible end cap allows the addition of an aftermarket brace for improved stability and the matte black aluminum receiver stands up to daily handling and field use. Each ZF-56 ships complete with three 30-round AR magazines a high-quality carrying case and a user manual giving shooters everything needed to get to the range immediately. Backed by a limited lifetime warranty the Zenith Firearms ZF-56 is a dependable American-made 5.56 pistol built for range enthusiasts and pistol-caliber platform fans alike.
