Zenith Firearms
The Zenith ZF-56 5.56mm semi-automatic rifle combines proven roller-delayed blowback reliability with American manufacturing and modern ergonomics. Built on the same operating principle trusted by military and law enforcement worldwide, this 16-inch rifle delivers smooth, controllable shooting whether you're running drills at the range, hunting medium game, or training for home defense. The ZF-56 comes ready to configure: it ships with a buffer tube and stock already installed, an ambidextrous safety lever, and a full-length Picatinny rail for mounting optics and accessories.
The cold hammer-forged 4150 CMV barrel is threaded 1/2x28 RH and built to last; the last-round bolt hold-open feature keeps the action locked back when your magazine runs dry, and the free-floating M-LOK handguard with integrated heatshield lets you customize your setup without worrying about barrel harmonics. Trigger pull runs 6–8 pounds, predictable enough for both rapid fire and precision work. At 7.5 pounds unloaded, it balances speed and controllability for shooters of all experience levels.
Included in the box are three 30-round AR-compatible magazines (all you need to get started), a high-quality carrying case for transport and storage, and a user manual. The buffer tube end cap is compatible with standard AR stocks and tubes, so you can swap components to fit your needs and shooting style. This is a rifle built to be used, maintained, and trusted—no flash, just solid engineering and American workmanship.
