ZENITH ZF-300 300BLK 16" Semi-Automatic Rifle with 30-Round Capacity

The Zenith ZF-300 300BLK semi-automatic rifle is a no-nonsense platform built for shooters who want effective power in a compact, controllable package. Chambered in 300 Blackout—a caliber that punches well beyond standard 5.56 in intermediate distances while taming recoil—this 16-inch rifle delivers the ballistics serious hunters and tactical shooters rely on. Built in America with a roller-delayed blowback operating system, the ZF-300 brings reliability and accuracy to a cartridge that's earned its reputation for versatility, whether you're running subsonic loads through a suppressor or pushing supersonic rounds downrange.

The cold hammer-forged 4150 CMV barrel with 1:10 right-hand twist is threaded and ready for suppressor or muzzle device mounting. A full-length Picatinny rail tops the receiver, giving you unlimited optic mounting options, while the free-floating M-Lok handguard with integrated heatshield keeps things cool and lets you configure iron sights or auxiliary gear without compromise. The last-round bolt hold-open system tells you when you're running dry, and the ambidextrous manual safety lever puts controls exactly where you need them regardless of your shooting hand.

Three 30-round AR-compatible magazines ship with the rifle, so you've got capacity to work with right out of the box. The included buffer tube and compatible end cap let you run stocks and braces as your setup demands, and the adjustable trigger (6–8 lb pull) breaks clean for precision work. At 7 pounds unloaded, this is a rifle you can carry hard and shoot accurately, whether you're hunting in close timber, running drills at the range, or setting up for precision work at distance. A high-quality carrying case and user manual round out what you get.

This is the rifle for 300 Blackout shooters who refuse to compromise on quality, ergonomics, or American manufacturing—a platform that earns its place in your safe and on your shoulder.
