Zenith Firearms
The Zenith ZF-56 5.56 14.5 Pinned & Welded is a semi-automatic rifle built around a proven roller-delayed blowback operating system, delivering reliable, low-recoil performance in a compact platform. Chambered in 5.56 NATO with a 14.5-inch cold hammer-forged barrel pinned and welded to meet legal requirements, this American-made rifle brings serious capability to shooters who need accuracy and control in a shorter format. Whether you're running drills at the range, building a compact fighting rifle, or looking for a dependable 5.56 that doesn't compromise on quality, the ZF-56 punches above its weight class.
The roller-delayed system keeps things running smooth without the complexity of a direct-impingement design, and the full-length Picatinny rail gives you unlimited optic and accessory mounting options right out of the box. The free-floating M-LOK handguard with integrated heatshield keeps your grip cool during extended shooting, while the ambidextrous manual safety makes this rifle equally comfortable for left and right-handed operators. A last-round bolt hold-open feature helps you manage magazines efficiently, and the buffer-tube-compatible end cap gives you flexibility with stock selection.
You get everything needed to start shooting: a 30-round AR magazine, a quality carrying case, and the user manual. The 6-8 pound trigger breaks cleanly without being hair-trigger, and at 7 pounds unloaded, the rifle handles like something significantly smaller than its ballistic potential suggests. This is a rifle that rewards good fundamentals and honest work on the line.
