Zenith ZF-300 | .300 AAC Blackout | 30rd

The Zenith ZF-300 is an American-made semi-automatic rifle chambered in .300 AAC Blackout with a roller-delayed blowback operating system. It ships with a full-length Picatinny rail, a cold hammer-forged barrel, and a last-round bolt hold-open feature. The rifle includes a buffer-tube-compatible end cap plus buffer tube and collapsible stock. For an optic under $1,000 that pairs well with this platform, consider the Vortex Strike Eagle 1-6×24 as a versatile, low-profile option for close-to-mid-range work.

Applications: suppressed short-range precision shooting and close- to medium-range hunting where .300 BLK ballistics are appropriate.
