Key Features
- Roller-Delayed Blowback System — Why it matters: This system reduces felt recoil and keeps the bolt carrier group running cleaner, so you can shoot more accurately and spend less time cleaning.
- 12-Inch Cold Hammer-Forged Barrel — Why it matters: Cold hammer forging extends barrel life and improves accuracy. The 5/8×24 RH threads let you attach suppressors, compensators, or flash hiders easily.
- Full-Length Picatinny Rail — Why it matters: Mount your red dot, magnifier, or iron sights without extra adapters. The rail is continuous for maximum flexibility.
- Last-Round Bolt Hold Open — Why it matters: You’ll always know when the magazine is empty. The bolt locks back on the last round, making reloads faster and safer.
- Buffer-Tube Compatible End Cap — Why it matters: Want to add a brace or stock later? This pistol is built to accept standard buffer tube assemblies, giving you upgrade options down the road.
Who It’s For
This pistol is ideal for the family shooter who wants a compact, accurate platform for home defense, range practice, or training. New shooters will appreciate the low recoil from the roller-delayed system, while experienced shooters will value the precision of the hammer-forged barrel. It’s also a smart choice for anyone looking to build a suppressor-ready host pistol in .300 Blackout.
Pros & Cons
Pros: Smooth cycling, accurate barrel, easy to mount accessories, last-round hold open, upgradeable buffer tube interface.
Cons: The 12-inch barrel is slightly longer than typical AR pistols (10.5 inches), which may affect concealability. However, that extra length gives you better velocity and accuracy with .300 Blackout supersonic loads.

FAQ
What is the barrel twist rate on the Zenith ZF-300?
The barrel has a 1:8 twist rate, which stabilizes both supersonic and subsonic .300 Blackout loads well.
Can I attach a suppressor to this pistol?
Yes. The barrel is threaded 5/8×24 RH, which is the standard thread pitch for .30-caliber suppressors. Just ensure your suppressor is rated for .300 Blackout.
Does this pistol come with a brace or stock?
It ships as a pistol without a brace or stock. The buffer tube end cap is compatible with standard AR-15 buffer tubes, so you can add a brace or stock later if you choose.
What magazines are compatible with the ZF-300?
It uses standard AR-15 .300 Blackout magazines. Most 5.56/.223 magazines will also work, but dedicated .300 Blackout magazines with anti-tilt followers are recommended for best reliability.
Is this pistol legal in my state?
Laws vary by state and locality. Please check your local regulations regarding AR-style pistols, barrel length, and magazine capacity before ordering.
