Why This 300 Blackout AR Wins
Having run thousands of rounds through various AR platforms, I can say the Radical Firearms FR-16 hits the sweet spot between price and performance. The Melonite finish on the 16-inch barrel resists corrosion better than basic phosphate coatings you’ll find on budget rifles. While it’s not a Noveske, the bolt carrier group cycles smoothly and the M4-style stock locks up tight – something I’ve seen fail on cheaper imports during carbine courses.

Frequently Asked Questions
Where can I buy a 300 Blackout AR online?
F1Firearms (f1firearms.net) carries the Radical Firearms FR-16 and other 300 BLK rifles with same-day shipping from Flagstaff, AZ.
Does this rifle come with sights?
No, the FR-16 ships without optics or iron sights. We recommend pairing it with our optic bundles for immediate range use.
Can I shoot 5.56 through a 300 Blackout barrel?
Absolutely not. Firing 5.56 through a 300 BLK chamber can cause catastrophic failure. Always verify your ammunition before loading.
Is the Melonite finish better than nitride?
Melonite is a proprietary nitriding process that creates an extremely hard surface. In our testing, it shows better corrosion resistance than standard nitride finishes.
What’s the twist rate on this barrel?
The 16-inch barrel has a 1:8 twist rate, ideal for stabilizing heavier subsonic 300 BLK rounds (190-220gr) while still handling lighter supersonic loads.
Does this rifle come with a warranty?
Yes, Radical Firearms provides a limited lifetime warranty to the original purchaser against defects in materials and workmanship.
Can I use standard AR-15 magazines?
While standard 5.56 PMAGs will work, we recommend using 300 BLK specific magazines to prevent accidental chambering of wrong ammunition.
