Radical Firearms FR-16 5.56 NATO 16-inch B5 30Rd Semi-Auto

About this product

The Radical Firearms FR-16 5.56 NATO 16-inch is a direct-gas-impingement semi-automatic rifle built on the AR-15 pattern, combining a forged mil-spec 7075-T6 aluminum upper receiver with a 16-inch chrome-moly barrel and a 1:7 twist rate. I've reviewed dozens of entry-mid-level ARs for duty and civilian use, and this platform presents a compelling baseline for the price. It arrives configured for immediate optics mounting and accessory attachment without iron sights.

What is the Radical Firearms FR-16 used for?

This FR-16 is engineered for high-round-count reliability training, general-purpose range use, and field applications where a 16-inch barrel balances maneuverability and terminal velocity. The 1:7 twist stabilizes a wide range of 5.56 NATO and .223 Remington projectiles from the lightest 55-grain FMJ up to 77-grain match loads, though you'll need to supply your own sights and optic. I'd put it in the same functional category as our Stevens 334 in .308 Win for dedicated long-range work – the Stevens is more precise, but the FR-16 is built for volume fire.

How does the Radical Firearms FR-16 compare to a PSA PA-15?

The FR-16 directly competes with the Palmetto State Armory PA-15, often beating it on handguard material and stock selection. Where many entry-level PSA kits rely on basic carbine-length polymer handguards, this FR-16 ships with a full-length, M-LOK compatible aluminum rail measuring 12.5 inches, offering more surface area and accessory positions at no added cost. Both rifles use similar forged uppers and BCG components, but the FR-16's B5 Bravo stock provides a better cheek weld than the standard M4-style stock common on base PA-15 models.

What does it weigh and what are the dimensions?

Unloaded, the FR-16 weighs 6.8 pounds and measures 36 inches from the tip of the threaded muzzle to the butt of the fully extended B5 Bravo stock. With a loaded 30-round aluminum magazine, the weight increases to approximately 7.9 pounds, and the handguard's top rail sits 2.6 inches above the bore centerline for a standard-height optic mount. These figures make it slightly heavier than some polymer-handguard builds but provide a solid, balanced feel that aids in controlled rapid fire.

Who is this NOT for?

This rifle is not for the shooter seeking a true precision instrument or someone unwilling to immediately invest in sights; its mechanical accuracy is typically in the 2-3 MOA range with bulk ammunition, not sub-MOA match-grade performance. It's also not ideal as a dedicated suppressor host because the carbine-length gas system and standard gas port can become over-gassed when adding a can, requiring an adjustable gas block. For hunting applications requiring extreme precision, a bolt-action like the Stevens 334 in .243 Win is a better dedicated tool.

What's in the box?

You receive the complete rifle, one 30-round aluminum G.I.-style magazine, an owner's manual, and a chamber safety flag – no iron sights, sling, optics, or cleaning kit are included. The rifle ships with a thread protector on the 1/2x28 threaded muzzle, which takes 180 foot-pounds of torque to remove, and the bolt carrier group is already installed and lubricated with a light coating of CLP. Plan on an additional $150-$300 for a basic red dot and backup iron sights before your first range trip.

Is the Radical Firearms FR-16 worth it at $498.99?

At just under five hundred dollars, the FR-16 is a solid value for a functional, no-frills rifle that lets you spend your remaining budget on optics and ammunition instead of core components. You're getting a platform with a forged upper, a chrome-moly barrel, and a reputable B5 stock that would cost you at least $650 to piece together individually from major component retailers. The primary compromise is the lack of sights, which is standard at this price point, and a finish that may show wear faster than a premium nitride or DLC coating.
