Radical Firearms FR16 5.56 NATO Rifle 15" M-LOK Handguard

The Radical Firearms FR16 5.56 NATO rifle combines proven direct impingement operation with modern M-LOK attachment points for versatile tactical applications. This carbine-length platform delivers consistent accuracy and reliable cycling across various ammunition weights. Built on a mil-spec foundation, the FR16 accommodates both civilian sport shooting and professional duty requirements.

What Makes This Different

The 15-inch M-LOK handguard extends nearly to the muzzle, providing maximum rail space for accessories while maintaining a lightweight profile. Unlike traditional quad-rail systems that add unnecessary weight, the M-LOK interface allows users to attach accessories only where needed. The carbine-length gas system ensures reliable cycling with standard 5.56 NATO and .223 Remington ammunition. This configuration balances portability with the stability needed for precision shooting.

Key Features

• Direct impingement gas system with carbine-length gas tube for reliable cycling
• 15-inch free-floating M-LOK handguard with continuous top rail
• Mil-spec lower receiver compatible with standard AR-15 components

• A2-style flash hider with standard 1/2x28 threading
• Six-position collapsible stock with mil-spec buffer tube
• Standard trigger group with approximately 6-7 pound pull weight

Field performance demonstrates consistent 2-3 MOA accuracy with quality ammunition, suitable for both close-quarters applications and medium-range precision work. The free-floating handguard eliminates point-of-impact shifts when accessories are mounted or removed. Weather-resistant finishes on both upper and lower receivers provide corrosion protection in adverse conditions. The platform accepts standard AR-15 magazines and accessories without modification.
