Radical Firearms RF-15 — 5.56 NATO/.223 Rem, 16" Threaded SOCOM Barrel, Mid-Length Gas, 15" M-LOK® Free-Float, B5 Systems Stock & Grip, 30+1 (Model RF01693 / FR16556SOC15SHR | UPC 814034027717)
Built to run hard and shoot straight, the Radical Firearms RF-15 delivers dependable AR performance with well-chosen upgrades that punch above its price. This semi-automatic carbine is chambered in 5.56 NATO/.223 Rem and anchored by a 16" threaded SOCOM-profile barrel for durability under sustained fire. A mid-length gas system smooths recoil impulse, and the 15" M-LOK® free-float handguard adds ample real estate for lights, grips, and bipods without affecting barrel harmonics. Out back, you’ll find proven B5 Systems furniture for a locked-in cheek weld and comfortable control. Finished in anodized black and capped with an A2 flash hider, the RF-15 is a ready-to-roll, modern carbine for range, training, ranch, and duty use where lawful.
Why the RF-15 Stands Out
Balanced Reliability: The mid-length gas setup softens recoil and reduces parts wear compared to shorter systems—faster follow-ups and better control.
Durable SOCOM Barrel: 16" SOCOM profile adds heat mass for improved consistency during longer strings without ballooning weight.
Free-Float Precision: The 15" M-LOK free-float rail keeps external pressure off the barrel, helping preserve zero while offering generous accessory slots.
Ergonomics from B5 Systems: B5 stock and grip deliver a confident shoulder mount, improved wrist angle, and non-slip control in wet or gloved conditions.
Ready for Suppressors/Devices: 1/2x28 threaded muzzle with A2 flash hider from the factory—swap to your preferred brake, comp, or suppressor (where legal).
Quality Controls: An anodized black finish resists corrosion and wear; Radical’s attention to alignment and torque supports long-term reliability.
