Radical Firearms Mk1 Mod1 Personal Defense Weapon 5.56x45mm 6.5 in 30 rounds

The Radical PDW SBR from Radical Firearms is a compact, conversation-starting short-barrel rifle built on the AR-15 platform with a 6.5-inch suppressed-compatible barrel and a 30-round capacity chambered in 5.56x45mm NATO, offering the maneuverability and control that shooters expect from a PDW-style SBR while delivering familiar AR controls and ergonomics; as part of Radical Firearms' MK1 MOD1 PDW lineage, this model targets close-quarters defense, vehicle-borne operations, range training, and duty use where a compact profile matters, and its 5.56 NATO chambering ensures ammo compatibility and flat trajectory for common defense and training loads. The SBR classification means this is an NFA-regulated firearm requiring an FFL transfer and NFA tax stamp, so buyers should plan for the legal process and paperwork; the short barrel and suppressed-ready design reduce overall length and muzzle blast in tight environments, and the 30-round capacity gives sustained engagement potential without frequent reloads. For shooters who want a purpose-built compact AR-15 for CQB drills, tactical scenarios, or a mission-focused truck gun, the Radical PDW SBR combines proven components with an SBR form factor for immediate handling advantages.
