In the world of AR pistols, few names resonate with the promise of reliability and precision like Radical Firearms. Their 8.5" HBAR 300 Blackout AR Pistol is a testament to engineering excellence, designed for those who demand performance in every shot.
This firearm features MIL-STD upper and lower receivers crafted from forged 7075 T6 aluminum, ensuring durability while maintaining lightweight maneuverability. The Type III anodized finish provides superior corrosion resistance, essential for longevity and consistent operation under various conditions.
The heart of this pistol lies in its barrel—a robust 8.5" piece made from 4140 Chrome Moly Vanadium steel with a Melonite finish that enhances hardness and wear resistance. Its heavy barrel (HBAR) profile combined with an optimal twist rate of 1:8 stabilizes bullets effectively, making it particularly suited for the versatile .300 BLK chambering.
A key feature is the pistol-length gas system paired with a low-profile .750 gas block which guarantees smooth cycling and reliable function across varied ammunition types. The A2 flash hider at the muzzle reduces visible signature during firing—an advantage in low-light situations.
For enhanced accuracy and accessory accommodation, this model includes Radical's proprietary RPR free float rail system—a sleek M-Lok thin rail spanning seven inches—which keeps your hands cool even through extended use while providing ample space for tactical enhancements.
The inclusion of standard components such as MIL-STD forward assist, dust cover, charging handle, safety selector, fire control group ensures familiarity without compromising quality or functionality. Completing this package is a dedicated pistol buffer tube supporting stable recoil management alongside compatibility with common magazine configurations up to thirty rounds in capacity.
