FAXON PRO 12.5" .338 ARC AR15 PISTOL

The Faxon PRO 12.5" .338 ARC AR15 Pistol is a premium, hard-hitting compact platform engineered for shooters seeking maximum energy in a short-barrel AR, exceptional subsonic performance, and reliable cycling across supersonic and subsonic loads. As part of Faxon's PRO series, this pistol builds on the Sport line with upgraded Match Series components, optimized for the .338 ARC's big-bore capabilities—delivering 1.5x the energy of 300 BLK subsonic while fitting standard AR-15 magazines (with Duramag recommended for best feeding). Ideal for suppressed hunting, tactical applications, or defensive use where punch matters more than velocity.

At the core is the Faxon Match Series Gunner Profile 12.5" .338 ARC barrel—crafted from 416R stainless steel with 5R rifling, 1:8 twist, and black nitride finish inside and out for superior accuracy, barrel life, and corrosion resistance. The pistol-length gas system provides balanced operation in this compact setup, supporting consistent function with heavy subsonic projectiles and supersonic hunting loads.

Use Cases

• Suppressed subsonic hunting: massive energy (1.5x 300 BLK sub) with quiet operation—ideal for hogs, deer, or predators at close to moderate ranges
• Home & property defense: big-bore stopping power in a compact, maneuverable package with low over-penetration potential using subsonic loads
• Tactical / training: hard-hitting feedback with reliable cycling; PRO upgrades ensure durability during high-volume use

Who it’s for: shooters wanting premium .338 ARC performance—subsonic dominance, suppressor readiness, and PRO-series refinements for demanding applications.
Who it’s not for: long-range precision at extreme distances or ultralight builds—this emphasizes energy and compactness over velocity or minimal weight.
