50 Beowulf

Massive Stopping Power. Zero Compromise.
When standard intermediate calibers aren't enough, step up to the devastating performance of Pro2A Tactical’s Big-Bore lineup. Engineered for modern sporting hunters, brush country defense, and deep-woods tracking, our straight-wall and large-bore AR-15 configurations deliver massive knockdown power out of standard-sized lower receivers.
From ultra-compact thumpers to extended hunting setups, our direct-to-consumer big-bore platforms are precision-built right here in Georgia to out-perform mass-market mass production.
The Pro2A Tactical Big-Bore Advantage:
  • True Left-Hand Ejection Available: You shouldn't have to catch hot, oversized brass in your face. The owner of Pro2A is a lefty himself, which is why we offer fully mirrored left-handed uppers and full-auto cut left-hand BCGs for our 50 Beowulf caliber lineup. 
  • Enlarged Ejection Ports: Avoid frustrating cycle failures. Our big-bore upper receivers feature custom-widened ejection ports engineered explicitly to clear heavy .458 SOCOM, .450 Bushmaster, and 12.7x42 (.50 Beowulf) brass cleanly without marring or stovepiping.
  • Non-Reciprocating Side-Charging Options: For easier manual cycling of heavy cartridges and smoother clearance for large hunting optics, we manufacture highly sought-after side-charging variants across our big-bore platforms. 
  • Custom Feed Ramp Geometry: To combat common big-bore magazine and single-stack feeding drag, our barrels feature hand-polished, wide single-feed ramps to ensure seamless chambering with every pull of the trigger.
