450 Bushmaster

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. 

The 450 Bushmaster Pistols from Pro2A Tactical are made right here in the USA using US sourced raw materials that is milspec or better quality. Shop our latest line of 450 bushmaster pistols and see the difference!
