Serbu Firearms BFG-50 50 BMG (12.7x99mm NATO)36" Complete Specs and Full Gun Specifications

The .50 caliber in question was the RN-50 from Serbu Firearms, Inc. This Tampa, Florida based company is one that I have a great deal of respect for. The founder Mark Serbu is a mechanical engineer that is best known for producing the BFG-50: a .50 BMG caliber, single-shot rifle. Serbu Firearms has always strived to produce high-quality firearms that are either: cool, unique affordable and specifically engineered to stick-it-to-the-man. The RN-50 accomplishes all four.
