The BFG-50™ - the first design from Serbu Firearms - is a bolt action, single shot rifle.

The BFG-50 is constructed using the most modern manufacturing methods and is made from the highest quality MIL-spec alloy steels. In continuous production since 1999, the BFG-50™ was Mark Serbu's first rifle design. It has been thoroughly proven with over 2000 rifles delivered. While the price of this gun is incredibly reasonable, the low quality that one usually expects with a low price is not a fact of life with the BFG-50™. How can this be done? Low overhead, and a design that's optimized for manufacturability as well as performance and quality. The BFG-50™ is a perfect gun for the enthusiast who has always wanted to have a .50 BMG rifle, but doesn't want to spend $3,000+ to get one.

You want low height rings. We recommend IOR Valdada low rings, however, Vortex is said to make a good set of strong low rings.

Ammo Suppliers:

We only recommend that factory manufactured ammo from a reputable source is used.

You can find ammo online from Freedom Munitions, American Marksman, etc. is a great search engine for ammo.  

Great ammo we currently test fire with: American Marksman .50 BMG M33 Ball Ammunition, 660 Grain, FMJ.
