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.

Scopes:
No matter which scope you get, make sure that it is rated for .50 BMG recoil.
SWFA Model SS - approx $350
Rings:
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. Ammoseek.com is a great search engine for ammo.
Great ammo we currently test fire with: American Marksman .50 BMG M33 Ball Ammunition, 660 Grain, FMJ.
I purchased one of these over a decade ago when they were fairly new to the market. Honestly, I didn't expect a lot considering the price. I have been pleasantly surprised with the performance of the gun. I have shot everything from M33s up, with no issues at all. The gun is more accurate at the range than many smaller bore rifles with surplus ammo at the range! Its a basic, simple, but rugged and accurate rifle. You wont be disappointed.
This is a beast!!! very accurate with a good scope. Ate all the ammo I put through it with ease.. More than satisfied with the purchase!!! One of the best BMG's I have shot outside of the military.
I couldn’t be happier , as awesome as the the rifle is , and it’s really great I’m equally happy with the company. My order and the entire process was flawless… this is a very professional company that operates on the highest of standards. Having a 50BMG is a dream come true. Thanks again ??
We fired roughly 50 rounds through the BFG 50 yesterday. Function is flawless, recoil is moderate and accuracy is on point. I fired about 30 rounds myself. The shark muzzle brake is hands down the best I have ever had the opportunity to shoot through. You will not regret purchasing this rifle.
Thanks to the Serbu family a long awaited dream has come true. I am the proud owner of my very own BFG 50 bmg. Thanks to Serbu for building a quality 50 bmg the average working man afford.
This gun has been in my family for 20yrs and been through more rounds then I can count. The accuracy has been true and comparable to the more expensive 50cal. . The customer service has been helpful as well.
The bolt is buttery smooth and it eats lake city surplus ammo no problem!
This was purchased for my brothers and I to have some fun. We took out and only used 3 rounds to sight in at 300 yards. We the put about 40 rounds through it for fun. It never lost its sighting and never jammed. I would recommend to anyone who wants to target shoot or just for fun at the range.
