I owned a Barret .50, specifically the M-82. It was a lot of fun to shoot. Never had a need for the semi auto function, and all it did was cost accuracy in the end. When the gun market went crazy after the messiah was elected, I sold it for almost $14k. Took the money, and paid off my truck ($5.5k), and bought a new Armalite .50, slapped the same optics on it, along with a purchase of 1000 rnds of .50 BMG, 2000 hulls, 10k primers, 10k bullets, and a new case, scope cover, some scope lens and a few other goodies, and still had almost a grand left over.
In reality, the new weapon is an excellent piece of hardware, and I have no more truck note.
