Barrett collaborates on these beauties with Italian shotgun maker Fausti. They offer them in 12, 16 (yes, 16), 20 and 28 gauges. And each receiver is scaled for the specific gauge.
The 28″ scattergun I shot (and wanted to walk off with) will set you back $2,200. Given the quality of the wood, the engraving and the quality of materials and construction, not an unreasonable price at all.
