Umarex Smith & Wesson M&P R8 Revolver - BB - 4.5mm

The Umarex Smith & Wesson M&P R8 is not going to win any contests on build materials, it's made mostly out of plastic but it does feel pretty good in the hand and it shoots even better on paper. Combine that with adjustable sights, low cost and an incredible 150+ shots out of each CO2 cartridge, and you have yourself a nice inexpensive BB revolver.
