SME Brass Catcher Shooting Accessories. This unique device features an ingenious design that automatically drops the loaded cartridges into a holding tray below the shooting position. This patented design also prevents contamination of brass by preventing dust from contaminating the receiver. The brass catcher unit is fitted with an ingenious base that catches the spent brass trapping it in a container below. This eliminates the problem of brass bouncing around inside the catcher unit. The dual spring loaded edges on the trap body hold the spent brass securely so it can be blown to the ground with a standard broom handle. There is no need for continuous stringing. The catcher unit can be easily secured with the included nylon strap. This model has a slenderer body so it can be used for handguns .
