Blackcat Airsoft Replacement Orings for Tokyo Marui M870

The power of gas replicas is a point of reference only, it does not constitute a guarantee of results but an estimation made by the manufacturer. Please take this information into account before purchasing, no warranty service regarding the power can be applied. The power advertised for gas replicas can be highly variable because the cooling of the tank linked to rapid fire, pressure / type of gas used and winter conditions, it is possible to empty all the gas quickly from a magazine, and if there is not enough time given to convert the liquid part into gas, the liquid form then rises through the nozzle as a white cloud. Be sure to use your equipment on suitable climatic conditions and adapt your rate of fire to the ambient temperature to avoid that effect. We recommend that you always choose the manufacturer's brand spare magazines. Choosing a different brand may generate a different power from the original as the percussion valve and magazine lips are not the same.
