I advise that folks carry an array of gas block back pistols. rifles, and SMGs along with high quality AEGs that are all well kept and in working order. That gives a small hedge against fluctuations.
At no time should anything clear sully your hands and low quality plastic copies should only be considered as a last resort instead of an achievement upon acquisition. Those should never be photographed and posted online.
