I have a mamba 90 with a 6.5mm shaft but top quality spring seel...i agree with fondue that the standard shaft that comes with the guns are **** if you are afraid of replicas then definitely check..but i would be surprized if someone were to counterfeight spearguns i wouldnt imagine that they sell a lot of volumes (not like mobile phones for example) but worth the check in all cases
