My kid got a new a5 for Christmas this morning and it will not cycle at all it shoots 3s and 3.5 good but 2 3/4 suck. Needless to say I am extremely disappointed in the performance of this gun. I cleaned it and lightly oiled it per instructions . My boy had been looking forward to this for a while and all I can say is we got a real expensive single shot at the moment. Has anyone got any suggestions.
