hi,i have the same gun with with same test date on the tag(and by woody).took it out for first time to day(only got 2 days ago)
using 8.4v mini battery,gun shot fine until afternoon when blow back stopped working.(was only using single shot at cqb site)
part 14 the little l shape sledge that is the blow back has snapped.i think the problem is this part is cast pot metal and the fake bolt that springs forward is stamped steel.the square edge of the steel bolt just acts like a shear on to part 14.
ares really need to change part 14 to a machined steel part.i have left it with my local gun te
