thanks for the clarification Hungry, youve eased my mind a little and my #### feels slightly more securely attached now.
i just dont understand.. is it so hard to calibrate a machine to drill something in the centre? i could have drilled that more centred with a hand drill while drunk. the gas piston fits in it nice and tight though.
what parts are affected by the metric threading of the Norincos vs the imperial of the USGIs?
ie: what USGI parts wont fit a Norinco?
seems like a non-threaded component like these SEI stainless gas cylinders should fit - will they?
ill take your advice and i wont order one unless i have problems with the Norinco one... im just thinking ahead. will the Norinco gas pistons fit a SEI/USGI cylinder or will i have to also order USGI piston and all the hardware as well?
