I haven't handled a cyma m14 but the cymas I have handled where pretty decent I was going to buy a cyma myself but it was not meant to be so I did the opposite to you and said fuck it I'll buy the best I can afford and not have to mess with it at all. Your best bet is to get some hands on with both makes and see how you feel its even worth a bit of a drive to a local retailer    

Think your probably right fella. It won’t look anything like a M14 when I’m finished with it.

Up in the man cave I’ve got a TM a Cyma and an AGM and to be honest externally not a great deal of difference , all made of shitty plastic (cyma slightly sturdier than the other two) and the TM has the best external quality/tolerances out of the three so the AGM is in third place but I still think it’s more than good enough as a DMR base gun 👍
