Alright, the community have spoken. I do admit that i could've gave a more detailed description of the unit ,but since my first language is french and since i am not used to handle RIS or have any knowledge of screws n how to fix them etc..i tried to describe to the best of my ability, but as i said in the pms, i wanted to take a better look at it, but he said his gunsmith should be able to fix it etc...
anyway, i'll respect the verdict and end this dispute : I'll refund him the 140 $ he asked, once i get the unit back.
sounds good ? sorry everyone about this mess...i was kinda in a bad mood these past days and this little episode didnt help, i shouldve fix it with him earlier.
thanks everyone !
