Well,I finally managed to get something good out of this AEG, and actually most of you were right, this was a combination of a few problems that were listed here :
First of all, the inner barrel was warped, I slipped it on a quarter-inch brass rod to straighten it, plus I slightly shimmed it to have a snug fit into the outer barrel, with tape (6 shims, at equal intervals)
Second : The hop-unit was partially declipped from the inner barrel, causing the hop-up to be misaligned. This has been re-installed properly now.
Many thanks for all your help.
