My experience for RA tech was a nightmare on WE AK. After installed it, wasn't even cocking almost, just like struck?? Simple answer:WAY OFF SPEC. I had to take it one by one, compare the same part side by side to see which way off spec, then filed it and modified it to make it back as close as original one, it worked. The most depth I filed were about 2-3mm, believe it or not?? So try to compare if that would be the case, good luck!
