I bought a Romanian WASR 10/63 about a month ago and have done some modifications to it. In that time, I've put about 200-250 rounds through it without any problem (I don't know why the WASR gets a lot of hate, mine was made in 1984 and has been owned by at least 3 other people with 0 problems on functionality) but now I wanna do some modifications to the internals. One of the things that I wanna do is get a new hammer spring, but I'm stuck between the traditional "music braid" style wire and the normal shepherd's hook-type wire (no braids) and I don't know if one is better than the other, the pros and cons, etc to the different style of hammer spring. I'm already gonna get a retainer plate, new trigger assembly (the Tapco G2 is nice, but I wanna try the ALG trigger assembly) and the Kreb's safety lever. But I don't know anything about the different hammer spring styles and if there is any difference or not. Anybody with any knowledge on this would be more than welcome to respond. I'll post some pictures if I need to (don't judge me, the inside is dirtier than a brothel) of what I'm talking about and the AK itself.
