Well I went to shoot today and my extractor came out. I lost the spring and the set screw..I know the set screw is a 4-40 x 3/16 that will be easy to find...BUT I have no idea how long or heavy the extractor spring is.....any help would be great! The spring number is MK3-028.
Im sooooo glad I didn't loose the extractor itself!!

chris told me himself that the spring was made out of piano or guitar strings
which i dont recall as i have no musical ability or knowledge of instruments

Sent mine to a gunsmith. he said it was in-fact made out of a piano wire. he said he would beef it up to where it would be better than bohica ever made it so i wouldn't have any more problems out of it. Ill get it back around dec 1st!!
i cannot wait to see it.

piano wire can be found in any r/c hobby shop or mail order from one of the r/c supply houses.

Don't want to sound like a moron....but I knew I could get piano wire but I had no idea what size nor what to do with it once I had it. I didnt know if it had to be bent in a certian way or what...
I have a piano repiar place less than 2 miles from me but i knew I didn't have a clue what to do with it....
