Thanks for checking out the extractor spring from E-bay - I just put an order in for one myself so I have an extra on hand for my 15-22. I would imagine, (with this good info) the E-bay vendor won't have them around much longer either.
The extractor is a bit tricky to get out and back in, but after you do it a few times, it's pretty easy. I now take it apart every time I clean the rifle because it gets really dirty in there.
Nice looking setup you have there!
Thanks again for the helpful information.
