What exactly needs to be fitted on the extractor on the Remington 514? I came across a 514 today real cheap, that looks and shoots really good (for a cheap plinker/hunter) but the extractor is broken. I thought it just might be dirty but after some cleaning I found that the "hook" is actually broken off. I found a new one at Numrich but it says that it needs to be fitted. Since I don't trust my local smith to do ANYTHING for me anymore and I'm pretty handy at fitting alot of stuff myself....is this something I should be able to handle? While I've got it apart I'm gonna change out the spring as well.
