Well I have been wanting to take my Encore apart and do a complete spring change. I have had it for 15+ years and wanted to also give it a good cleaning. Over the years I have shot everything from black powder to BH209. I saw a video on Youtube done by M-CARBO that was really one of the most thorough (how to) I have ever seen. After watching it several times I took it on. It went really well and only tricky part was getting the sear/sear spring in. I have to admit if not for the video not sure I would have been able to do it myself.
