Not bad, but there's a lot of things he does in that video that you really have to be careful or you could do some serious damage to your gun. Remember he's an experienced gunsmith and knows what he's doing. He doesn't explain too clearly what, were and how the small parts surfaces are that he's honing. Doesn't explain what grit of Arkansas stone etc. I know what he's doing and I can also do it, but I'm just saying, unless you have done this a few times and have gained experience, be careful, it's not for amatuers! Most guys just do the spring kit change.
