RE: Hawken unfinished kit
You have to blue or brown the metal barrel and lock. The brass is as it comes. You also have to finish the stock. This is done a number of ways. The old fashion way was boiled linseed oil rubbed into the wood a little at a time over a long time.With linseed oil the scheduleused to be once a day for a week, once aweek for a month, once a month for a year, and once a year for the rest of your life. Many opt for a stain and a polyurethane coat now..
Many times the lock, nose cap, butt plate cover, and escutcheon plate might not fit exact and you have to set them, so there is a little bit of woodworking skill required. Also you have to set the tang level and true or the barrel will be off. If you're good at wood working and detail work you should be able to do this. If you're not, then you are better off just to purchase the rifle.
I put my Renegade together over 25 years ago, and I am still shooting it.
