I have had an SKS for about 16 years now. It was one of my first rifles. I don't think I would ever sell it but I am thinking it might be fun to modify it. All the parts have the same serial numbers and it was built in a unknown factory in China. It shoots well and I have taken a few deer with it. Should I leave it alone and start to build an AR or play with it and see how much "gun" I can get out of it.
