Building a M14

I purchased a M1A/M14 manufactured in Dec 2009/Jan 2010. I am still very, very new to all this. But I saw two items sell this morning that made me wonder why not build one. It was a Winchester receiver with a matching barrel dated 1963 bolt and few extras, and the other item that sold was a very nice stock with a couple of cartouches and of course had the cut out for the selector switch (I would throw a dummy selector in there). I figure between this board and a couple of fellas I have chatted with and other researching. I will be able to find all parts and get one together, using as many USGI parts as I can. I love my first purchase but I wished I would have found an earlier one but that’s ok. Not sure why I was so unsure about building one. How many have you guys assembled one? Thanks, Billy
