So, a project that could take more than a year; potentially leave you with even more useless parts, and will add up to more than the cost of an assembled rifle, appeals to you? To each their own.
I will say this, I will give mad props to anyone who can complete this difficult project in one year, on a reasonable budget, and have a fully operational M1 at the end. I will pony up some boxes of 30-06.
Talk about negativity!
