I acquired 2 of them in the late 1970's, they are older late 50's early 60's suplus varients, and the one I shoot now I acquired in the mid 1990's. And NO! I didnt pay any where near the prices they are asking for them now. The only one I have up and running now is the SAI I bought in the 90's. The other two earlier SA varients will be rebuilt when I can part with the funds to do so.
The M1A is probably the most fun rifle I've shot over the years.
