I bought mine about a year ago. It's a Winfield conversion from the early sixties, i/e ramp front sight, no bayo lug. Shoots as good or better than my BM59. Very complicated to take down as there are a lot of small parts, and yes they are expensive due to the fact that only about 30,000 were made. Go to any gun auction site and you will find one or two listed in the $4000 to $7000 range if they are original military issue & in good condition. Bought mine as an investment, I shoot 308 because I like the round, it was cheap untill recently, and I have about the same invested in my M1A, BM59, & a little less in my M1 Tanker (yes I know it's not a real gun, but scoped in 308 it's a blast.
