Just the bcg out of stock? no problem! - FM Products 9mm Bolt Carrier and Heavy Buffer

I was pleasantly surprised to see that when I could not get just the FM9 BCG, I was able to, for the same price, get the same BCG but WITH a solid steel buffer and 308 flat wound spring, made for AR9 builds. I've built several AR9's over the years and all but one was with the FM9. They run smooth, seem to be tough, and have a great look via the shell ejection port.
