Re: Bushmaster 20" Predator upper ??
I owned a Predator 20" upper, then I sold it. Very accurate but "picky" with ammo. Sometimes it would feed, sometimes not. That situation is a big no-go for me and I sold it. After doing a lot of research, I learned BM used a tight match chamber on this rifle, which was the cause of feeding problems. I now know to look for a Wylde chamber which is both accurate and reliable. Tight so-called "match" chambers do not belong on ARs...period.
