IF Oly did pull out from the manufacture's forum for marketing or cash-flow reasons I think they made a big mistake, and should correct it as soon as they can.
I purchased my first AR, an Oly PCR4, based upon three criteria:
1 After reading probably a thousand topics and responses in all of the manufacture's forums it seemed to me that Oly had about as many problems as "ABC", but that there was always Tom answering the questions. Also, when someone had what seemed to be a legitimate gripe he usually said "Call me, here's my number and when I'll be there."
2 Oly's products always seemed first rate. I examined many of their rifles for close to a year at local shows, and compared them to the ABC's rifles. (this does not apply to their FAL rifle, which seemed to have a poor fit/finish)
3 The price was what I was willing to pay.
I bought my Oly due in large part to their forum here.
I will buy another if their quality remains.
Regards, Pepper
