Searched and found my own answer.  I'll try that first next time

Do a search on "LRB" or "forged receiver"

This question comes up at least twice a week.

Great question...

If you left your question up, perhaps you would have answered someone elses question.

Yes you are probably right but after peeking around i realised it was info that was everywhere, and my question was a little too simple to get any more info than that which was already being covered in other active threads.  
I asked about the benifits of an LRB gun over a SA M1A.  I should have reworded it as i knew the technical stuff...as in Forged over Cast but was really interested in peoples experiences handling, and shooting the two different rifles.  And reliability.
I just erased it because i know how popular Dupes are around here
