I just bought a used Olympic A2 Upper off Gunbroker.  It doesn't have any markings on it so how do I know it an Olympic and not a DPMS or BM?
Is there a way to tell if it's forged or cast?  Do I care that it's forged or cast?  

It looks brand new and un touched.  I plan to use it for NRA HP and I'll take my current BM flattop and build a sniper rig to replace my Rem 700 in 308.  

Thanks in advance.

Lovesbeer, but shoots safe.

You won't usually see a forge mark on an Oly upper receiver while DPMS & Bushy usually do. Oly used some castings back in the day. If it's a cast upper then you won't see any forging flash under the carry handle. Do you have pics of it yet?

Ok, I couldn't figure out how to post photos without having them on a link somewhere.
