Buying 50 Beowulf... advice needed!!!

[crash32]

I have only been able to find a few 50 Beowulfs that are 100% Alexander Arms, but I am finding many more that have lowers that are from DPMS or Rock River.
Should I hold off for one that has both upper and lower from Alexander Arms or would I be just fine with one that has a different lower? Any pros and cons?????

Different brand lower -should- be just fine. Upper to lower fit can vary even with the same manufacturer. As long as the lower is a decent brand I'd be willing to chance it. My own .50Beo is on a Colt lower, fits just fine. Plenty of people just buy the upper for the AR they already have, don't worry too much about it.
