And boy is my face red. Should have read a lot here before jumping in but - bought an AR-10B lower. Then bought a DPMS upper. Imagine my surprise when I went to introduce them to each other. Now, in defense of both sellers - they clearly indicated what they had, even stating the upper was DPMS compatible. I blame myself for not pulling my head out of my butt and thinking about that words actually have meaning.
So - my issue. Does it make more sense to find an AR-10B compatible upper, or get a DPMS compatible lower...? I am not a hard-core user BTW - this gun will just be used for fun shooting... and if the consensus is to stay with the AR-10B, any references for a good source for the upper. (Reasonably priced pleased - is under $450 possible?) Thank you for any input...
