20" wylde barrel and A-2 lower with A-2 butt stock, ejects but wont pick up new round. Only have 12 rounds thru it. low gas block, rifle gas tube, well oiled, tried a pistol lower and it did reload. Bigger gas hole?

Wrong sub forum? ;)

What buffer are you using? I'm guessing if you put a different lower on it and it worked gas port size is not an issue, look at what buffer you have on that lower..

this is also assuming that it hand cycles just fine and that something isn't out of spec on the lower itself.

Check the carrier key to make sure it is on tight. Also check the gas port sizes and make sure they are not clogged. Not everyone comes from the factory the right size or clean.
