I have an upper that won't pick up rounds out of the mag. I've tried different mags and different mag manufacturers, all to no avail. Even cycling the bcg by hand won't work. It does work occasionally, depending on how the mag is sitting. I've also tried different lowers. The BCG is a young's national match that works fine in my other rifles. Could it be the upper receiver? The upper is a custom high end upper (1200+). Anybody ever have this issue? I'm asking only in case the upper works fine for the builder (it's there now) and I get it back.

Try swapping out the bolt and carrier separately and if that doesn't work try each individual part
