I picked up an upper made by sota arms from a member a while back. Everyone I talked to said they were junk but mine always functioned great. Hopefully yours does as well.
I had issues at first but it was because I was using flat-point ammo, which caused feeding issues. I polished the feed ramps and switched to regular FMJ ammo, and haven't had any issues since. Got about 800 rounds through it so far.
