So I bought a complete upper from a company and put on a lower. Took it to shoot and it would only shoot singles. So I tear it apart and seems like they forgot to drill the hole for the gas port. Is this common? It was a cheap upper. Im gonna let the company have a chance to make it right before I say who it is.
2nd question do I just drill the port myself or send back the upper? I have the tools just never done it before.
