No gas port hole?

I think I would need a drill press to accurately open a hole to allow for the gas return. Everything else seems to be of excellent quality, but there's no way I could install this without specialized equipment. I'm hoping I can initiate a return!

I haven't even installed it yet and it appears to be of absolutely outstanding quality. Pre-drilled for the taper pin holes, it comes with two taper pins and two gas tube retaining pins. Outstanding !
