How did you drill and tap the carrier? I was going to do this same thing but everyone said it’s too hard and would break the tap.

I have 7.5", 10.5" and 12" AR uppers. I like the 10.5" the best. It seems to be the best size length to do everything without being overly long when suppressed.

Carbide end mill to poke the hole. Just a regular tap, but I wasn't sure if wasn't going to break. Went very slow, backing up frequently.

Thanks. I have a milling machine setup and ready to go but wasn’t sure about the tap
