Are the uppers sold as '9mm' uppers cut for feed ramps? If so, M4 or rifle?
I ask because I need a flattop upper that isn't cut for M4 feed ramps. I can't find any in stock at this time. I was considering re-purposing one of your barrel-less 9mm uppers if they are rifle-cut. I see they have forward assists and are drilled for gas tubes, so I assume you just pull normal uppers, put the defector and short-door on it, and call it '9mm'. Any info regarding this would be grand. |
