I just got in a Range Tool stripped M4 upper receiver for a build I am doing and must say that I am happy with what I purchased. They are a machine shop out of northern minnesota that has apparently been contracting Mil-Spec AR parts for years now. They are now selling directly to consumers, and the prices are outstanding. I picked up a stripped flat-top upper with M4 feedramps for $61. Their website said that they were backed up 3-4 weeks but I still received it in under one week. Just thought I would share my experience, check them out if you want mil-spec quality on the cheap.
Thanks for the notifier sir. Great for those that want to cerakote the upper since you don’t have to blast off anodize prior to degrease-bake-spray-bake-cool-assemble.
Yes thank you
