The operations left to be completed are as follows/ fire control group, trigger pin, hammer pin, trigger slot and the safety selector hole. These are our Gen2 80s and have the rear lug area cut out. This is a not an FFL item. This is not a complete receiver and still requires machining to be done. We have a copy of our ATF determination letter and our determination update stating that it is not a firearm."

I have personally machined these, and have not run into any issues (but used a small mill and end mills, not a drill press)... yes, they're hard for aluminum, but nothing my small mill couldn't handle.
Are there crap 80% lowers? hell, yes! are there crap 100% lowers? hell, yes! are there crap BCGs, barrels, LPKs, and just about every other part on ar15s? HELL, YES!!
welcome to capitalism! there will always be somebody trying to make a buck by undercutting quality.


ETA: you want a real challenging project, get some 0% forgings and look up Vader Spade's tutorial on machining it completely...
You even logic Brah ?
