Please use a heat gun or hair dryer to warm up threaded bore of receiver if barrel extension is too tight.) The BCG channel is also smaller for a tighter and straighter fit..
So in your assessment, "a part that is highly manufactured to perform better" is out of spec if it doesn't meet the sloppy fit of +- mil spec TDP. OK, I'll give that to you. JP parts are also out of spec.
I just want others to understand it is better than mil spec, not a gimmick or for cultist as you have ascertained...
Carry on...
BCM receivers aren't "more highly manufactured", they are manufactured no different than any other plus grade forged receiver, except that the receiver extension has a smaller ID. And yes, JP upper receivers do also have an out of spec receiver extension. And John Paul will be the first tell you (as he's told me) that you need to be extremely careful with the barrel extension that you put in it.
Let's go Brandon!
