I have not heard of any bolts or extensions being out of spec. Get a set of go no go gauges and check. And as much as this will bug the bcl hate group on cgn maybe the cheap brownells bolt may be out of spec. Who am i kidding they will find a way to blam that on bcl some how.
Anything is possible. It's just that with BCL's track record the safe bet is that it's a BCL issue.
I wouldn't rule anything out though.
Why do you defend them? You've been a member long enough that you must know how long they've been letting crap slip out the door. Being one of the few lucky ones that got something that works doesn't erase all the other people's bad experiences. I'm still using an NEA upper and lower in a build I have but I've also had some of their junk pass through my hands and I'll never spend another dime on their stuff.
