That's the first point of my failure model! I have not neglected this...
"...it's a tolerance stacking issue...the barrel feed cone was too long,..."
Edit: To me, in hindsight, and because Bill Alexander expressed it as a necessary design change from the M16 feed cone, I don't understand why he didn't make that a specification. At least create a maximum depth spec. This is in hindsight, but I think it needs a spec.
