Guntec 9mm adapter for AR

If you are considering a Guntec 9mm adapter (colt mags) for your AR lower, keep in mind that it may need some “shaving” to fit. 

Mine wouldn’t fit in an Anderson or Aero Precision Mag well.
The width seems ok but was little too long front to back.

Guntec told me I was the first and asked me to send it back.  I asked them for the spec and tolerances so I could mic the adapter but they haven’t returned my email
