Optics planet - great! promag - bad - ProMag Archangel M1A Close Quarters Stock

I have many years of experience with the M14 and M1A. Recently purchased a new $1700 M1A Loaded/Precision with the ProMag/Archangel Precision Rifle Stock (PRS). I found the PRS stock to be too heavy, so purchased the awesome Archangel CQB stock from Optics Planet (great price, great service). Took the PRS stock off the M1A and tried to install on the CQB stock. Barrel and receiver fit perfectly, but even after a 2 hour battle, the trigger group would not seat in the CQB stock (should take 30 seconds to install). During the battle I had to repeatedly pry the trigger group out of the stock with a flat blade screwdriver - did I mention this is a new $1700 rifle? Turned to YouTube for answers and found out that Archangel stocks shrink unless they ship with a removable "Fitting Block" installed in the stock. This was in current and 10 years old videos. Even though the CQB stock I ordered came in a new factory tamper proof package, there was NO fitting block. After a week returned the CQB stock to Optics Planet. BUT it gets better - when I tried re-install the trigger group back into the original/new PRS stock, the trigger group would not fit. Contacted ProMag and they are sending me a Fitting Block for me to install and stretch the stock. PROMAG - every new Archangel stock should be sold with an installed Fitting Block - DUH!!!!
