popashot's Review of Guntec USA AR-15 9mm Magwell Adapter Block
I have two of these adapters and have had zero issues with them. One is installed in a 10.5" pistol with PSA lower, PSA gen2 BCG, and PSA Barrel. The other adapter is installed in a 16" carbine with PSA lower, Faxon BCG, and Faxon barrel. Using 4, 20rd C products and 5. 32rd C products mags, These mags fit and function perfectly. DO NOT USE ProMag magazines. They are junk. do not fit in the adapter way too tight and feed lips scrape the bottom of the BCG.
