The final part needed - Faxon Gen 2 9mm PCC Blowback Full-Mass Bolt Carrier Group, Glock/Colt Compatible

I had been struggling to get an FRT to work in my Springfield Armory Saint Victor 9mm, 5 1/2” AR. I tried a variety of springs and buffers and even went with a longer buffer tube. All the pieces were in place, but it still wouldn’t function. Then I stumbled across some additional information that led me to believe the problem was the old carrier group. This was the fix. Once I put this BCG in the FRT runs like a top. The gun is now as much fun as I hoped it would be.
