Didn’t fit - V Seven Titanium Mag Catch/Release

Tried this on my Rise lower, the machining was terrible. It didn’t fit because it was not symmetrical at all. I contacted the company and was told it was my “cheap lower”! I returned it and was sent a replacement after many phone calls, and the second one was almost worse than the original one they sent. I ended up just using a cheap one from my parts kit. Fit just fine, despite my “cheap lower”, imagine that.
