They fit the Aero perfectly but as you can see they don't stay seated. That picture wasn't staged. I almost reshot it but decided it's a good visual illustration of why #oringsmatter - Recurve tips have a .050" smaller ID then HMM but they're not restrictive at a 60W draw vs the HMM.I have no problem with the fit of the recurve tips on any of my rtas, just wish they were a bit taller.
