Spring-Assisted Stopper Ring ⌀6mm

Absolutely wonderful mod that solved a problem I was constantly trying to avoid, not a problem with the product just user error! Love my Hapstone RS and use it daily, the stopper is amazing and I'm so glad I got it

I ordered, it was processed the next day and shipped as well. You can't ask for more than that. Since this order I placed several other orders. All processed very quickly. No issues. Support folk have been fantastic!

Works for Tsprof kadet and works extremely. Priced extreme reasonably too.
