I had a Rifle Basix on a custom KMW with a Surgeon action. After 1K+ rounds, the RB trigger developed creep that couldn't be re-tuned. I called my 'smith and he had recommended to move to a Timney which is what I did.

I have Timney, Shilen, RB, Jewell and TriggerTech triggers. Timneys have never let me down. My first choice these days is a TriggerTech if available for that platform.
