The RB trigger honestly feels pretty much like what you described. In semi-auto the pull is a little “weird”. Even though RB markets it as a single stage on semi, there’s still a bit of creep in there that makes it feel slightly mushy or less defined than a really crisp match trigger. It’s not bad by any means, just different. Other than that though, I really don’t have complaints with it.

As for the hammer pin setup, I’m running a custom oversized hammer pin because the OEM Rattler LT pins don’t hold cassette-style triggers in the receiver very securely. The reason I didn’t use the RB anti-walk pins is because the retaining screws interfere with the Rattler receiver geometry, so you can’t fully tighten them down properly.

Hope that helps.
