Frt install

I was wondering if anyone could recommend any gunsmiths that can help getting my mini kabuto to run , it keeps locking the bolt back after every round and I’m honestly at a loss at what to do. Any help is appreciated as well. TIA

Have you tried an H3 buffer? In our experience, this fixes 70% or so of properly installed FRT issues in AR's.

Are you saying the bolt catch is locking it back or you mean the BCG is getting stuck against the kabuto? You can join us over at r/supersafety, post as many details about your build, photos of internals ideally too, and we might be able to help you get it running.

I was part of OG Kabuto's development test. I've seen and experienced this issue with the OG, not the new mini. Most likely the kabuto's level is dropping too low and caught onto the rear of the BCG. What was suggested was for Kabuto to have a small pen spring, or some sort of blocker to prevent over-travel of the lever; this helps avoid lever dropping too low. If I'm right, try pointing the rifle lower to the ground when you cycle the bcg, this is to test if the lever is truly falling too low due to gravity. Good luck.
